LG Range (Gas) 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

  3. 3

  4. 4
