Knowing why a Somfy wall switch is not working, the wise thing to do is to check out all the factors that cause them to malfunction. Below are some of the faults you can look for and how to fix them.

Check Your Motor Batteries

The first thing to check when your switches stop working is your motor batteries. Use a tester to check if all of them are working. If one is bad, then change all the batteries since they may get bad soon, especially if they were bought at the same time. Also, some testers are cheap and won't always give proper results.

You should also check if the batteries are aligned properly to the spring. If the spring is shorted out, you will need a new battery tube.

Here are some tips to help you handle your battery tubes:

  1. Do not allow them to slip off and fall, it can damage the wiring.
  2. Always hold the tube sideways when replacing the batteries. If you hold it in an up-to-down direction, it can damage the battery or the tubes.
  3. Always arrange the battery so that all of them are pointing in the same direction.
  4. Check and recheck if the batteries are fixed properly.

Check Your Remote

It is easy to examine the remote control. You can check if it is working by pressing the direction buttons. If the LED illuminates, then your battery is fine. You should check out other problems, too.

The Somfy remote uses batteries. They use them to store energy so they can function properly.  Some units use a 2430 Lithium 3V  type of battery.

  1. With a screwdriver, loosen the screws at the back of the remote control.
  2. Take the back lid off and replace the battery correctly.
  3. Check on the battery and remote. Check the negative and positive points and replace the batteries in the same arrangement.

  2. Then, remove the faceplate and pry off the switch with a small screwdriver.
  3. Change the batteries and replace the faceplate, and switch.

Check The Motors

Your switch may have a problem with its motors, though it may not necessarily be a major problem. The Somfy motors are made with heat regulators, so they don't fry out easily because of overuse.

These regulators stop the motors from working after 3-4 minutes of constant use. When this happens, you should allow the motor for about 15-20 minutes to cool down before trying it again. 

If you have tried this and it still doesn't work, try changing the motor batteries. If the rails are still stuck, it shows that the motor control board is damaged. You should call customer service for a replacement or purchase a new one.

Check The Wiring

Poor installation can cause great injury to appliances. If your connection was made with wires, check out the wires and their plugins. If you don't know how to go about it or you notice wrong wiring somewhere, the best thing to do is to reach out to your retailer dealer or the installer.

Inspect For Interference Problems

Another is interference problems, which can be caused by cellular phones, lighting dimmers, RF house phones, microwave ovens, LED and plasma TVs, short wave radios, fluorescent lights, computers, AM and FM radio signals, and the like.  

Since Somfy switches use remote control, signal interferences can also be a problem. This problem is often overlooked, but here are some techniques you can do to make your switch work if this is the issue.

  1. Modify the direction of the antenna by moving it gently.
  2. Set the antenna in such a way that it does not touch anything.

Other Factors To Consider

Other factors can be range problems. You should consider how far from the switch the remote can get to and make sure you are within that range. Then, you can also clean the rails, specks of dirt, dust, or dead insects that may get stuck in them.
