Possible Causes

Repeated obstruction events, Overcurrent protection tripped, Internal self‑test failure, Overheating

How to Fix / Troubleshooting

Safety: Inspect the door and opener thoroughly before repeated testing.

  • 1. Power cycle: Unplug the opener for 5 minutes, then plug back in and observe behavior.
  • 2. Disconnect door: Run the opener with the door disconnected. If it runs normally, the issue is with the door mechanics.
  • 3. Inspect for overheating: If the unit is hot to the touch, allow it to cool and reduce duty cycle (fewer back‑to‑back operations).
  • 4. If protection re‑triggers with no load: The motor carriage or control board may be failing internally and should be replaced.
