Reading the range display

On a range or oven the fault appears on the clock or oven display, often with a beep. Press Cancel or Clear once to silence it, and write the code down first. LG codes are short letter pairs; a capital O differs from a zero.

LG appliances show short alphabetic codes (OE, IE, UE on washers, Er plus letters on refrigerators) and, on ThinQ models, a Smart Diagnosis option. LG also builds many Kenmore Elite units. The codes apply to model numbers such as LDF7774ST, LDT5678SS and DLEX3900B; check the label on your unit to confirm yours.

What causes F3

How to fix it

  1. Switch the unit off at the control and try the function again.
  2. If the code comes back, turn the range's circuit breaker off, wait 30 seconds, and switch it back on.
  3. Wipe the panel clean and dry, and press no keys while power restarts.
  4. Run the function once more and watch whether the code returns.
  5. If the code persists or you cannot perform the check, schedule a repair; most of these faults need a technician.
