Possible Causes
Faulty door lock assembly, Misaligned door latch, Broken door catch, Damaged wiring to door switch
How to Fix / Troubleshooting
Safety first: Disconnect power before working on the door assembly.
- Check door closure: Ensure the door closes firmly and latches with a positive click. If the door feels loose, the latch may be misaligned.
- Inspect strike plate: Adjust the metal strike on the cabinet if necessary so it engages fully with the door lock.
- Access door lock: Remove the inner door panel to expose the door lock assembly. Check for cracks, broken plastic, or burnt contacts.
- Test switch: With a multimeter, test continuity of the door switch when the latch is engaged. If it does not close properly, replace the door lock assembly.
- Check wiring: Inspect the harness from the door lock to the control board for damage, especially near the hinge area.
