Possible Causes

Faulty pyrolytic door lock assembly, Lock position switch not detected, Over-temperature sensor fault during pyro cycle, Wiring fault to lock motor or switches

How to Fix / Troubleshooting

Safety first: Ensure the oven is cold and isolated from mains power before working on the lock mechanism. Pyrolytic cycles reach very high temperatures.

Check the door lock assembly:

  • Remove the top front trim or control panel to access the door lock mechanism (on pyrolytic models).
  • Inspect the lock arm and linkage for mechanical obstruction or bending.
  • Check the lock motor connector and wiring for damage.
  • Test the lock position switches (locked/unlocked) with a multimeter for correct continuity when the lock is manually moved.
  • If the motor does not run when a pyro cycle is started (with power restored), the lock motor or PCB driver may be faulty.
  • Replace the complete door lock assembly if the motor or switches are defective.

Warning: Never force the door open during or immediately after a pyrolytic cycle. Wait until the oven has fully cooled and the lock has released.
