VERIFIED
A freezer fan that cannot spin sets off FF on an LG refrigerator. The panel may show FF, Er FF or E FF, and the fault is logged when the fan is blocked or reports no signal. Frost sitting on the fan is the usual reason.
Why a stalled fan matters
This fan pushes cold air around the freezer. Once it stops, the compressor overworks to keep the set temperature, the inside warms and performance falls. A sensor in the unit notices the blockage. LG lists the code for ordinary refrigerators and for kimchi refrigerators.
Defrosting a standard refrigerator
- Empty the unit: food goes to a spare refrigerator or a cooler, and the ice bin is cleared.
- Pull the plug.
- Swing both doors fully open and keep them that way for 8 hours or longer.
- Lay towels in and around the cabinet to take the meltwater, then dry the interior.
- Reconnect power. Normal cooling can need between 24 and 48 hours to return.
Models with LED-only panels light the 7°C, 3°C, 2°C and 1°C indicators for this code.
After the defrost
- Air vents inside should be clear.
- The cabinet should stand level.
- Both doors should shut all the way.
Frost along the freezer walls points to leveling and door alignment as the next things to look at. Clean walls mean the refrigerator needs repair service.
Kimchi refrigerator version
On a kimchi model the same code means ice or frost is keeping the internal cooling fan from turning. LG asks you to unplug the unit, open every door, wait at least 24 hours, dry the interior and then plug it back in.
Related codes
- dH: the defrost heater did not do its job.
- FS: the freezer temperature sensor has a fault.

LG refrigerator repair in San Francisco
If FF comes back after a full thaw, owners in San Francisco and around the Bay Area can phone (415) 223-7887. Mention whether the unit is a standard or kimchi model and quote the model number. The LG refrigerator repair overview covers the rest.
Model compatibility: LG reuses codes across series and model years, so FF (Er FF, E FF) may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
