The occurrence of extraneous noise and abrasions of the side of the web can be an indicator that the sealing tape, which is located in the side parts of the guide profiles, has become unusable. For repair it is necessary to remove the protective cover and lower the blade. After loosening the fastening of the side cover, you can raise the blade and remove the guide element. Then it is carefully removed and the sealing element is inserted. When repairing various elements of a roller shutter, it is necessary to take into account all the technical nuances.

DIY roller shutters: installation (assembly), repair. DIY cabinet roller shutters. Do-it-yourself roller shutters
Roller shutters are one of the types of blinds and have the form of a roll with two guides. The latter run parallel to the plates. Do-it-yourself roller shutters can be installed in window, garage and doorways.
Before starting the installation of roller shutters, it will be necessary to carry out certain preparatory work. Initially, the opening must be measured, its diagonals must be compared in order to understand whether these parameters differ by more than 5 millimeters. It is important to analyze how correctly the slopes are located, the permissible deviation from the horizontal or vertical is 1.5 millimeters per 1 meter. There should be no chips or cracks on the surface of the slopes, and if they are plastered, the topcoat should not flake off.
Before making your own roller shutters, you need to prepare the side guides. For this, a marking must be carried out for drilling holes. In order to ensure symmetry, they must be laid in pairs: holes must be made with a step of 15 centimeters from the cutoffs of the guide rails, and only then holes must be made along the entire length with an equal interval of 50 centimeters. If the overhead installation was chosen, the holes should be made closer to the outer edge. When carrying out these works, a drill with a diameter of 8 millimeters should be used. If the installation is to be carried out using outdoor technology, then a through-hole of the tire must be made on both sides, while the top bus must be drilled until a diameter of 11.8 millimeters is obtained. This manipulation is necessary in order to mount the decorative plug.
If you decide to install roller shutters on the gate with your own hands, then the box on each side must be drilled in such a way that two holes are laid through the cover, their diameter should be 4.2 millimeters. They are required to install the rivets after completion of the work. Among other things, you need to make holes to fix the box. With surface-mounted installation, the holes should be located at the back, while with built-in installation - from the top, combined installation involves making holes on both planes.
If you are installing roller shutters with your own hands, then at the next stage you need to make markings for the holes in which the fasteners will be installed. The box is applied to the opening. With surface-mounted installation, all elements must be attached to the wall; with built-in installation, the parts are located on the side and top slopes. Next, you need to check how vertically the guides are located, as well as whether the box is correctly mounted in relation to the horizon. The markings on the slopes through the drilled fixing holes should be made with a marker. You need to drill holes along them, and then drive in dowels. The hole must also be made for the drive.
If you decide to install your own roller shutters for the cabinet, the technology will remain the same. In the next step, you will need to strengthen the frame. First of all, you should remove the protective film, which is located on the back wall. Fixation should be carried out with a screwdriver, then you can fix the controls. If outdoor mounting is used, the controls must be indoors. Next, you can install the canvas, and then the box cover, which is fixed with rivets using a gun.All holes must be sealed with silicone sealant, and then closed with plugs.
If you notice a malfunction, which consists in the fact that the canvas is collected unevenly (this happens, as a rule, most often), then you can easily repair the roller shutters with your own hands. To do this, check the guides for foreign objects. Among other things, the guides can be damaged. But, as a rule, after removal of foreign elements, the uniformity of the stroke returns.

There are the following popular roller shutter malfunctions:
shaft grinding - most likely, the bearing is worn out,
there are scuffs on the canvas on both sides - the silicone inserts are worn out,
in the lower part, the canvas is skewed - the guides are clogged with debris, mainly in the lower part.
When repairing roller shutters, you can encounter two types of malfunctions - minor, when you need to replace a small part, and serious, when you need to dismantle the structure and carry out complex repairs. If in the case of perm you can do it yourself, then in the second case we recommend contacting specialists for the repair of roller shutters, for example, the company Gate Service vorotaservis.com/remont-rolstaven. On the company's website, you can find a lot of useful information on the repair of roller shutters, as well as contacts of the master on occasion, if you cannot solve the problem yourself.
