What to do if a window is jammed?

When opening plastic windows, it happens that the sash opens in two modes at once - simultaneously from above and from the side. The situation is not catastrophic - this sometimes happens with all plastic windows. Having understood a little about the operation of the mechanism, it will not be difficult to return the sash to its original position, and also to prevent this from happening in the future.

The window does not open - reasons

To find out how to open a plastic window if it jams when opening, you should determine what led to this situation. There are several reasons that prevent the sash from opening freely. Problems can be caused either by faulty fittings or by deformation of the window frame. Each type of breakdown has its own individual signs that will tell owners what to do.

Handle rotates freely

Often when you try to open a window, the handle rotates in all directions, but nothing happens. In this case, you need to consider 2 possible options:

The handle moves freely and silently both clockwise and counterclockwise, but does not transmit commands to the fittings. This indicates its breakdown - most often the problem is provoked by a cracked case that has ceased to fix the metal pin. Such a malfunction can be eliminated independently by replacing it.
The handle is working, but the commands do not reach the eccentrics that lock the sash. This means that the transmission mechanism - the gearbox - has failed. Such a breakdown is usually accompanied by a characteristic noise: creaking and even metallic crackling. You won’t be able to fix the problem on your own if you don’t have practical skills, so you need to immediately call a technician.

If such malfunctions are detected, no other measures should be taken, since all other actions can cause more serious damage.

The handle is jammed

If the handle of a plastic window is stuck in the closed position and it is impossible to turn it either to the right or to the left, you should immediately call a specialist. Under no circumstances should you try to pry the sash and try to find out for yourself what exactly is broken. Most likely the problem is in one of the knots of the strapping device, but only a master should determine this. The handle can also get jammed due to an incorrectly working lock, which slips when the sash is closed. In order to get to any mechanisms in this case, you need to remove the glass unit and press the sash. Without professional skills, you can ruin something, so it is categorically not recommended to try to save on a visit to a specialist.

The sash is sagging or deformed

The window may be difficult to open because the sash profile clings to the frame or impost. This process is sometimes accompanied by clicks and sometimes even crackling sounds. The opening procedure requires additional effort. The previous performance characteristics of the structure can only be restored by adjusting the hinges. Such repairs do not require the involvement of a specialist and are usually carried out on their own. To avoid mistakes, we recommend that you familiarize yourself with the correct adjustment sequence in the review on WindowsTrade.

Friction and possible jamming of the window also occur due to incorrectly selected hinges or violation of manufacturing technologies when the permissible weight of the sashes is exceeded. In such cases, no adjustment will help, since the problem is of a different nature. It can be eliminated by reinstalling the hinges or simplifying the structure by replacing a double-chamber double-glazed window with a single-chamber one with a selective coating.

A similar situation is possible when the sash is skewed, so it is necessary to distinguish between both types of damage. The problem can only be resolved with the involvement of a specialist. Most often, such repairs are performed on site.

A modern plastic window is a technically complex product, and jamming of the mechanism, handle or sash is not uncommon. Its causes can be both human factor (errors when opening and closing) and various malfunctions.

Below we will mainly talk about problems with tilt-and-turn windows - for example, when the handle for some reason suddenly stops moving, or turns at a small angle and goes no further. There is no need to put any effort into it - so that you don’t have to spend money on repairs or replacement of fittings later. It also happens that a plastic window gets stuck in the frame and does not open or close.

You can fix many problems yourself by reading this material, but in some cases it is better to call a specialist. Let's try to understand the reasons for jamming, how to open or close the window urgently, and what to do next.

If your plastic window is stuck open

Are you trying to close a window for ventilation, but the handle won’t go down? Were you in a hurry closing the window, and now it is open, and the handle is stuck in the “closed” position? Similar problems are typical when the so-called “erroneous opening blocker” malfunctions.

What is a blocker? Where to look for it?

