Error codeF19
ApplianceRange
Heating is the problem F19 describes: LG’s manual calls it an oven heating error and applies it to ranges with an oven, with no series restriction.
What you can do
Press CLEAR/OFF and return to the function you first chose. Seeing F19 again means resetting the power: breaker off, a pause of 30 seconds, breaker on.
Per the manual, a problem that continues requires service for the unit.
San Francisco households can call (415) 223-7887 to arrange LG range and oven repair. Bring up F19 and the model number, and tell us how the breaker reset went.
Model compatibility: LG reuses codes across series and model years, so F19 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
