Possible Causes
Defective motor start/run capacitor, Seized motor bearings, Excessive load from stiff door, Low supply voltage
How to Fix / Troubleshooting
Safety first: Disconnect power and discharge capacitors before handling. Capacitors can store dangerous charge.
Steps:
- Test door manually: Disconnect the opener and move the door by hand. If stiff, correct mechanical issues first.
- Locate capacitor: In the CAME motor head, find the cylindrical capacitor. Inspect for bulging or leakage.
- Replace capacitor: Swap with a new capacitor of identical µF rating and voltage. Observe correct wiring.
- Check voltage: Have an electrician verify that supply voltage is within specification under load.
If the motor still only hums, the motor windings or bearings may be damaged and the motor unit should be replaced.
