Display shows F13, often related to the oven door lock or self-clean cycle.

Safety first: Disconnect power. The lock mechanism can move suddenly; keep hands clear.

• Check door alignment: Ensure the oven door closes fully and is not misaligned or sagging, which can prevent the lock from engaging.
• Inspect lock assembly: Remove the top or rear panel (depending on model) to access the lock motor and linkage. Look for broken plastic arms or disconnected rods.
• Test lock motor: With power disconnected, test the motor coil for continuity. An open reading indicates a failed motor.
• Check lock switches: Use a multimeter to verify that the lock position switches change state when the lock is manually moved.
• Replace lock assembly: If any component is defective, replace the complete door lock motor assembly for reliability.
