Possible Causes
Failed door lock motor assembly, Broken or jammed door latch, Faulty door lock switch or wiring
How to Fix / Troubleshooting
Safety First: Disconnect power before working on the door lock mechanism. Avoid forcing the door; glass can shatter.
- Check for obstructions: Inspect the door latch area for bent metal, grease buildup, or foreign objects preventing full latch movement. Clean and straighten as needed.
- Manual release: On some Danby models, a manual door lock release is accessible from the top or rear. Consult the user manual to release a stuck lock.
- Access lock assembly: Remove the top panel or rear panel to reach the door lock motor assembly. Inspect the linkage and switches for damage.
- Test lock motor: With power off, disconnect the lock motor and check for continuity. If open or mechanically jammed, replace the door lock assembly.
- Inspect wiring: Check the harness from the lock assembly to the control board for breaks or loose connectors. Repair as needed.
