How to Fix / Troubleshooting
Safety first: Turn off power at the breaker. The lock mechanism can move unexpectedly.
- Check door alignment: Ensure the oven door closes fully and evenly. Adjust hinges if the door is sagging or misaligned.
- Inspect lock assembly: Access the door lock motor assembly from the top or rear of the range. Check that the latch moves freely and is not obstructed.
- Test lock switch: With the latch in locked and unlocked positions, test the lock switch for proper continuity using a multimeter. Replace the lock assembly if the switch does not change state.
- Check wiring: Inspect the harness from the lock assembly to the control board for breaks or loose connectors.
- Replace lock assembly: If the motor or switch is defective, install a new LG door lock motor assembly and reassemble.
