Display shows F8, oven may not start self-clean or may stop mid-cycle.

Safety first: Disconnect power before accessing the lock mechanism. Surfaces may be hot after a recent cycle.

Steps:

• Check for obstructions: Inspect the door latch area for debris or baked-on residue preventing full lock engagement. Clean as needed.
• Manual test: With power OFF, access the lock motor assembly from the top or rear. Manually move the lock arm through its full travel. It should move smoothly without binding.
• Switch testing: Use a multimeter to test the lock position switches for proper continuity in locked and unlocked positions. Replace the lock assembly if switches fail.
• Wiring and board: Inspect wiring from the lock assembly to the EOC. If wiring and lock assembly are good, the EOC lock relay or logic may be defective and require replacement.

Warning: Do not force the door open during a self-clean cycle; allow the oven to cool and unlock normally or manually release the lock with power off.
