LG Refrigerator Error Code E rF

E rF indicates that the refrigerator compartment BLDC fan motor is not operating correctly. The control board expects to receive a feedback signal confirming the fan is spinning, and if that signal does not arrive within 65 seconds, the error is triggered. Common causes include ice blocking the fan blade, a failed motor, or a wiring problem. The fan is critical for circulating cold air in the fresh food section.

A reset may temporarily clear the code, but it will return if the underlying problem is not resolved. Resetting is actually the recommended first diagnostic step, followed by entering Test 1 Mode to observe fan behavior and check airflow. If the fan motor or wiring is faulty, the error will reappear within 65 seconds of the fan attempting to start.

Repair costs depend on the root cause. If only a wiring harness repair or ice clearing is needed, costs are minimal and may only involve a service call fee, typically in the range of $75 to $150. A replacement BLDC fan motor generally costs between $50 and $150 for the part, with labor adding to the total. A main control board replacement is the most expensive scenario, with parts and labor often ranging from $200 to $450 or more.

Some causes are DIY-friendly, such as clearing ice buildup from around the fan blade or reseating a loose wiring connector. However, replacing the BLDC fan motor or diagnosing a control board issue requires comfort with electrical testing, including checking voltage at specific connector pins. If you are not experienced with appliance wiring, it is safer to contact a qualified technician.

The E rF error is not a safety hazard in the traditional sense, but it does mean your refrigerator is not maintaining proper temperature in the fresh food compartment. This can lead to food spoilage relatively quickly if the fan is completely non-functional. Address the error promptly to prevent food loss and avoid potential strain on other components.