It is usually located on the side of the sash, and is a spring-loaded element of the mechanism, often resembling a plate or button. That is, despite external differences, the common feature of various blockers is that they are always springy. The principle of its operation is as follows: when closing or slamming the window, the lock is pressed and the handle is released. This was done to prevent accidental opening of windows in two positions at once.

The manufacturer's concern for the client's welfare, however, sometimes backfires. If you hastily close the window, the lock may not work in time, and the handle gets jammed. To “release” it, you need to find it and press it, then turn the handle (detailed instructions on how to proceed are here). This way you can quickly restore the operation of a working but incorrectly closed window.

If the sash is deformed or not adjusted, the blocker may slip past its counterpart. It’s easy to check the operation of the mechanism - open the sash slightly and see whether it rests against the bar on the frame when closing or not.

The higher your windows are, the more likely this problem will occur. To eliminate slippage, the easiest way is to use an adjusting key to move the sash towards the handle, and the window’s operation should be restored. After this, you need to adjust the top loop in the same way.

There is no need to follow the advice of some “masters” to place something under the counter part of the blocker. At a minimum, you are guaranteed constant airflow from the handle after such a repair; there may be other problems. The fact is that with this malfunction, you must first of all return the correct position of the sash relative to the frame. The best option would be to adjust the geometry of the sash from the inside by contacting a competent specialist.

Sometimes the locking spring and even its strike plate break down (more often in the case of the Roto NT). In this case, the window can jam at any moment.

What to do in an emergency, or when you can’t adjust the fittings yourself? We'll just remove the blocker and close our plastic window until a replacement is found. In most cases, to do this, it is enough to unscrew just one self-tapping screw with a Phillips screwdriver (note: on Maco it cannot be removed).

With Aubi fittings (pictured below), the blocking element unbends over the years, and if the handle jams, it simply needs to be slightly bent towards the street.

The counter plate of the slot ventilator as a cause of jamming

Sometimes closing the window from the top is prevented by a broken counter strip of the slot ventilator. If its position has changed for some reason (the screws have come loose), or the window has sagged, then the sash is not completely pressed against the frame, and the handle does not turn. The bar is adjusted by moving it left or right; for this, the holes for the screws are usually made oval. Or, as an option, you need to adjust the fittings on the sash themselves.

Note: in order to urgently close a window, you can temporarily remove the “suspicious” part - the blocker, the slot vent strip. Plastic windows, if handled carefully, are fully functional without them. All strikers on the frame can be easily removed and put back one by one. But disassembling the fittings on the sash yourself, unscrewing the screws on it (except for the lock) is categorically not recommended, this can only aggravate the problem.

Damage to the mechanism and foreign objects in it

The cause of the jamming is still not visible? Then look from above into the window mechanism. The fittings could break and block the operation of the handle.

There are also foreign objects - for example, pieces of cement left after installation. They must be removed immediately using a vacuum cleaner. In conventional swing doors (without the tilting function), such debris sometimes clogs the locking gear, preventing the handle from rotating. It is necessary to disassemble and clean the fittings, but it happens that only replacement helps.

How to slam back a stuck hinged sash?

What should you do if the window is folded down, but you can’t press it back - as if something is in the way? Most likely, the mechanism has not been lubricated for a very long time, and the “scissors” are jammed. Lubricate the fittings on top of the plastic window with a suitable product, for example WD-40, and close the sash by pressing harder on it. Do not forget that modern windows require such maintenance at least annually.

Note: although you can use any machine oil, you should not be too zealous with it - excess oil flowing down can render the rubber window seal unusable. It is better to use WD-40 or silicone lubricant; they do not harm the rubber and penetrate well into the mechanism.

If the window is stuck in ventilation mode

The window handle began to move down and got stuck between the open and tilted positions (which roughly corresponds to the slot ventilation mode). Alternatively, it can tilt up, but when turning down, it jams and doesn’t go any further.

Why did this happen, since the window always closed normally before?

