How to Fix / Troubleshooting

Safety: Until resolved, disconnect power when away to prevent unintended operation.

  • 1. Inspect wall button: Ensure the button is not physically stuck or jammed. Disconnect its wires at the opener and monitor if the problem stops.
  • 2. Check wiring: Look for crushed or shorted wall control wires. Repair or replace as needed.
  • 3. Clear and re‑program remotes: Erase all remotes from memory and re‑program only your own Sommer remotes and keypad.
  • 4. If issue persists: The radio receiver section of the control board may be faulty and randomly triggering. Replace the control board.
