Roller shutter repair: causes of breakdowns and their prevention

Roller shutters are an effective way to protect entrance doors and windows from any attacks, vandalism, climatic or weather influences. A large number of moving parts increases the risk of roller shutter failure. There are many reasons for breakdowns - high loads, natural wear, attempts to open the protective fence and other impact factors.

General breakdowns of roller shutters and roller shutters of any kind

Web deformation

Uneven opening and closing, the entry of foreign objects into the movement zone and the structure of the canvas, the accumulation of snow and ice on it and other influences damage the canvas. The slats (horizontal sections) wrinkle, warp, move apart, and get stuck. To correct the problem, a rebuild or replacement of the canvas is required - partial or complete. This may require replacement of the hangers.

When the canvas is deformed, side plugs, crossbar and locking locks and the drive may also break - see these breakdowns below.

Box deformation

The fall of heavy objects from above onto the roller shutters causes the frame to collapse. As a rule, compacted snow and ice from the roof fall on the box. As a result, the canvas “snacks” and cannot work properly. The problem is solved by straightening or replacing the box, depending on the degree of deformation.

Deformation of guides

In case of careless operation or mechanical damage (large boxes, carts), the guides on the structure become crushed. After this, the canvas “bites” and stops working correctly. Repairs require straightening or replacing the guides, depending on the degree of deformation.

Options for mechanical damage and ways to eliminate them

Minor damage to roller shutters

In some cases, with minor damage, the master may advise straightening the damaged slats or frame, but in any case it will not be possible to return the original shape. In case of damage, it is recommended to order the required number of new lamellas and replace them; this is easier than straightening the old ones and the structure will not lose the necessary rigidity.

Significant damage to protective roller shutters

In the event that the canvas has become unusable due to an attempted burglary or similar damage, you should not even think about straightening such a product. In any case, the roller shutter will lose its attractive appearance and strength characteristics, which will weaken the structure in the future. Therefore, you should order a new canvas entirely and replace it. You can replace the canvas yourself; it is not difficult and does not require special skills.

Damage to the box or guides

Damage to the protective box is often caused by falling ice or a break-in attempt; such damage is typical for surface-mounted installation on the facade of a building. The box consists of several stiffening ribs and thin sheet metal; if it is damaged, repairs are often not made; it is much easier to order a new box for replacement. The situation is similar with the guides; these are elements that must be smooth because when bending the blade will get stuck or jam, and in any case, damage to the guides will require their replacement.

Breakdowns in automatic roller shutters

Protective roller shutters with an electric drive are much more convenient to use, since no effort is required; the roller shutter itself raises and lowers the curtain using the control panel.

If a roller shutter on an electric drive has stopped showing signs of operability, you should not immediately worry about damage, there may be no power in the network or a wire has come loose due to which the electric motor does not receive power and does not try to raise the curtain. A similar situation will occur in cases of low voltage; the motor will not be able to lift the blade if the network voltage is below 207V

Thermal protection

The motor of electrically driven protective roller shutters is equipped with an emergency shutdown system in case of overheating; therefore, when the roller shutters are actively used, the product may temporarily shut down; this may mean that the motor has overheated and needs to cool down for some time to continue working.

Setting the end position of the roller shutter

The electric drive has special limit switches with extreme position regulators. If the roller shutter is completely lowered, but the motor continues to work, you should adjust the extreme upper and lower positions so as not to put excessive load on the electric motor. A similar situation occurs if the roller blind is not completely lowered and the engine is turned off in advance, which means it is necessary to add a few additional revolutions using the regulators.

Changing control from manual to electric drive

This is not a breakdown, but a standard recommendation; when buying a gate, it is better to immediately buy a system with an electric drive, since it works from a remote control and allows you to control the roller shutters without leaving the car. Many customers replace the control by installing an electric drive. After installation, no additional actions are required.

Breakage of deadbolt locks due to deformation of the canvas

If the roller shutter is opened and closed incorrectly (jerky, etc.), foreign objects get into the roller shutter structure, or other mechanical impacts occur, the canvas becomes skewed. At the same time, the slats move apart and become wrinkled, and the deadbolt locks break.

In this case, it is necessary to install new deadbolt locks or dismantle, clean and reinstall broken locks. In this case, the canvas usually requires partial or complete reassembly or replacement.

Fallout of side plugs with jamming of the blade

Under mechanical influences such as foreign objects getting into the roller shutters, accumulation of snow, ice, etc. on the roller shutter, the side plugs on the curtain fly out and it “jams.” This is the most annoying problem.

In this case, you have to completely sort out the canvas. The price of the plugs themselves is low, but reassembling the canvas is very labor-intensive, which increases the cost of repairs.

