Customer Questions and Answers for Refrigerator Condenser Fan Motor Kit by Whirlpool

Vicki, The condenser fan serves two purposes, it circulates air through the condenser assembly, this cools the hot refrigerant that is circulating through the condenser coils " All refrigerators cool by removing heat from the cabinet rather than pumping in cool air. In a conventional refrigerator, liquid refrigerant enters the evaporator and vaporizes (boils) due to the low pressure, creating a very cold surface which removes heat from inside the cabinet. This causes the refrigerant to boil (evaporate) into a vapor state and be drawn into the compressor. The compressor pressurizes the vapor and pumps it into the condenser. The hot vapor in the condenser gives off the heat into the room. As the vapor cools, it condenses back into a liquid and returns to the evaporator to start the process over again." At the same time, it is also cooling the compressor. The hotter the refrigerant, the less efficient it is, and you will notice a loss of coolig in the freezer and refrigerator. You'll want to change that fan motor as soon as possible.
