The average service life of roller blinds is 5-7 years. With careful attitude to them, this time can be increased up to 10 years. However, sometimes during operation, breakdowns cannot be avoided due to the design features of the mechanism. But if you wish, you can repair roller blinds with your own hands, especially if you know the most typical problems.
Hitchhiker or autolock breakage
The problem lies in the impossibility of fixing the curtain fabric at an arbitrary height. You can temporarily get out of the situation by using control circuits in the mechanism, but not every design has them. The fact is that they are screwed to the window profile, which not every customer likes. Therefore, they refuse such a detail.
In this case, the control unit will need to be replaced. Repair of roller blinds is carried out in the following sequence:
- First you need to open the cassette, which will allow access to the movement.
- Can now be dismantled to make repairs easier.
- Remove the mechanism from the cassette,then install a new one.
- Close construction.
You need to handle the corrected curtain as carefully as possible, otherwise you will have to change the mechanism again.
Open or falling out of the control circuit from the mechanism
This problem occurs as a result of incorrect operation of roller blinds. Do-it-yourself repair of the mechanism in this case can also be done. A breakdown occurs, as a rule, due to a strong jerking of the chain in jerks. This leads to the fact that the extreme links simply slip out of the lock, and with the next jerk, the entire chain is pulled out of the control box.
Repair of roller blinds with such a problem is quite difficult. You will need to insert the chain back onto the sprocket of the mechanism, for which you need to open the control unit. All actions must be performed carefully. To do this, you can use a special tool, otherwise there is a risk of damaging the structure and rendering it unusable. After the chain is installed in the mechanism, its free ends must be fixed in the lock. In some cases, it will be appropriate to glue them, but only if this does not affect the functionality of the roller blinds.
If the chain did not slip out of the mechanism, but broke, then it must be replaced. Actions will be similar.
Blade jamming
This breakdown most often occurs when using curtains with poor quality components. For example, if the design uses a plastic control chain. Alsoblade jamming during lifting or lowering can occur in products that have been in service for more than 5 years. Due to long-term operation, the chain balls can move and not fall into the grooves of the sprocket of the mechanism. This causes the chain inside the cassette to expand, after which the curtain jams.
In the first case, the repair of roller blinds consists in replacing the chain with another, higher quality one, for example, with a metal one. But such parts are not commercially available for all types of mechanisms. The replacement of the chain is carried out according to the same technology as when it breaks or falls out of the mechanism.
Twist the fabric on the shaft
The problem is rare, but also possible. It consists in the fact that the canvas is twisted on the shaft and begins to be wound in the opposite direction. This can also lead to tissue tearing. Most often, this problem occurs in the event of a breakdown or loss of the limiter of the upper and lower positions. But there are other reasons too:
- poor quality limiter material, defective design;
- was not fully fixed;
- someone just tore it off;
- Restrictor broken due to constant over-loading.
The solution to the problem is simple - you just need to glue the canvas back onto the shaft or clamp it into a special groove, depending on the type of construction. After that, you should adjust the extreme positions and set the limiters. That's the whole do-it-yourself closed-type roller blind repair.
Damage of canvas
The fabric may become soiled, torn or otherwise deteriorated during use. The solution in this case is the only one - the canvas needs to be replaced. But not always the time or money costs are worth it, so most often they change the entire structure. Electric roller blinds are an exception.
Proper care of the design will increase its lifespan, as well as save both time and money on the possible repair of roller blinds. Therefore, you should carefully study the instruction manual, follow the recommendations there. This is especially true of the intricacies of using the design itself and cleaning products.
