How to Fix / Troubleshooting
Safety first: Disconnect the power and allow the oven to cool completely before working on the door lock. Beware of sharp metal edges.
- Check door closure: Ensure the door closes fully and the latch engages. Adjust the hinges if the door is sagging.
- Inspect lock assembly: Access the top or rear of the oven (depending on the model) to reach the door lock motor and switches. Check for loose connectors or broken plastic parts.
- Test lock motor: Apply power (following service manual instructions) to see if the lock motor operates. Replace the lock assembly if it does not move or the switch does not change state.
- Reset cycle: After repair, clear the error by disconnecting the power for a few minutes, then restart the oven.
