LG Range Error Code F10

The F10 code on an LG range indicates a door lock failure. The oven attempted to lock the door by running the lock motor, but after the motor completed two rotations, the door lock switch did not confirm that the latch had engaged. The oven halts the operation and displays F10 as a safety response. The fault points to a problem in the lock motor, the micro switch, or the wiring connecting these components.

Normal baking and cooking functions may still operate while the F10 code is present, but you should not attempt to run a self-clean cycle until the door lock issue is resolved. A malfunctioning door lock means the oven cannot safely contain the extremely high temperatures used during self-cleaning. Address the fault before using the self-clean feature.

Repair costs vary depending on the failed component. A replacement door lock motor or micro switch typically costs in the range of $20 to $80 for the part alone. If a technician performs the repair, expect to add a service call fee and labor, bringing the total to a range of $100 to $250 or more. A defective main control board is the most expensive scenario, with board costs ranging from $150 to $350 or higher depending on the model.

A knowledgeable DIYer can handle many of the diagnostic steps, including checking wiring connections, testing the lock motor resistance with a multimeter (looking for approximately 2.6 kΩ), and testing micro switch continuity. Replacing the lock motor or micro switch is a manageable repair if you are comfortable working with appliance wiring. If the control board is suspected, professional diagnosis is recommended to avoid purchasing an unnecessary part.

Disconnecting the oven from power for a few minutes may temporarily clear the F10 code, but the fault will return as soon as the oven attempts to lock the door again if the underlying problem is not corrected. A reset is useful for confirming whether the error was a one-time communication glitch, but a recurring F10 code requires physical inspection and repair of the lock motor, micro switch, or wiring.
