Whirlpool WP4-35940-001 Thermostat for Refrigerator

The Whirlpool Thermostat regulates the refrigerator’s internal temperature. It monitors temperature changes and controls compressor operation to keep the cooling environment within the desired range.

The Thermostat uses a capillary tube connected to a refrigerant-filled bulb. As the temperature rises, the refrigerant expands and applies pressure to a diaphragm inside the thermostat.

When temperature changes activate the thermostat mechanism, an electrical switch controls compressor operation. The compressor is turned off as the temperature drops and reactivated when the desired temperature is reached.

Yes. The Whirlpool serves as a replacement thermostat for compatible refrigerator and freezer models. It restores the temperature-control function handled by the thermostat.

The part is listed for Amana AC101KW-P1317802WW, AQC0901TRW03, AZC31T15DW00, and MQC1552TEW00 freezer models.

As the temperature rises, the refrigerant inside the bulb expands. The resulting pressure moves the thermostat diaphragm, which activates the electrical switch involved in compressor control.