Can I repair it myself?

The possibility of self-repair of roller shutters is determined by the type of fault. Most breakdowns require replacement of the failed unit. You need to have some knowledge to find the right parts. You will also need tools, materials, and the ability to handle them.

If the part is severely deformed, it will have to be replaced. This procedure sometimes requires complete dismantling of the entire structure and reinstallation after replacement. All these actions require experience and high qualifications, otherwise the roller shutters can be completely damaged as a result. Any misalignment, incorrect assembly or other errors made during repairs will cause new, more serious problems.

If problems arise, it is recommended to seek help from specialists. They will quickly identify the problem, take the necessary actions, and ensure the functionality of the structure. The result of the work of professionals is always of much better quality, and the cost of paying for services is lower than purchasing or installing new roller shutters. The City Blinds company provides such services.

Breakage of locking locks and drive due to deformation of the canvas

In automatic roller shutters and roller shutters, mechanical influences (ingress of foreign objects, etc.) often lead to deformation of the canvas and malfunctions of the locking locks (locking bolts) on which the canvas is suspended from the shaft.

The roller shutter stops working correctly. Symptoms can be varied, for example: the blade does not move when the shaft is running idle, the blade is not screwed onto the shaft correctly, warps, gets stuck, jams, etc.

In this case, repair or replacement of faulty locking locks is required. If the canvas is significantly damaged, it also requires reassembly or replacement - partial or complete.

In case of such breakdowns, the drive or its limit switch block may also burn out; This problem can be solved by replacing the drive.

Automation breakdowns due to inappropriate power supply

Automation problems in roll-to-roll systems often occur due to a) voltage fluctuations in the network, b) insufficient power supply, or c) improper installation of the power cable inside the box.

The roller shutter stops working altogether or does not work correctly/reacts to control commands: it does not open or close properly, etc.

These problems can be corrected by replacing the fuse (if it is blown) or replacing the drive (if it is faulty). In this case, of course, it is necessary to ensure the supply of a stable appropriate voltage to the roller shutter.

What can you do before contacting specialists?

What can you do yourself if the roller shutter or roller shutter jams?

Roller shutters (roller shutters) and roller shutters (roller shutters) can become jammed during operation. Most often, the cause of this problem is incorrect opening and closing of the roller shutter (jerky, uneven) during manual control or the entry of foreign objects into the structure (including snow, ice in winter). In automatic roller shutters and roller shutters, this problem can arise due to voltage fluctuations in the network.

If this situation occurs, we strongly recommend that you do not pull or yank the roller shutter with your hands . This approach can only contribute to even greater deformation and, therefore, aggravate the problem.

What can be done in this case before contacting specialists?

If manually operated roller shutters are jammed

You can open the box of the structure and see what is preventing the movement of the canvas. If you see that the canvas has shifted in the guides, you can try to restore its correct position (perform all actions with extreme caution) . Sometimes in this way it is possible to restore the functionality of the roller shutter on your own. If this approach does not solve the problem, call a qualified technician.

If automatic roller shutters are jammed

When an electric roller shutter jams, first of all you need to check the fuses and package switches on the distribution board and the fuses in the roller shutter control unit (if equipped). If the problem is a blown fuse, just replace it. If the fuse is normal, you need to check whether there is sufficient power supply to the roller shutter drive. A simple way to do this is to turn off (de-energize) all consumers at the distribution board, leaving power supply only to the roller shutter (observe safety precautions!). If after this check the roller shutter starts working again, the jamming occurred due to insufficient power supply, therefore, it is necessary to ensure the supply of appropriate power.

If these steps do not help resolve the problem, you should contact qualified specialists.

I live with insulated roller blinds, although in an apartment on the 1st floor. So I have roller blinds between the bars and the windows. I rate them very positively, firstly, they really provide insulation. Example - if there is severe frost, windows with uncovered roller blinds freeze up to 20–30 cm from the outside, if the roller blind is closed no more than 10 cm. Secondly, protection from the wind, if there is wind, sometimes you cannot open the window for ventilation, even in the upper position, with Roller blinds can be opened and ventilated in any wind, rain or snow. Thirdly, no one will look through the window. There are two downsides: if it gets wet and frost hits, they can freeze (though I haven’t had this happen since they are made deep in the window), the second, as protection, they just can’t throw anything at the window - it will bounce off - they are quite rigid and springy. As a defense they are of no use. That's why I use grilles and roller blinds.

I am depressed by the imperfection of control systems. With 22 windows, I would like to be able to close them all at the touch of a button without overloading the electrical system, i.e. the next roller blind/group must close after the motor of the previous one stops. No control system takes this wish into account.
