— LG USA, [LG Refrigerator] Digital and Analog Error Codes. Codes vary by model: check your refrigerator’s own manual.
Next to FU in LG’s table: FS (fault with the freezer temperature sensor) and IF (malfunction in the ice maker fan).
Safety: If it smells like burning, sparks, or trips the breaker, switch it off at the breaker and leave it off until it is checked.
At least TODAY. fixRAgent treats this code as needing attention today. It points at water where it should not be, overheating, a combustion or ignition safety shutdown, food that may be warming, or a wiring problem. This is fixRAgent’s reading, not the manufacturer’s. A photo can raise it — water near wiring, scorch marks, a gas smell — but a code never lowers what the photo shows.
Appliance repair. Have the model and serial numbers from the label ready — a photo of the label works.
Check whether your model is under a safety recall on the U.S. Consumer Product Safety Commission’s site: cpsc.gov/Recalls. Your owner’s manual is on LG’s support site; search it with the model number from the label.
