LG Oven Error Code F10 — Door Locking System Failure (Upper Oven)
What this means
The F10 error code indicates the upper oven's door locking system failed during a self-clean cycle or when attempting to lock/unlock the oven door. The door lock motor or switch has not reached the expected position. This prevents the self-clean cycle from operating and may leave the door locked.
Step-by-step fix
2 stepsReset the oven
Press CLEAR/OFF. Turn off the circuit breaker for 30 seconds. Turn it back on and wait for the door lock motor to attempt to reset (you may hear a motor sound).
Do not force the door open if it is locked. The lock motor needs power to retract.
Check for obstructions
Make sure nothing is preventing the door latch from fully engaging. Wipe the latch mechanism clean.
When to call a professional
If the door lock motor or switch has failed, a technician can replace the lock assembly. If the door is stuck locked, a professional can safely release it.
