LG Range (Gas) F17 error code

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

The F17 error means your LG range detected a problem with the convection fan. The convection fan circulates hot air evenly throughout the oven cavity during convection cooking to ensure consistent results. When it cannot operate correctly the oven stops the convection function to prevent uneven cooking or overheating. A reset clears it in some cases but if F17 keeps returning the convection fan motor will need to be inspected and replaced by a technician.

Common causes

  • Convection fan motor has malfunctioned or failed
  • Fan blade is obstructed by debris or a foreign object
  • Wiring connection to the convection fan motor is loose or damaged
  • Temporary electronic glitch causing a false fan error
