Tap CLEAR/OFF to wipe the message.
Go back to the cooking function you wanted.
If the code shows once more, turn the breaker off, wait half a minute, and turn it on again.
Where it applies
The entry covers ranges and ovens in general, with no series named. LG says service is needed when the code stays or when the steps cannot be performed.
Similar-looking codes
F20 is the matching door lock failure, but for the lower oven.
Dial (415) 223-7887 to ask about LG range and oven repair in San Francisco or elsewhere in the Bay Area. It speeds things up to name F10, give the model number and say which reset steps you already ran.
Model compatibility: LG reuses codes across series and model years, so F10 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
