Whirlpool WP4-35940-001 Refrigerator Thermostat

The Whirlpool WP4-35940-001 Refrigerator Thermostat has become a crucial part which assures your Whirlpool refrigerator stays a consistent temperature. It acts as the cooling system's intellect, controlling the compressor and fan to ensure proper food preservation. This refrigerator thermostat monitors internal temperature through a capillary tube and a refrigerant-filled bulb. As the temperature increases, the refrigerant expands and presses across a diaphragm within the thermostat. This triggers an electrical switch, turning down the compressor and allowing the temperature to decrease. Once the temperature needed is reached, the electrical switch turns again, activating the compressor to maintain the atmosphere cool. This ongoing cycle preserves your food fresh and prevents spoiling.
