GE oven displays F9 and the door may remain locked after self-clean or will not lock

Safety first: Turn off power at the breaker. The door and interior may still be very hot after self-clean; allow to cool completely.

• Try a power reset: After cooling, turn power off for 5 minutes, then restore. Attempt to start and cancel a clean cycle to see if the lock resets.
• Inspect latch mechanism: Remove the range back panel (for freestanding) or top panel (for wall ovens) to access the door lock motor and latch. Check for bent linkage, broken plastic pieces, or obstructions.
• Test lock motor: With power off, disconnect the lock motor connector and measure coil resistance (typically tens to hundreds of ohms). An open circuit indicates a failed motor.
• Check lock switches: Many GE locks have position switches. Test continuity with the latch in locked and unlocked positions. Replace the lock assembly if switches do not change state.
• Manual release: If the door is stuck locked, locate the manual release lever or rod near the lock assembly and move it to unlock the door.
