This DIY repair guide explains how to replace the condenser fan on a window air conditioner. The condenser fan blows air across the condenser coil at the back of the air conditioner to cool the condenser coil. If the condenser fan motor bearings wear out, the fan may squeal or stop running; as a result, the air conditioner won't cool well or won't cool at all. Replace a worn condenser fan using the manufacturer-approved window air conditioner part.
Follow these steps to replace the condenser fan in Kenmore, Frigidaire, Crosley and LG window air conditioners.
