CAME Lack of Mechanical Locking or Back‑drive

CAME garage door opener does not lock the door; you can easily lift the door by hand when closed

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

No mechanical lock installed on door, Back‑driving operator due to worn gearbox, Manual release not fully engaged

Safety first: For security, do not leave the door unattended until it can be properly locked.

Steps:

Check manual release: Ensure the release mechanism is fully re‑engaged so the trolley locks to the rail.
Test back‑drive: With the opener engaged and powered off, try lifting the door. If it moves easily, the gearbox may be worn.
Add mechanical lock: Install a manual slide lock or CAME electric lock (if supported) for additional security.

If the gearbox allows easy back‑driving, replace the CAME motor unit to restore holding torque.
