Possible Causes
Manual release left in disengaged position, Worn or loose drive chain/belt, Stripped drive sprocket or carriage teeth, Loose motor shaft coupling
How to Fix / Troubleshooting
Safety first: Support the door to prevent sudden movement when re‑engaging the drive.
Steps:
- Check manual release: Ensure the CAME carriage release lever or cord is returned fully to the engaged position. Move the door slightly by hand to allow the trolley to lock.
- Inspect chain/belt: Look for sagging chain or frayed belt. Adjust tension according to the CAME manual.
- Examine sprockets: Check for worn or missing teeth on the drive sprocket and trolley. Replace worn parts.
- Check couplings: Verify that the motor shaft coupling set screws are tight.
Do not operate the opener with a slipping drive, as it can cause further damage.
