Meaning
Some LG refrigerators report fan or sensor faults on the display.
Symptoms
Warm freezer, clicking, ice on the evaporator cover.
Possible causes
Ice-locked evaporator fan, failed sensor, heavy frost from a leaky gasket.
Safe checks
Unplug 10 minutes. Do not chip ice with knives. If frost returns quickly, book inspection.
When to call a technician
If the code returns after the safe checks, stop and request a technician. Error meanings can vary by model — read the sticker inside the door and the model’s manual.
