Possible Causes

Safety first: Disconnect power at the breaker.

Check door closure:
- Ensure the door closes tightly and is not sagging on hinges.
Inspect lock assembly:
- Access the lock and verify that when the motor runs, the latch fully engages and actuates the switch.
- Adjust or bend the actuator bracket slightly if needed to ensure positive switch engagement.
Test switch:
- Use a multimeter to verify continuity changes when the latch moves between locked and unlocked positions.
- Replace the lock switch or entire lock assembly if faulty.