This happens if the plastic window was closed incorrectly - when the handle was turned in a hurry, “in weight”, without fully pressing the sash. It happens most often on windows with Winkhaus and Aubi mechanisms and, as a rule, they are far from new. Over the years, the fittings gradually wear out, and such windows need to be closed with particular care.

How to unlock a jammed handle?

If there are scissors available at the top of the window (the metal plate on which the sash is folded), then try vigorously pressing it several times from top to bottom. Then press the window against the frame and try turning the handle again.

Did not work out? You can use another method: pull out the pin of the top hinge, and, lifting it up, put it in its place close to the sash. The window should work again.

Attention! Be very careful that the sash does not fall on you when you remove it from the hinge! Ask someone to back you up if you are not confident in your abilities.

If such jamming occurs, it is better to call a specialist, even if the plastic window was closed - over time it will only work worse. You can completely replace the fittings with new ones, but I also have more budget-friendly solutions: for example, partially disassemble it and remove the worn-out second lock from the scissors. It does not affect the performance of the mechanism (many systems do not have it at all), but the unpleasant situation does not recur. A window repaired in this way will serve you for many years.

Separately about Maco fittings

If the handle is used incorrectly, sometimes a new, fully functional window can become tightly jammed. The fittings are excellent in many respects; they do not like careless handling of the swing-out doors. To unlock it, you need to pull the upper corner near the hinge (there is a gap there) towards you, while simultaneously turning the handle. This is a successful development of events, but it happened that in the process of work I even had to completely pull out the double-glazed window.

No lubrication - there are problems

The fittings may jam simply due to the fact that they have never been lubricated over many years of service. I went out to repair such a window just as this article was being prepared for publication. Based on the description from the owners, I was sure that I would see the same Aubi or Winkhaus, but it turned out to be a Roto NT, which was not properly adjusted during installation, and had not been lubricated for more than 10 years. It was impossible to turn the handle! It's minus 20 outside, and she's in ventilation mode! So an annual “inspection” of windows can save you not only money on repairs, but also a lot of nerves. Of course, it must be performed by a service technician with a good reputation. Unfortunately, the number of cases of fraud under the guise of “free window checks and prevention” has now sharply increased, so be careful.

The plastic window is stuck in the closed position or does not open

Is the blocker to blame again?

If the handle points straight down and does not move at all, this may be the problem described above with a slipped or broken lock. It’s just not easy to get to it now. To open a jammed window, you will have to remove the glazing beads, pull out the glass unit, and, pressing the side of the sash, press the lock. The glass unit must be correctly installed back, placing the adjustment plates diagonally, and its edges are very sharp. The glazing beads are easy to scratch when removed. This rarely happens, and in this case it is better to call a specialist with relevant experience.

Window handle malfunction? Let's check!

It happens that the handle rotates in a circle, but the window still does not open. There are two possible options here. The first - the pin jumped out of the handle, the second - the lock of the plastic window (the locking gear) broke. It's easy to check what happened yourself.

First you need to remove the window handle. To do this, you need to pull the upper part of the base of the handle with two fingers and turn it sideways. Two screws will open, which you need to unscrew. By removing the handle, you will see whether its pin is in place, or whether it is left in the window. The dropped pin can be inserted back into the handle, but it is better to replace it with a new one as soon as possible to avoid repeated breakage. Have you checked the handle? Let's put it in its place.

The locking gear has fallen apart - replacement fittings

If the handle itself is fine, but the window spins in all directions, and a cracking noise is heard when turning it, the lock gearbox is broken.

It is necessary to change, at a minimum, the main lock, and if the window is old enough, all the fittings on the sash are assembled. Most manufacturers do not support the previous lines of their movements. For example, spare parts for the once widespread Roto Centro101 and Aubi 300 systems have long been no longer sold, but there are plenty of “double-glazed windows” with them in Moscow.

Is it worth spending money on repairing a 15-20 year old plastic window?

