What to do if my LG Air Conditioner fan motor runs intermittently?

M
Mark RussellAug 26, 2025
If the fan motor in your LG Air Conditioner runs intermittently because it revolves on overload: * Check the voltage against the specified limits. If it's not within limits, consult an electrician. * Test the capacitor. * Check the bearings. Also, verify that the fan blade rotates freely. If not, replace the fan motor. Pay attention to any change from high speed to low speed. If the speed does not change, replace the motor.
