Possible Causes
Lock motor jammed, Warped latch from high heat, Faulty lock position switch, Control not receiving correct temperature feedback
How to Fix / Troubleshooting
Safety first: Turn off power and allow the oven to cool completely before attempting to unlock.
- Power reset: Turn off power for 10 minutes, then restore. Sometimes the control will reattempt unlocking.
- Manual release: Many Thermador models have a manual lock release accessible from the top or rear. Consult the service manual and gently move the release to unlock the door (power OFF).
- Inspect lock assembly: Once open, inspect the lock motor and latch for heat damage or binding. Replace the lock assembly if necessary.
- Sensor check: Verify the oven temperature sensor is reading correctly; if it falsely reports high temperature, the control may keep the door locked.
