Possible Causes

Loose power plug, Faulty wall control, Intermittent travel module, Overheating motor

How to Fix / Troubleshooting

Safety first: Avoid repeated rapid cycling of the door, which can overheat the motor.

Steps to fix:

  • Check power connection: Ensure the opener plug is secure and the outlet is not loose.
  • Bypass wall control: Disconnect wall control wiring and test using only remotes. If the problem disappears, replace the wall control or its wiring.
  • Inspect travel module connection: Reseat the travel module connector on the logic board.
  • Allow cooling: If the opener has been used heavily, allow it to cool for 30 minutes and test again. Persistent issues may indicate a failing motor or logic board.