Of course, mechanism failure is a serious problem and requires the intervention of a specialist. But every cloud has a silver lining - new fittings (if they are of high quality) will easily serve you, with proper care, for another 20 years. Replacing them is much cheaper than installing a new window, and the accompanying repairs in the apartment, and is done without dust and dirt. In addition, it is profitable to repair old plastic windows for one more reason - their profiles, sometimes made in Germany, are usually of very high quality - in those years they did not skimp on materials. The rigidity of the plastic, its composition, and even its color - in most cases, compare favorably with current cheaper analogues. Finding a new seal for them is not a problem at all. As I usually tell clients, these windows are enough for our lifetime!

Window won't open, stuck in frame?

If your window simply stops opening (the handle in the open position does not scroll, but the sash cannot be opened), lift it by the lower part and pull it towards you.

Has it opened? Now the plastic window needs to be adjusted correctly. In a normal, not neglected case, this is not difficult; a 4 mm hex key is enough. But if you try to level a very sagging window by adjusting the hinges, the upper part of the sash may stop closing. This means that your window is skewed and has lost its original rectangular shape. Sagging windows occur due to various shortcomings made during production, and this defect can only be corrected by removing the beads and adjusting the geometry of the sash with special linings for the double-glazed window. You shouldn't do this on your own. An experienced window repair specialist will not spoil the appearance of the sashes, and their operation is guaranteed to be restored. My personal experience shows that after proper geometry correction, regular window adjustment is not required for years!

A little about modern wooden windows

Separately, you can give recommendations to owners of wooden double-glazed windows. When sashes, which are rarely used, sag, jamming sometimes occurs due to the “gluing” of the sashes to the frame. The layers of varnish stick together and the window does not open. To open such a window, you must first lift it by adjusting the lower hinge, and then pull it up by the lower corner with your hands. Click and the wooden window is open. Keep in mind that stains and even damage to the wood may remain on the inside of the frame (however, these windows still require constant care and restoration, unlike plastic ones). Also, wooden window structures can swell when the air humidity is too high or, conversely, dry out when the air humidity is low, which is also fraught with jamming and jamming of the sashes. And the care and adjustment of the fittings of these windows is essentially no different from their plastic counterparts.

The window is jammed in two positions at once, or double opening

This situation often causes panic - the handle does not move, the window hangs on one hinge! Although, if you look closely, on two of them, the upper part is simply hanging out and it seems that it is about to fall out. In fact, fixing the situation is very simple.

We will close the plastic window with you, following the following instructions:

First you need to press the top part of the window (the part that hangs) as close to the hinge as possible. You may not be able to press completely right away, but that doesn’t matter.

Then you need to find the blocker. As a rule, this is a spring-loaded element resembling a plate or button, which protrudes from the side of the sash, on the side of the handle (their photo is above). You need to press your finger on it. If the blocker looks like a plate sticking out at an angle, you should press it towards the seal.

After this, you need to turn the handle up (as if the window was tilted down). If that doesn't work, try decreasing or increasing the pressure on the lock.

And, as soon as the handle turns up, you need to press the top of the sash with your hand to the end, and turn the handle horizontally again. That's it, the fittings are in place, you can close the window!

How to avoid double opening or jamming?

Always use tilt and turn windows correctly. Any – be it plastic, wood or aluminum. This means that there is no need to rush when closing and opening; all rotations with the handle should be done only with the sash pressed to the frame. Do not try to turn the handle while the sash is suspended and not flush against the frame. In the case of very high windows or tilt-and-turn doors, when closing the handle, it is advisable to additionally press the sash with the other hand from the hinge side.

Is your balcony door jammed? There are some nuances here, read this article.

Let me summarize. Although almost anyone can handle improperly closed windows, minor malfunctions and adjustments, it is still better to invite a specialist. In the repair of plastic windows, as in medicine, you need to try to eliminate the very cause of the “disease”, and not its symptoms. The result will be of much higher quality and, most importantly, long-term.

