5304521781 - Electrolux Refrigerator Thermostat

This Electrolux Refrigerator Thermostat (5304521781) is a genuine part for Electrolux and Frigidaire refrigerators. It acts as a precise on/off switch that activates refrigeration system components like the compressor, condenser fan, evaporator fan, and others to maintain programmed temperature ranges in the fresh food and freezer compartments. Additionally, it controls a separate defrost thermostat mounted near the evaporator to prevent excessive heating of the coils during defrost cycles. This thermostat utilizes a sensor bulb and capillary tube connected to the evaporator outlet to measure cold air temperature, ensuring your appliance maintains precise temperature control by cycling the refrigeration system in response to changes in air temperature measured at the evaporator. Common symptoms indicating this thermostat may be failing include inconsistent temperatures in the refrigerator compartments or the appliance running too frequently. Before purchasing, kindly verify your device's model number for compatibility.
