Wall control LEDs are off and it does not operate the opener, but remotes still work.

Safety: Turn off power before working on low‑voltage terminals.

• 1. Check connections: Tighten the wall control wires at the opener terminals and at the wall station.
• 2. Test continuity: Use a multimeter to check continuity of the cable between opener and wall station. Replace cable if open.
• 3. Bypass test: Momentarily short the wall control terminals at the opener with a jumper. If the door operates, the wall station or wiring is faulty.
• 4. Replace wall station: Install a new Sommer wall control if wiring is good but the station is dead.