If the bearing is faulty, proceed as follows:
Buy a new bearing,
Lower the blade to the lower position,
Remove the protective cover and shaft,
Remove the pull-out plate,
We change the bearing,
Putting the roller shutter back.
If the roller shutter does not gather evenly at the bottom, proceed as follows:
Check the guides for foreign objects,
Check for mechanical resistance,
Remove foreign objects and check mechanism again.
The most common problems with automatic roller shutters:
The canvas does not rise
The canvas does not drop.
Can you fix these problems yourself? Yes, you can, if you approach the solution of this issue carefully.
If, in the event of lifting or lowering the roller shutter, the canvas practically does not move, while minor movements are accompanied by noise and crunching. Perhaps it is a broken crossbar.
To fix this problem yourself, do the following:
Remove the protective cover,
Check the deadbolt for integrity,
If the bolts are broken, they must be removed,
Install new ones.
If there are scuffs and noise on the canvas along the entire length, then, most likely, the sealing tape is out of order and frayed.
To fix the problem yourself, follow these steps:
Remove the protective cover,
We lower the roller shutter,
We loosen the fastening in the side cover attached to the wall,
We raise the canvas
Unscrew the guide and remove it carefully,
We insert the seal.
The use of roller shutters has gained great popularity among modern consumers. However, over time, under the influence of environmental factors, even the highest quality and most reliable product or its individual element can break down. In this case, it is necessary to carry out repairs, which can be easily done by hand. To get acquainted with some of the nuances of this process, you can watch a video, which provides answers to many questions.
How to repair roller shutters?
It is not difficult to significantly extend the operational period and prevent serious problems. This can be done by hand - it is enough to periodically inspect the bearing and other moving elements. In the photo you can see the components of the roller shutter structure, after which it will be much easier to repair the breakdown.
There are several signs of a problem, for example:
shaft grinding with a collapsed bearing;
scuffs of the canvas that occur when the silicone inserts are worn out;
skewing of the canvas in level at the bottom;
uneven convergence;
clogging due to accumulation of debris in the guide elements.
With a collapsed bearing, the repair process consists of several stages:
we take a new bearing;
we transfer the canvas to the lower position so that it is completely open;
dismantle the protective cover and shaft;
dismantle the broken element and replace it with a new one;
we carry out the assembly of the structure in the reverse order.
If, as a result of using roller shutters, an uneven arrangement of the canvas in the lower part is noticed, you can eliminate this problem with your own hands. To do this, make sure that there are no foreign objects in the guides. In the presence of mechanical damage, it is necessary to carry out repairs, after which you can again check the performance of the structure.
As a result of the operation of the roller shutter structure, various breakdowns can occur, which can be divided into:
The first category includes breakdowns, for the elimination of which it is not required to dismantle the structure, it is enough just to replace the broken parts, for example, cardan, rings, crossbar, guide elements. In case of more serious breakdowns, the repair may require dismantling the roller shutter, if it is necessary to bulkhead the curtain, replace the side covers or eliminate mechanical damage to the box. In the photo you can see the main components of the design.
One of the advantages of protective roller shutters is a simple structure, which, if necessary, can be repaired at no extra cost with your own hands. It is enough to take into account the main nuances and observe safety rules in the process of working with metal structures, having previously studied the instructions for the roller shutter, which indicates the location of the roller shutter system units. If it is necessary to eliminate the breakdown of the gearbox or mechanical damage, which may be evidenced by noise in the box, it is enough to perform several basic steps:
lower the canvas and remove the protective cover from the box;
find the damaged element and fix the breakage;
replace the broken part if necessary;
return the protective cover and the sheet to their original place.
