Possible Causes

Stuck wall button, Shorted wall control wiring, Neighbor’s remote on same code (older models), Faulty receiver interpreting noise as commands

How to Fix / Troubleshooting

Safety first: Until resolved, keep the door disconnected from the opener or power off to prevent unexpected movement.

  • 1. Inspect wall button: Ensure the button is not physically stuck or damaged. Disconnect its wires at the opener and see if the problem stops.
  • 2. Check wall control wiring: Look for crushed or shorted wires between the opener and wall station. Repair as needed.
  • 3. Reprogram remotes: Clear all remote codes from the Linear opener and reprogram only your remotes and keypad.
  • 4. Observe for recurrence: If the issue continues with wall control disconnected, the RF receiver or control board may be faulty and should be replaced.
