Quick answer
CF on an LG refrigerator is a condenser fan fault, from a blocked fan or no fan signal.
Model compatibility: LG reuses codes across series and model years, so CF 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
Condenser fan fault (blocked fan or no fan signal).
CF on an LG refrigerator points to a fault with the cooling fan. This fan cools the condenser so the refrigerant can condense. The refrigerator has a sensor that detects when the fan is blocked, and the manual also describes a case where no signal is detected from the fan motor.
Why it matters
With a blocked fan, the compressor overworks to hold the temperature. The internal temperature then rises and performance drops.
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.
