LG Refrigerator Error Code F-FAN

F-FAN indicates that the freezer fan motor, a brushless DC type, has not produced a valid signal for more than 115 seconds. The control board detects this absence of feedback and triggers the fault code. The cause can be a failed motor, a wiring connection problem, or a shorted or open cable conductor. This fan is critical for circulating cold air, so the error often coincides with warming temperatures inside the unit.

A power reset may temporarily clear the display, but the code will return if the underlying fault is not resolved. Because the error triggers after 115 seconds of no motor signal, the control board will detect the same condition again once the unit restarts. A reset alone is not a fix and should only be used as part of the diagnostic process to observe whether the fault reappears.

Repair costs vary depending on the root cause. If only a connector needs reseating or ice needs to be cleared, costs may be limited to a service call fee, typically in the range of $75 to $150. If the BLDC fan motor itself needs replacement, parts plus labor can bring the total to roughly $150 to $350 depending on the model and local labor rates. Wiring harness repairs fall somewhere in between depending on the extent of the damage.

Some causes are DIY-friendly, particularly ice blockages and loose connectors. Start by turning off the refrigerator, removing the freezer fan grille, and manually checking whether the blade spins freely. If ice is blocking the fan, a manual defrost may resolve the issue. If the motor feels seized or the wiring is damaged, motor replacement or cable repair is required and may be better handled by a qualified technician.

Running the refrigerator with an active F-FAN error is not recommended for food safety. Without the freezer fan circulating air from the evaporator, both the freezer and fresh food compartments will lose their ability to maintain safe temperatures. Food spoilage can occur relatively quickly, especially in warmer ambient conditions. It is best to address the fault promptly or transfer perishables to another unit in the meantime.
