LG Range (Gas) F6 error code

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

The F6 error means your LG range detected a heating problem in the upper oven. The upper oven was unable to reach or maintain the required temperature during operation. This 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 F6 keeps returning the heating components will need to be inspected and replaced by a technician.

  • Temporary electronic glitch causing a false heating error
