This is an evaporator that is located inside many refrigerators. It has a part to play in ensuring the items inside the appliance stay cold. When the refrigerator turns from a liquid into a gas through evaporation, it cools the area nearby and makes it ideal for storing perishable food items. The evaporator pulls air from the refrigerator and blows it over the coils to keep it at the appropriate temperature. There are several signs that the evaporator is damaged or no longer working correctly. Sometimes it will make a chirping or squealing noise. It may cause the refrigerator to be too warm, which may cause issues with the food items inside. Frost buildup on the coils is also a bad sign. If the evaporator is damaged, it needs to be replaced. Unplug the refrigerator and remove the panel over the evaporator. Remove the clamps to uninstall the part. The new part can be installed in the same place. Make sure to test before use.This evaporator is made to be compatible with Maytag, Whirlpool, KitchenAid, and Kenmore refrigerators. It is directly sourced from the manufacturer and sold on an individual basis. This is an authentic OEM replacement component.
