What F10
actually means.
LG lists F10 for a door locking system failure on the upper oven and F20 for the same on the lower oven. The lock is needed for self-clean, so the code often appears when a clean starts or ends.

What to do when F10 shows on the rangeKind of codeDoor and lock
The oven door lock did not move to where the control sent it, or its switch reported the wrong position. It shows up most around self-clean; the latch, its switches, the hinges and how squarely the door closes are looked at before the lock motor is changed.

An oven door that will not close, sits crooked, leaks heat, or stays locked after self-clean, traced to the hinges, the gasket, the glass or the lock.
Shows up asRange Self-Clean Problems
The self-clean cycle will not start, stops partway, leaves the door locked, smokes heavily, or leaves the oven dead afterward.

F10 indicates an Door Locking System Failure (Upper Oven).
