What's Happening

The oven door lock mechanism didn't engage during self-clean. The self-clean cycle requires the door to be locked for safety at extreme temperatures. The latch may be obstructed, or the lock motor isn't engaging.

How to Fix It

Check that nothing is blocking the door latch at the top of the oven opening. Close the door firmly and restart self-clean. If the latch motor doesn't engage or the mechanism is visibly damaged, the door lock assembly needs replacement.
