Possible Causes
Stuck lock mechanism, failed lock motor, warped door or latch, wiring issue to lock motor
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker and allow the oven to cool completely if recently used.
- Try a power reset: After cooling, turn the breaker OFF for 5 minutes, then ON. Sometimes the control will attempt to unlock again.
- Manual release: If the door remains locked, remove the top panel (power OFF) and locate the lock lever. Carefully move it to the unlock position to open the door.
- Inspect mechanism: Check for bent parts, broken springs, or melted plastic around the lock assembly.
- Replace lock assembly: If the mechanism is damaged or the motor does not respond to lock/unlock commands, replace the entire door lock motor assembly.
- Verify door alignment: After repair, ensure the door closes and opens smoothly without binding.
Note: Repeated F93 errors indicate a mechanical or motor issue that should be corrected before using self-clean again.
