LG Range (Electric) F3 error code

Difficulty: Hard · Cost: $100–$300 · Duration: 5m

The F3 error means your LG range detected a problem with the touch pad sensor — the touch-sensitive control panel used to operate the range. When a key fault is detected the range cannot accept inputs correctly and stops the current function. This can be caused by moisture, food residue on the touch pad, or a hardware fault. A circuit breaker reset clears it in some cases. If F3 keeps returning the touch pad will need professional inspection.

Common causes

Touch pad sensor key has malfunctioned or failed
Moisture or food residue on the touch pad causing a false key input
Temporary electronic glitch triggering a false sensor key error
Touch pad wiring is loose or damaged

How to fix it

1

Turn off the circuit breaker for the range and wait 30 seconds
2

Turn the circuit breaker back on and check if the error has cleared
3

If F3 persists after resetting check the touch pad surface for any moisture or food debris and clean it gently with a dry cloth
4

If F3 keeps returning the touch pad sensor needs inspection and replacement by a qualified technician
