LG Refrigerator Error Code R-FAN ERROR

The R-FAN ERROR indicates a problem with the refrigerator compartment fan motor circuit. The main control board has detected a contact failure on the feedback signal line, a broken motor wire, or an internal motor defect. This fan circulates cold air throughout the refrigerator section, and a fault here can cause uneven or inadequate cooling.

It is not recommended to continue using the refrigerator without addressing this error. The R-fan motor circulates air throughout the refrigerator compartment, and if it has stopped operating, food temperatures may rise into unsafe ranges relatively quickly. Check your internal temperature with a thermometer and move perishables if the fridge is not maintaining safe temperatures.

Repair costs vary depending on the cause. If the fix is simply reseating a loose connector, there is no parts cost involved. A replacement R-fan motor typically costs between $30 and $80 for the part alone. If the main PCB is the cause, board replacement can range from $100 to $250 or more for the part. Adding professional labor will increase the total cost by $75 to $200 depending on your area.

Some causes of this error are DIY-friendly. Start by checking the wiring harness and connectors between the main PCB and the fan motor for loose, corroded, or damaged connections. If the connectors are secure and the wiring is intact, testing voltage at CN 74 pins 5 and 7 requires a multimeter and basic electrical knowledge. Replacing the fan motor is a moderate-difficulty repair that many experienced DIYers can complete.

A power reset may temporarily clear the error display, but the code will return if the underlying fault is still present. Because this error is tied to a hardware condition such as a wiring fault or motor failure, the error will not be permanently resolved until the root cause is diagnosed and repaired.
