Possible Causes
Weak or failed door lock motor, Misaligned door latch, Broken lock linkage, Faulty wiring to lock assembly
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before accessing the lock mechanism.
- Check door alignment: Ensure the oven door closes fully and the latch engages the frame. Adjust door hinges if the door is sagging or misaligned.
- Inspect lock mechanism:
- Remove the rear or top panel to access the lock motor and linkage.
- Look for bent rods, broken plastic pieces, or obstructions preventing full lock travel.
- Test lock motor: With power off, disconnect the motor and measure resistance. Replace the door lock motor assembly if open or shorted.
- Check wiring: Inspect harness from EOC to lock motor for loose connectors or damaged insulation. Repair as needed.
- Control test: After repairs, restore power and start a self-clean cycle to verify the lock engages and F91 clears.
