How to Fix / Troubleshooting

Safety first: Disconnect power before tightening hardware. Do not place hands near moving parts when testing.

Steps:

Inspect door hardware: Check rollers, hinges, and brackets for wear or looseness. Tighten bolts and replace worn rollers.
Check opener mounting: Ensure the CAME rail and head unit are firmly attached to the ceiling and header bracket.
Lubricate drive: Lightly lubricate the chain or screw drive with a suitable lubricant. Do not over‑lubricate belt drives.
Listen to motor/gearbox: If noise clearly comes from the motor head and persists after other fixes, the internal gearbox or bearings may be worn and require replacement.

Persistent loud grinding usually indicates internal gearbox damage; replace the motor unit.
