Possible Causes
Faulty door lock microswitch, misaligned lock mechanism, broken lock lever, wiring fault to lock sensor
How to Fix / Troubleshooting
Safety first: Disconnect power and ensure the oven is cool before working on the door lock.
- Check door closure: Make sure the door closes fully and is not obstructed by racks or accessories.
- Inspect lock mechanism: Access the lock assembly from the top or front (model dependent). Check that the lock lever moves freely when actuated.
- Microswitch test: With the lock manually operated and power off, test the lock microswitch with a multimeter for correct open/closed operation.
- Wiring check: Inspect the harness from the lock to the control board for damage or loose connectors.
Replace the door lock assembly if the microswitch or mechanism is faulty. If wiring and lock are good, the control board input may be defective.
