4388574 - Whirlpool Refrigerator Evaporator

This Whirlpool Refrigerator Evaporator (4388574) is a genuine part designed specifically for Whirlpool refrigerators, but it's also compatible with select KitchenAid models. The evaporator is the heart of the cooling system, housing a refrigerant that evaporates to absorb heat from inside the refrigerator. This evaporator looks somewhat like a radiator and functions by changing the liquid refrigerant into a gas. This phase change absorbs heat, making the evaporator cold to the touch and ensuring that your appliance maintains a low internal temperature to keep food fresh. Additionally, the fan inside the freezer circulates this cooled air to the freezer and fresh food sections, stabilizing temperatures throughout the appliance.

If you've noticed your refrigerator struggling to maintain a cool enough temperature, or an increase in your energy bill that you suspect is related to your fridge running more often to keep cool, it could indicate a faulty evaporator. Signs that the evaporator may be failing include inadequate cooling, leading to food spoilage, and increased energy consumption due to the appliance working harder to maintain the proper temperature.

Before making your purchase, please confirm your device's model number to ensure this part is the right fit for your refrigerator.
