LG Air Conditioner Error Code E475

E475 indicates a fault with the second BLDC fan motor in the outdoor unit. The control board has detected that Fan 2 is not operating correctly, either because it is not spinning, is obstructed, or is not returning the expected feedback signal. The system shuts down to prevent damage to other components.

No. The system typically locks out operation when E475 is triggered to prevent further damage. Attempting to bypass the lockout or repeatedly restarting the unit without addressing the underlying fault could damage the control board or other components. Leave the unit off until the fault is properly diagnosed and repaired.

Repair costs depend on what component has failed. If the issue is simply a debris obstruction or a loose connector, you may only pay a service call fee, typically in the range of $75 to $150. A replacement BLDC outdoor fan motor generally costs between $100 and $300 for the part alone, while an outdoor control board can range from $150 to $500 or more depending on the model, plus labor.

Some basic checks are safe for a homeowner, such as turning off power and inspecting the outdoor unit fan for visible debris or obstructions, and checking that no wiring connectors appear loose or disconnected. However, diagnosing a failed BLDC motor or a faulty control board requires electrical testing and should be handled by a qualified technician. Working inside the outdoor unit with power on carries serious shock risk.

A power reset may temporarily clear the error display, but if the underlying fault with Fan 2 still exists, the error will return quickly once the unit attempts to operate. A reset is only effective as a long-term solution after the root cause, such as a cleared obstruction or reseated connector, has been resolved.