The window does not close - reasons and solution

The nature of these malfunctions is in many ways similar to the problems that arise when opening the doors. They are solved in a similar way, but there are additional nuances that you need to know about.

Jamming of the blocker

In the case of open windows, the issue with the blocker is easier to solve, since there is access to it. The mentioned device is a spring-loaded mechanism and is located on the inner edge of the active leaf. How to troubleshoot problems depends on their nature:

Haste when closing the sash
- such actions often lead to the handle being blocked. Moreover, the window itself may be completely serviceable, so restoring the functionality of a jammed mechanism will not be difficult. In this case, before closing the plastic window, if the sash is jammed, you should first press the lock and then turn the handle.
The blocker slips past the mating part, as a result of which the handle remains inoperative
- it cannot be turned. This mainly occurs due to imbalance of the hinge group or deformation of the sash. If the handle is stuck in the open position, the opening mechanisms must be adjusted to resume correct operation. It may also be necessary to return the skewed sash to its correct rectangular shape.
The locking element has bent
- this can also cause the handle to jam. To restore its functions, you need to press the plate towards the street.
The springs of the locks fail
- such a breakdown can at any time cause the sash to jam. If a faulty spring is detected, the lock must be replaced immediately.

When you can’t quickly fix the problem on your own, it’s best to remove the blocker altogether. To dismantle the device, it is enough to unscrew one or two screws. You can install a new blocker yourself or invite a specialist.

Foreign objects getting into the fittings

The window opening mechanism may become clogged with debris, which prevents the sash from closing. Mostly, such problems are encountered after repairs, if the necessary measures have not been taken to protect the fittings. In this case, frozen building mixtures (cement, putty) or small pebbles interfere with the normal movement of the locking eccentrics. Moreover, even the gearbox can become clogged with debris. To resume normal operation of the window, it is recommended to remove construction dust and crumbs with a vacuum cleaner, and then wipe with a napkin and lubricate the fittings. If this does not help, you will most likely have to disassemble and clean the gearbox. In this case, it is better to call a specialist.

Skewed slot ventilation strip

If the sash sag or the screws loosen, the counter strip of the slot ventilation device may prevent the sash from closing in the upper zone of the light opening. In this case, you need to adjust the position of this element or tighten the screws. To make it easier to find the correct position, the strike plates have oval holes for screws, which allow you to move the element a few millimeters without unscrewing. If attempts to adjust the bar yourself are unsuccessful, it is better to remove it, close the sash and call a specialist.

In the video - identifying cracks during visual inspection

Window repair technicians use measuring tools to determine why a plastic window won't close when ventilated and what to do about it.

If you can’t call a specialist in the near future, you can take independent measures. This is easiest to do for windows that have several operating modes. Usually there are 3 of them - summer, winter and neutral. If the insulation is worn out, the window is switched to winter mode with the sash fitting as tightly as possible to the frame. This is a temporary measure, it does not stop the destruction of the seal, but it stops the entry of cold air.

A more reliable way to fix a plastic window if it does not close is to replace the seal. This action is best left to professionals. It is possible to change the sealing material yourself, but it is risky - it may not fit correctly or be too thick. Cracks, discrepancies or manufacturing defects can be treated only in one way - replacing the window.

The window is stuck in two positions - double opening

This situation is typical for tilt-and-turn windows. If you are not careful when opening/closing the sash or moving it from one position to another, it can both recline and swing open at the same time. In this case, the illusion is created that the sash is supported by only one hinge. In fact, it is held at the top by scissors, so there is no need to panic. To solve this problem you need to follow simple steps in the correct sequence:

The sagging part of the sash, which is located at the top, should be carefully pressed against the frame. It is best to apply pressing force in the immediate vicinity of the loop.
Find the erroneous action blocker on the side edge of the sash on the handle side and press it firmly with your finger.
While holding the lock, turn the handle up until it stops.
If the handle remains in place, you need to press harder on the lock.
After turning the handle up, you will need to press the sash all the way in the area of the scissor hinge.
Return the handle to the horizontal position.
Close a window.

