Magic Chef oven displays F8, often related to door lock or self-clean cycle; door may remain locked.

Safety first: Turn off power at the breaker. Allow the oven to cool completely if it was in self-clean.

• Try a power reset: After cooling, turn power off for 5 minutes, then restore. Sometimes the lock will cycle and clear the error.
• Listen for lock motor: Start a self-clean or cancel it and listen for the lock motor running. No sound may indicate a failed lock motor or no power to it.
• Inspect lock assembly: Access the door lock from the top or rear (varies by model). Check the lock motor, linkage, and micro-switches for binding, broken plastic, or burnt connectors.
• Test lock switches: With a multimeter, verify that the lock switches change state (open/closed) when the lock arm moves. Replace the door lock motor and switch assembly if defective.
• Check wiring to EOC: Ensure the harness from the lock assembly to the EOC is intact and firmly connected.

When to call a technician: If the door is stuck locked and you cannot access the lock mechanism safely, contact a professional.
