What the F-10 error code actually means

Your LG oven is displaying F-10 because it tried to lock the oven door at the start of a self-clean cycle but could not confirm the door actually locked. This is a safety feature that stops the clean cycle from running with an unsecured door. The problem is usually a loose wire connection or a worn part in the door locking mechanism.

Questions people ask about F-10

What does F-10 mean on a LG oven?
F-10 on an LG oven signals an upper oven door lock failure. The error appears when the door lock switch does not confirm a successful lock after the door locking motor completes two rotations during the start of a self-clean cycle. The oven's control board halts the self-clean process as a safety measure when this confirmation is missing. The fault is most often traced to loose wiring terminals, a defective micro switch, or a worn door locking motor.
Is it safe to use my LG oven when F-10 is displayed?
F-10 specifically disables the self-clean function because the door lock system cannot be confirmed. Normal bake and broil functions may still operate, but you should not attempt to run a self-clean cycle until the fault is resolved. Continuing to use the oven for regular cooking while the lock mechanism is faulty carries some risk, so it is best to have the issue diagnosed and repaired promptly.
How much does it cost to repair an LG oven F-10 error?
Repair costs depend on which component has failed. A replacement door lock micro switch typically costs between $15 and $50 for the part alone, while a door locking motor assembly generally runs between $40 and $120. If professional labor is required, expect to add $100 to $200 or more in service fees depending on your location and the technician's rates. Resolving the fault through a simple terminal reconnection costs nothing beyond your time.
Can I fix the F-10 error on my LG oven myself?
Some causes of F-10 can be addressed by a confident DIYer. After disconnecting power, checking and reseating loose terminal connections at the micro switch and door locking motor requires no special tools and may resolve the error. Replacing the micro switch or door locking motor involves more disassembly and basic electrical testing, which is within reach for someone comfortable working on appliances. If the control board is suspected, professional service is recommended.
Will resetting my LG oven clear the F-10 error code?
Disconnecting power for several minutes will clear the F-10 code from the display, but the error will return the next time a self-clean cycle is started if the underlying fault has not been corrected. A reset is a useful first step to confirm whether the issue is intermittent, such as a briefly loose connector, but it is not a permanent fix for a failed switch or motor.
