Display shows F9, oven door may not lock/unlock during self-clean or door lock icon flashes.

Safety first: Turn off power at the breaker before attempting to access the door lock mechanism.

• Cancel self-clean: If the error occurred during self-clean, press Cancel/Off and wait several minutes to see if the lock retracts after cooling.
• Check door alignment: Ensure the oven door closes squarely and the latch engages the strike plate. Adjust hinges if the door is sagging.
• Access lock assembly: Remove the top panel or rear panel (depending on model) to access the door lock motor and latch assembly. Inspect for broken plastic parts, bent linkage, or disconnected rods.
• Test lock motor: With power disconnected, check continuity of the lock motor and lock switch. An open motor or switch requires replacement of the lock assembly.
• Manual release: Some models have a manual lock release accessible from the top or rear. Use it to unlock the door temporarily, then replace the faulty lock mechanism.

When to call a technician: If you cannot access the lock assembly without removing the range from cabinetry, or if wiring to the lock is damaged, professional service is recommended.