To avoid simultaneous tilting of the sash, do not turn the handle on the sash that is not fully pressed to the frame. This most often happens when windows are closed in a hurry.

Window adjustment methods

The sash may not close if there is something between it and the frame. Small objects brought by rain or wind, such as stones and dirt, can get there. Such an object must be found and removed, then the sash will close. If this is not the reason and the window has sagged, you will have to raise the frame by adjusting the hinges, force the sash to press closer to the frame, and then restore the correct position of the handle.

It is also worth checking to see if the drain plate is misaligned. If you fix the sash by placing any objects under it, the bar may move, causing the window to stop closing; Often this problem can occur after washing a window. In order to return the bar to its place, you need to hit it several times from the end.

Often the user does not know what to do if a plastic window has opened in two positions, if the reason for this is the low quality of the fittings, the elements of which have already failed. In this case, the problem can be solved by replacing the faulty elements.

If you don’t know what exactly is broken and don’t want to disassemble the complex window control mechanism yourself, then it’s better to contact a company specializing in the repair and installation of plastic windows. Its employees will help you repair the window and set it up correctly.

Window jammed in ventilation mode

If the tilted flap does not close in ventilation mode, the problem is most likely due to jammed scissors. Problems in the operation of this practically trouble-free element of the fittings mainly arise due to the fact that they forget to lubricate it. Sooner or later, carelessness leads to a noticeable difficulty in the reverse movement of the sash. To solve the problem, just clean the scissors with a vacuum cleaner and wipe them with a soft cloth, and then lubricate them. For these purposes you can use:

regular machine oil;
professional sprays for window fittings.

More often you have machine oil on hand, but a spray is preferable. It does not leave greasy, dirty marks, is evenly distributed over the metal surface and ensures better sliding of individual hardware elements. In addition, machine oil that gets on the elastic sealing contours can damage them.

First aid for a damaged window

If there are difficulties with the functioning of the structure, the following manipulations can help:

You need to check the handle by gently tugging it. It is best to lift the sash or press it towards the glass unit, if possible.
If the blocker is to blame, you need to press it down and try to open the structure so that you can then close it correctly.
To avoid having to learn how to open a plastic window from the inside, the fittings must be regularly cleaned of dust and lubricated, then the risk of jamming will be much lower.
If individual elements break down, they must be replaced.

When ventilating the window, the handle jammed

In some cases, problems arise not when closing, but when opening the sash for ventilation. Moreover, the difficulties are associated precisely with turning the handle, which gets stuck halfway to the top position. This jamming is explained by the fact that the window was closed in a hurry after ventilation, without fully pressing the sash. Basically, this happens with fittings that have been in use for several years and are already partially worn out. As a result of such actions, after turning the handle incompletely, the window opens slightly at the top, but does not go any further. This type of problem can also be quickly resolved on your own. When the handle of a plastic window is jammed in ventilation mode, you need to involve a technician. Moreover, you will have to call a specialist even if you managed to solve the problem with tilting the sash on your own. After all, such behavior of the fittings indicates its incorrect operation and requires a professional inspection of all the components of the opening mechanism.

The handle does not turn all the way

If the handle does not turn completely or this action occurs only with the use of force, there may be the following reasons:

little lubrication. To do this, you can use both a special substance and car lubricants;
the sash is not in the correct position. To fix this problem, you need to remove the plug and analyze where the most damage occurred. After this, adjust the screws. The process should not take place behind closed doors.

Balcony door jammed

Door blocks are structurally slightly different from window blocks. Their opening mechanisms are supplemented with a special latch, so other methods are used to eliminate the malfunction. If the balcony door is jammed, you need to check this element of the hardware first. However, for inspection you will first need to open the sash. To open a door stuck in a light opening, you will need:

Turn the handle to a strictly horizontal position.
Using the base of the handle, slightly lift the sash.
Pull the raised door towards you.

