How to Fix / Troubleshooting
Safety first: Unplug the opener before opening the housing. Avoid touching live parts.
Steps to troubleshoot:
- Check power source: Ensure the opener is plugged firmly into a dedicated outlet. Avoid using extension cords.
- Inspect outlet: Wiggle the plug gently; if power flickers, have the outlet replaced by an electrician.
- Open housing and inspect: Look for loose connectors on the logic board and motor. Reseat all plug-in connectors.
- Monitor temperature: If the opener stops after several cycles and resumes after cooling, the motor or board may be overheating. Clean dust from vents and consider replacing the motor or board if overheating persists.
