Sommer Radio Receiver Failure

Opener works from wall button but not from any remote or keypad, even after battery replacement.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Internal receiver module failure on control board, Antenna wire broken, Memory corruption of paired devices

Safety: Disconnect power before inspecting internal wiring.

1. Clear and re‑program: Erase all remotes from memory and re‑program one remote following Sommer instructions.
2. Inspect antenna: Ensure the antenna wire is intact and not broken at the board.
3. Test with new remote: Try a brand‑new Sommer‑compatible remote to rule out transmitter issues.
4. Replace control board: If no remote can be learned or operate the opener but the wall button works, replace the control board.