When opening the sash in this way, you need to be careful not to damage the balcony block. This method of opening is not only inconvenient, but is also only allowed in extreme cases. Regular use will cause more serious damage, so you must immediately adjust the latch. This procedure is performed in several stages:

Using a Phillips screwdriver, unscrew the screws on the counter plate halfway.
The latch is lowered a few millimeters so that its center coincides with the middle of the pin attached to the door leaf.
The strike plate is fixed in a new place.

Changing the location of the latch temporarily and partially solves the problem that may be caused by sagging sash. The canvas may soon drop even lower. This will cause the sash profile to cling to the door frame.

To prevent the plastic balcony door from jamming again, it is recommended to call a specialist to adjust it. The specialist will give the door the correct position and check whether the installed hinges are designed to support the weight of the door.

Most common problems

More common difficulties

If the plastic window does not open due to the handle being stuck in the open position, most likely the lock has been activated.

It is designed to protect the window mechanism from damage when the handle is lowered down when open.

To remove this problem, you should find out the brand of the window that you have installed. Markings can often be found on an iron lock.

If the AUBI mark is placed there, then in the handle area you should find a narrow metal plate with a spring. Pressing it against the seal, you need to test turning the window handle.

This should be done by installing the window sash in a vertical plane; otherwise, the upper blocker will prevent the adjustment of the mechanism.

If a plastic window with window fittings from Winkhaus, GU, Roto or some other company does not open, then you should find a metal tongue under the metal handle, press it against the seal, and turn the handle to its normal position.

The window handle does not turn completely or with force

This discrepancy arises for several reasons. First, the lubricant dries out. You can lubricate the window mechanism and all its moving parts using universal grease or machine oil.

If this does not help, it means that the problem is the sagging of the window sash of the plastic profile.

To eliminate this difficulty, you need to dismantle the decorative plug and find out which specific place in the response is most damaged by the moving roller. At this point you need to adjust the screws of the fittings.

Blowing

This malfunction can be easily removed using eccentric screws. Take a hex key and use this tool to turn the central screw of the strike plate.

The direction of rotation of the screw is determined experimentally. Some companies stuff the fittings roller with a special mark.

Window handle cracked

This is the easiest problem to fix on your own. Replacing the handle of a plastic window begins with turning the mounting plate 90 degrees. Underneath you will find screws that need to be unscrewed.

These screws held the old handle, which can now be removed, a new one put in its place, and secured with screws in the same way.

It is also easy to install a plate that regulates the window in ventilation mode. The window sash opening limiter is fixed under the base of the window handle mount.

Adjusting the plastic window

To do this, you will need to tighten the screws that are located inside the perforation of the fittings.

This process is best done using an imbruce key, which is pre-selected according to the specified size. Otherwise, your best bet is to seek help from a specialist.

Remember that, as a rule, double-glazed windows have a warranty period during which you have the right to receive free service.

Specialists will be able to quickly determine the reason why the sash does not open and eliminate it.

In order for this mechanism to serve you long enough, you need to treat it with care. When switching to ventilation mode, you should slowly turn the knob to a certain position.

To prevent the system from jamming, all actions must be performed in the correct sequence and you need to know what to do, otherwise you can break it even more.

If you are trying to open the sash and the handle is jammed, it means that a special mechanism has switched it to a locked mode, which is designed to protect the plastic structure from external influences:

The first step in troubleshooting this problem is to find out what brand your window is. This can be seen on the metal lock.
When it says AUBI, you need to find the plate on the handle. It is made of thin metal and contains a spring;
Try to press it, and only after that try to turn the handle;
The sash must be in a strictly vertical position, otherwise the lock will interfere with adjusting the mechanism;
If problems arise with fittings from any other company, you should look for a small manual tongue made of steel and press it firmly against the seal;
Next, turn the handle to the desired position.

