How to Fix / Troubleshooting
Safety first: Allow the oven to cool completely (several hours) before attempting to open the door. Disconnect power before mechanical intervention.
- Wait for cooling: Many locks will only release when the cavity temperature drops below a threshold. Be patient and check periodically.
- Power reset: Turn off power for 10 minutes, then restore and see if the lock cycles open.
- Manual release: Consult the service manual for the location of the manual door lock release (often accessible from the top or rear). Use a suitable tool to gently move the release lever.
- Inspect lock assembly: Once open and with power off, access the lock mechanism and check for damage or misalignment. Replace the lock assembly if it is deformed or the motor is non-functional.
