Possible Causes

Safety first: Turn off power before accessing the lock mechanism.

Check for obstructions: Ensure nothing is blocking the door from closing fully.
Inspect latch: From the top or front (depending on model), inspect the latch and linkage for broken or bent parts.
Test motor and switches: Use a multimeter to test the lock motor and switches. Replace the door lock assembly if defective.
Control signal: If the lock assembly is good but does not receive power during self-clean, the EOC may be faulty.
