How can I fix a garage door motor that runs but doesn't move the chain?
If your garage door motor is running but not moving the chain, there are a few potential causes:
- Disengaged gear: The gear that connects the motor to the chain may have become disengaged. Check to see if the gear is properly aligned and engaged.
- Damaged chain: The chain may be damaged or broken, preventing it from moving. Inspect the chain for any damage and replace it if necessary.
- Loose or damaged sprockets: The sprockets that guide the chain may be loose or damaged, causing the chain to slip. Tighten or replace the sprockets as needed.
- Electrical issues: There may be an electrical issue preventing the motor from powering the chain. Check the wiring and connections to ensure they are secure and there are no shorts or breaks.
- Malfunctioning motor: In rare cases, the motor itself may be malfunctioning. If none of the above solutions resolve the issue, it may be necessary to replace the motor.
