Quick answer
rF reports a refrigerator fan fault. Frost can be the cause, so the manual starts with a defrost; kimchi models have their own 24-hour thaw.
Model compatibility: LG reuses codes across series and model years, so rF may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
rF is a refrigerator fan fault, often caused by frost buildup around the fan motor.
The rF code means the refrigerator fan is not working as it should. That fan circulates cold air through the refrigerator. If it is blocked, the compressor overworks to hold the temperature, the inside warms up and performance falls. The refrigerator carries a sensor that detects a blocked fan.
Standard LG refrigerators
LG’s list describes rF as an abnormality in the fan motor that may be due to frost buildup. Its manual defrost goes like this:
Unplug the unit and take out all food and the ice from the ice bin.
Leave the doors open for at least 8 hours so the frost melts.
Keep towels in and around the unit to soak up meltwater.
Wipe any remaining moisture from the refrigerator and freezer with a dry towel.
Plug it back in and allow 24 to 48 hours for normal operation to return.
Afterwards, check that the vents inside are not blocked, that the cabinet and doors are level, and that both doors close completely.
Kimchi refrigerators
On a kimchi model, rF (shown as Er rF or E rF) means ice or frost is blocking the fan on the right side of the upper compartment. Move the food out, put dry towels down, unplug the unit and open all doors for at least 24 hours, dry everything, and plug it in again. A hair dryer is not safe for this job.

Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
