Troubleshooting a roller blind that no longer goes up

Roller blinds are practical and aesthetic systems for controlling light and dark in a room. However, over time they can wear out and experience problems. A common problem is that of a roller blind that does not go up anymore. In this article, we will explore the possible causes of this problem as well as the solutions to remedy this inconvenience and find a functional store quickly.

Roller blind that no longer goes up: possible causes

Roller blinds are generally simple mechanisms with few problems. However, when they start to malfunction and get stuck, it can quickly become annoying.

There can be several causes for a roller blind that gets stuck. Here they are :

  1. Obstruction in crank or chain : Dust, hair or other foreign matter can accumulate in the roller blind mechanism, making it difficult to rotate.
  2. Chain or crank stuck or defective : If the element allowing the blind to be rolled up is jammed or broken, the blind will no longer be able to roll up.
  3. Natural wear of components : Over time, plastic or metal parts can wear out and lose their strength, which can make it difficult to reassemble the roller blind.
  4. Problem with the spring mechanism : The spring mechanism may weaken over time or become damaged, which may prevent the roller blind from winding up properly.
  5. Electric problem : motor, remote control or end-of-stroke programming are elements to check on an electric roller blind.

These causes are not exhaustive and there may be other factors causing a roller blind to no longer roll up.

Roller blind that no longer rolls up: how to fix it?

Several solutions can make it possible to quickly unblock your roller blind. However, note that some of them may require professional expertise. If you are not comfortable with the handling, we recommend that you call in a professional to guarantee a safe and efficient repair. Caution: risk of irreversible damage to the awning.

Check the roller blind crank or chain

Most of the time, when your blind gets stuck, the problem comes from the crank or the chain of the roller blind which is defective.

First, if you can see a obstruction in the crank or the cord, try to unblock it with a small brush or a pointed object. Be careful not to damage the lifting mechanism when removing the obstruction.

Then check if the chain or the crank turns freely or if it is totally blocked. In both cases, it no longer drives the winding shaft and it is therefore necessary unlock it and put it back in place on the axis.

1. To replace the crank, it's simple. Just refit it in its gimbal. For this, it may be necessary to dismantle the trunk of the winding axis.

2. To replace the chain of a roller blind, this will depend on the type of lifting mechanism used. Here is how to proceed in most cases to replace the chain of a roller blind:

  1. Remove the side cover that covers the lifting mechanism. You either have to unclip it or unscrew it.
  2. Remove the winding mechanism from the mounting bracket.
  3. Pull the tip at the end of the axle to open the chain mechanism.
  4. Unlock the chain using your fingers or needle-nose pliers. Be careful not to damage the chain or the lifting mechanism when releasing the chain.
  5. Check that the chain connector is located at the top, behind the winding.
  6. Clip the end cap and roller blind back onto the mounting bracket.
Roller blind no longer goes up because of the chain

Note that the steps may vary depending on the type of lifting mechanism used and the manufacturer of the roller blind. We recommend that you consult the manufacturer's manual for more detailed instructions on refitting the chain or to consult a video tutorial to help you in the realization.

If the crank or the chain is defectiveit will take replace it by an equivalent spare part.

Check winding shaft mechanism

It may also be that your roller blind no longer rolls up because of the faulty shaft mechanism. In this case, the chain will certainly turn in a vacuum.

Then check whether the winding system (the chain fastener for blinds) is not damaged. It happens that the plastic part becomes hollow and deformed and that the cord can no longer turn correctly. In this case, replace it. You can find this part for ten euros on merchant sites.

Also check that the fabric is correctly aligned on the axis and that it is not stuck in the installation brackets.

Check roller blind spring

When your roller blind no longer manages to go up, the problem can also come from the spring (note: not all roller blinds have a spring). The role of the spring is to maintain the canvas in each position: open, closed, half-height, etc. If this one is too relaxed where he is broken, it can then no longer function properly and the blind ends up wrinkling or no longer rolling up.

If the roller blind goes up but it does not roll up correctly or not completely, the spring may simply be relaxed. In this case, it will have to be tightened. However, be careful and make sure not to damage the spring by over-tightening it.

If the roller blind no longer goes up at all, it is completely locked in the down position, the spring is certainly broken and it will then have to be replaced.

These processes require dismantle the winding mechanism of the roller blind. If the problem cannot be solved by simply replacing the spring, it may be necessary to replace the entire lifting mechanism.

Check the elements of an electric roller blind

If you roller blind that no longer goes up is electric, it is necessary :

  • replace the batteries in the remote control and test its working condition
  • reschedule the end of races following the instructions given by the manufacturer

If these elements are not responsible for the failure, the problem is certainly due to the engine which will then have to be tested and replaced.

Contact a professional or replace the blind

If the problem is too complex to repair, it may be necessary to replace the roller blind that no longer works as a whole. This solution is certainly more cost effective in the long run if the lifting mechanism is badly damaged and requires professional intervention. Indeed, the price of the intervention and the repair is often very high compared to the base price of the store.

If the problem is minor or your roller blind is still under guarantee, then you can call a professional. You will be assured of having a safe and efficient repair, and at no cost in the event of a guarantee.