Among the main breakdowns of an automatic roller shutter, the problem of raising and lowering the curtain can be noted. In some cases, it may not move at all. The main reason may be a broken bolt, which can be repaired by hand.In this case, you will need to remove the protective cover and make sure it is intact; if necessary, you can replace the broken part.
The occurrence of extraneous noise and abrasions on the side of the web can be an indicator that the sealing tape, which is located in the side parts of the guide profiles, has become unusable. For repair it is necessary to remove the protective cover and lower the blade. After loosening the fastening of the side cover, you can raise the blade and remove the guide element. Then it is carefully removed and the sealing element is inserted. When repairing various elements of a roller shutter, it is necessary to take into account all the technical nuances.
During the operation of roller shutters, it must be remembered that timely repairs and elimination of minor breakdowns will significantly extend the period of their working condition and avoid serious problems. In addition, weather conditions, temperature drops and mechanical stress can have a negative impact. Therefore, in the event of extraneous noise, you should not postpone the repair for a long time.

As a rule, roller shutters usually have to be repaired at the most inopportune moment. However, it is impossible to hesitate with this, since a minor malfunction can lead to very serious and costly consequences. If you notice even small changes in the work of your design, then you need to immediately seek help. If you have previously serviced the canvas yourself, then do not postpone the inspection indefinitely.
Each mechanism is designed for a certain period of operation. And this does not mean that you can safely use the structure. It is necessary to periodically service the roller shutters in order to identify problems at the earliest stages. Timely maintenance is also necessary in order to replace worn-out parts on time. After all, there are rollers and silicone seals that wear out faster.
Serious breakdowns can occur if the blade has been operated with increased load. Then its service life is simply reduced. But even in this case, it will be possible to repair the roller shutters. The main thing is not to continue operation if you hear extraneous noise during operation.
Extraneous influences and atmospheric phenomena (temperature changes, severe frosts) can also lead to a malfunction of the device. Self-repair of roller shutters is undesirable in this case, since specialists will better diagnose the causes of the problem and fix them faster.
All faults can be figuratively divided into several groups:
breakdown of the electric motor;
blocking the canvas;
the crossbar lock is out of order;
damage to the box.
Failure of the electric motor is the main breakdown of roller shutters. Problems with the power cable, control panel, or switch may contribute to this. Less often, the engine itself or its thermal sensor fails. In this case, the replacement of the broken element is most often required.
If you have returned home and the roller shutters do not open, then in this case it is necessary to call the foremen as soon as possible. Do not try again and again to open it on your own. An on-site specialist will be able to quickly figure out what caused the blockage. This is most often due to faulty guides. The movement also stops if the canvas is deformed: the lamellas diverge, get stuck in the box. The cause may also be a broken cable or springs.
A high-quality bolt lock cannot fail due to a technical malfunction.Most often, its breakdown will be caused by clogging or ingestion of a foreign object. The cause of a serious breakdown, due to which the roller shutters do not rise, may be damage to the protective box. This happens after a heavy object falls on it or the box elements fail.
Not every type of repair will be within the power of a common man in the street. Most often, a call to the master is necessary so that he at least diagnoses the cause of the breakdown. But there are times when you can carry out work on the repair of roller shutters with your own hands. Very often in the autumn-winter period, after precipitation falls, the temperature drops sharply. As a result, an ice crust may form on the surface of the web. When the canvas is opened, it will interfere with him. To fix this, it is necessary to periodically inspect it and gently tap on the surface so that the ice and snow melt.

You can often observe the skew of the canvas at the bottom. Because of this, it does not fit snugly against the wall. In this case, it is not necessary to immediately replace the roller shutters. It is enough to check the guides, in which dirt can simply accumulate.
If you ever encounter similar problems with roller shutters, then do not postpone the repair. The sooner you find the cause, the sooner you can fix it.
Roller shutters are reliable and durable metal structures designed to protect window and door openings from burglary, as well as strong wind and rain. Made of aluminum or steel profiles, the roller shutters are not subject to corrosion and deformation. They could have served for more than a dozen years, if not for the specific breakdowns characteristic of roller shutters.
