LG Range (Electric) F11 error code

Difficulty: Hard · Cost: $100–$350 · Duration: 5m

The F11 error means your LG range detected a communication failure between internal components — typically between the main control board and another part of the range such as the display board or a secondary control module. When this communication breaks down the range cannot operate normally and stops the current function. A reset clears it in some cases but if F11 keeps returning the control board or wiring will need to be inspected by a technician.

Common causes

Communication fault between the main control board and another internal component
Wiring harness between control components is loose or damaged
Main control board or display board has malfunctioned
Temporary electronic glitch causing a false communication error

How to fix it
