LG Range (Electric) F9 error code

Difficulty: Hard · Cost: $80–$250 · Duration: 5m

The F9 error means your LG range detected that the upper oven is not reaching or maintaining the correct temperature during operation. This is similar to the F6 error but represents a different heating fault condition in the upper oven. It can be caused by a faulty heating element, a damaged bake or broil element, or a control board issue. A reset clears it in some cases but if F9 keeps returning the heating components will need to be inspected and replaced by a technician.

Common causes

Upper oven heating element has malfunctioned or is not generating enough heat
Bake or broil element is partially damaged reducing heating performance
Control board fault affecting the upper oven temperature regulation
Temporary electronic glitch causing a false heating error