The handle does not turn all the way

If the handle does not turn completely or this action occurs only with the use of force, there may be the following reasons:

little lubrication. To do this, you can use both a special substance and car lubricants.
the sash is not in the correct position. To fix this problem, you need to remove the plug and analyze where the most damage occurred. After this, adjust the screws.

Air permeability

If this situation occurs in closed mode, then you should use an eccentric screw. This should be done using an imbrus key.

Use it to turn the plate screw. In which direction you should turn, you need to determine yourself. To do this, experiment with turning it in different directions.

The pen is damaged

This problem can be fixed very easily. In closed mode, rotate the mounting plate ninety degrees and unscrew the screws under it. Remove the broken handle and install a new one, securing it with the same bolts.

During the operation of a plastic window, a situation may arise where one or another part breaks down. This in no way threatens you with a complete replacement of the structure.

First of all, you should find out the cause of the breakdown, and then begin the process of eliminating it. You must clearly know how to properly repair the mechanism, otherwise ignorance can lead to even more serious damage to the window and its complete replacement.

What to do if the windows are jammed due to the opening being skewed

This type of breakdown can only be determined by a specialist. In critical situations, such malfunctions are signaled by cracked double-glazed windows or a deformed profile. In most cases, this problem can only be solved by installing new windows. Most often, with minor distortions of the openings, the sashes jam only when the dimensions are incorrectly determined and the windows are made with large dimensions. To avoid such breakdowns, during the manufacture and installation of windows it is necessary to strictly comply with the technologies and requirements of GOSTs.

Looking for a reason

In order for a plastic window to last a long time, it needs regular care. Experts advise checking the condition of the sashes and fittings annually. Problems with windows most often arise precisely because of insufficient care and operational errors. Less often due to manufacturing defects or incorrect installation. One of the most common situations is that the window sash is open in 2 positions, but the handle is jammed. As experts note, in 90% of cases this problem occurs due to incorrect operation of the fittings. To minimize such cases, you need to carefully select a manufacturer. For economy class windows, we can recommend Salamander. Here you can see the price of Salamander windows.

What to do to prevent windows from jamming

It is impossible to completely eliminate the likelihood of breakdowns, but reducing their number is within the power of every window owner. The best prevention is regular maintenance of the opening mechanisms. You can perform such procedures yourself. They do not require special tools or materials that are not commercially available. OknaTrade has published detailed material on how to take care of fittings. Practical recommendations from this article will help to avoid not only jamming of the sashes, but also many other breakdowns. In addition, during operation the following precautions should be observed:

do not leave windows open in strong winds to avoid strong impacts;
do not turn the handles until the sash is pressed tightly against the frame;
do not rush and do not open the window until the handle is installed in the correct position;
Do not use excessive force when closing/opening the doors.

Compliance with these simple rules will significantly extend the life of windows without major repairs or replacement of components. After all, the cause of many breakdowns is careless handling of profile structures. Some faults that cause windows to open incorrectly can be eliminated yourself, while others can only be eliminated with the help of a specialist. However, in any case, if there are problems with the operation of the fittings, in the foreseeable future you will need to call a specialist. After all, a minor malfunction may in fact be the initial sign of a major breakdown, and only a professional can determine this.

Even when the operation of a window or door unit is quickly restored on your own, it is recommended to conduct an expert inspection of the structures to identify all hidden faults.

The window sash is sagging

Window sashes sag when they are disproportionately large compared to the hinges. This is a common problem with large windows and those that are rarely used in both positions. To prevent the hinges from becoming deformed, it is advisable to tighten them regularly. If the windows are new and still under warranty, you don’t need to solve this problem yourself; it’s much safer to turn to specialists.

If there is no one to call for help, try to correct the situation with your own hands. Lift the sash, press it firmly against the frame and turn the handle, restoring its natural position.
