LG Refrigerator Er CF Error Code
Condenser fan error on LG refrigerators.

Compatible models
LG lists CF for both digital and analog display models. On analog models it specifically means no signal is coming from the fan motor.

How to fix LG Er CF
Reset the power
Unplug the fridge for about 5 minutes, then plug it back in.
Give it room to breathe
Make sure nothing is pushed against the back of the fridge or blocking the lower front grille, such as bags, boxes or a rug. Clear the area so air moves freely.
When to call a technician
LG lists Er CF as a repair code. If it comes back after a reset, book service; the fan sits next to high-voltage and sealed-system parts that only a technician should handle.
