The window does not close
Most often, such a malfunction is observed on windows installed more than 10 years ago. At that time, metal-plastic structures were just gaining their popularity and there were no time-tested mechanisms.
If problems arise with closing, first of all you should carry out a visual inspection of the fittings on the sash and the strikers on the frame.
Trunnion on the sash and strike plate on the frame
An inspection will help detect obvious damage to the fittings, as well as foreign objects that may have gotten into the mechanism and interfere with its normal operation.
Breakage of the strike plate
If everything looks fine on the outside, you should pay attention to other possible causes.
The sash is sagging
A common problem with large blocks with high opening rates. If the window is open in the swing mode, then the first thing to do is to lift the sagging edge of the sash by the handle, insert it into the frame and try to turn the handle to the closed position. If unsuccessful, you need to try to adjust the tilt of the hinges yourself. To do this, remove the decorative trim from them and use a 4-point hex to turn the adjusting screw clockwise.

Incorrect operation of the blocker
The lock is designed to prevent opening in two modes at the same time. Visually, this is a spring-loaded plate fixed on the side of the opening element.
Blockers from various manufacturers
If the lock operates at the wrong time, for example, due to a quick and not entirely accurate turn of the handle when opening, the mechanism may jam. To bring it into working condition, you need to move the plate manually and completely turn the handle to the “open” position.
Other reasons for the incorrect operation of the blocker include deformation of the profile to which it is screwed and incorrect adjustment of the fittings. In such situations, the plate will not accurately fit into the seat on the frame striker and rest against it, preventing closure. The problem is usually solved by adjustment, except in cases where the deformation of the curved profile does not allow this.
Video instructions for adjusting the fittings yourself:
If the lock is completely out of order and does not allow you to close the sash, it is better to dismantle it - the window can function normally for some time without it. On most models of fittings, the assembly with a spring-loaded bar is unscrewed with a regular Phillips screwdriver. On some Maco models it is not removable. On Aubi products, the tongue may unbend over time, and to restore the mechanism to function, it is enough to bend it back into place (usually towards the street).
The fittings of the slot ventilator are in the way
If for any reason this element has changed its original location, for example, due to a loose fastener, then the sash will not be fully pressed against the frame and the handle will not be able to be rotated to the desired position. Adjusting the strike plate is quite simple - it has oval holes for self-tapping screws, along which the position is adjusted. If for some reason the bar cannot be moved, you should try to adjust the mechanism on the sashes.
Setting the axles on the frame in winter - summer mode
The bar, the operation of which is in doubt, can be removed - the sash, if handled carefully, will work normally without it. By removing and putting back all the strips one by one, it is enough to simply identify the faulty one and adjust its position.
Pros and cons of working independently
The advantage of doing it yourself is saving a significant amount , which would go into the master’s pocket. It should be taken into account that at the same time you can carry out lubrication and adjustment, for which they charge a separate fee.
If a similar kit is installed, then only ordinary tools are required, the scope of actions is reduced. The planks simply snap into place, the parts are placed in the same places with the holes, and this is a significant advantage of this case.
But if you install fittings from other brands, you will often need to drill holes, at least for the hinges, as in our example, you will need two additional tools - templates.
This is a disadvantage of this particular option for self-replacement, since the devices are special and it is unlikely that the average user will have them on the farm.
The disadvantage of doing it yourself is that it is quite a troublesome task : you need to select a kit, you will have to remove the heavy sashes, hang them again, you may have to cut the slats. At the end you will need to make adjustments and lubrication.
Top corner won't close
The upper part located above the handle may not close for the following reasons:
- The door sagged. In this case, the sagging is not as critical as in the case described above, and the lower part can fall into place. However, the upper pins will touch the striker, which is usually accompanied by a characteristic knock when trying to close the window. The adjustment is made depending on the installed mechanism. In some cases, it is enough to slightly adjust the position of the strike plate: release the fasteners, lower it slightly and fix it. Roto fittings allow you to adjust the angle of the sash.
Adjusting the standard strike plate - The top canopy is not working correctly. This is common with Aubi movements. The hinge rotates, which is why the corner of the sash on top of the handle is not fully pressed. It can be rotated manually to its original position and the window closed. However, this will only be a temporary solution, since the situation will definitely repeat itself soon. Aubi has closed production, so most likely it will be necessary to replace the mechanism with a new one.

Deal with the breakdown
The window is stuck and won't open
In most cases, the reason is the blocker mentioned above, or rather, its untimely operation.
If you inadvertently turn the handle down in the open swing position and then close it, the lock may operate.
The further sequence of actions depends on the model of the mechanism. First you need to try to re-close and open the sash alternately in tilt and turn modes.
If the handle does not rotate fully to any of the open positions, try the following:
- With one hand, lightly pull the top corner near the hinges;
- At the same time, try to rotate the handle to the swing position;
- Place the trunnion clamping eccentric vertically.
There are situations when the handle is not jammed, but, on the contrary, rotates around its axis, but the sash does not react in any way to the rotation. This indicates a breakdown of the fittings and in this case it is unlikely that you will be able to do anything on your own. The good news is that such breakdowns do not occur suddenly, but it all starts with play in the handle, which increases over time. Therefore, if you take timely measures and replace the faulty part, you can avoid unpleasant surprises.
