LG Range (Electric) F56 error code

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

The F56 error means your LG range detected a heating problem with the built-in griddle. The griddle was unable to reach or maintain the required temperature during operation. This can be caused by a faulty griddle heating element or a control board issue affecting the griddle heating circuit. A circuit breaker reset clears it in some cases but if F56 keeps returning the griddle heating components will need to be inspected and replaced by a technician.

Common causes

  • Griddle heating element has malfunctioned or failed
  • Control board fault affecting the griddle heating circuit
  • Wiring to the griddle heating element is loose or damaged
  • Temporary electronic glitch causing a false heating error

  2. 2