Use quick links to navigate the page:
Normal wear and tear
Poor product quality
Installation errors
Intensive use
Harsh climatic conditions
Accidental damage to blade or guides
Neglect of the rules of care and operation
Vandalism and attempts to open the structure
Some problems can be easily avoided by ordering roller shutters from trusted companies. Choose organizations that are responsible for their work and provide guarantees not only for the roller shutters themselves, but also for installation. Timely maintenance, which should not be neglected, will help to minimize premature structural wear caused by heavy use, especially in harsh climates. No one is safe from accidental damage and, moreover, vandalism and burglary attempts, and the only thing that remains in this situation is the elimination of damage.
Some faults are easy to fix. For example, dismantling the entire structure is not required to replace the guides. You can do this repair yourself. Other breakdowns are much more complicated and require partial or complete disassembly of the mechanism, and this cannot be done without the help of specialists. Sometimes the cost of repairs is almost equal to the cost of a new structure.
Any repair should start with diagnostics. It is important not only to identify the malfunction, but also to understand the reasons for its occurrence. This does not apply to mechanical damage, when the cause of the appearance of defects is obvious. For example, bent lamellas as a result of burglary or vandalism.
Most of the faults are hidden from view under the protective box:
Roller shutter curtain sagged, skewed or broken
The bolt block on the automatic roller shutters stopped working
The hand drive cord has burst and the blade cannot be opened / closed
The electric motor burned out, the cardan broke, the gearbox was out of order
As you can see, most of the problems are related to the drive and suspension of roller shutters. A visual inspection of these units cannot be performed without first opening the protective box. In these cases, it is necessary to dismantle the box cover in order to accurately determine the cause of the malfunction and then carry out repairs.
Damage to rubbing parts is a common cause of malfunctions. Moving parts of the lifting mechanism (shaft, bearings, gearbox, cardan), which are responsible for raising / lowering the blade, fail due to constant friction. Friction will shorten the service life of manual roller shutters by causing strap or cord breakage. Even the lower transom lock fails, oddly enough, for the same reason.
The solution to the problem that is caused by the wear of the moving part is only replacement. There is no point in trying to fix a faulty node. You will only waste time and money. The repair will not last long, but the most unpleasant thing is that handicraft repairs can lead to more serious damage to the structure. And to even more financial investments.
The type of roller shutter drive - manual or automatic, affects the nature of this breakdown and determines the ways to eliminate it.
Electric roller shutters may require replacement of the bolt or bolt rings.
For roller shutters with a spring-inertial mechanism, it is enough to install a new PIM.
The cardan transmits the torque between the crank and the shaft, due to which the leaf on the mechanically controlled roller shutters rises and falls. The defective universal joint is replaced with a new one, and at the same time it is recommended to install a new bearing.
The movement of the blade is set according to the scheme: knob-cardan-reducer-shaft. The gearbox is the last link that directly rotates the shaft, with the roller shutter attached to it. In the event of a gearbox malfunction, the cardan does not transmit movement to the shaft, respectively, the blade does not rise. If the gearbox fails, its replacement is required.
Problems with the running of the web are not always associated with the lifting mechanism. Quite often, the reason lies in a malfunction of the guide device, deformation of the side tires or damage to the side locks of the roller shutter. In such situations, it is advisable to replace the guide device, and at the same time the guide rollers. Side tire and locks can be repaired, but if repair is not possible then replace.
Manual roller shutters (tape, cord, cord) are raised / lowered by pulling a special tape or a stronger cord. Frequent and / or prolonged use may cause chafing of the drive. Replacing a cord or tape is a fully justified repair.

Replacing the lower bolt lock may be due to its malfunction - then it will be necessary to replace the striker plate or the entire lock as a whole. Another option is the loss of keys. If the problem is with the keys, it will be enough to install a new lock cylinder.
