This thermostat is a critical component in the automatic defrost system, functioning as a thermal safety device that monitors the temperature of the evaporator coils during the defrost cycle.\u003c\/p\u003e\n\u003cp\u003eWhen the evaporator reaches the preset maximum temperature of 140°F (60°C), the bi-metal thermostat opens the circuit and cuts power to the defrost heater — preventing overheating and damage to the evaporator. It resets and closes again at 104°F (40°C), allowing the next defrost cycle to begin normally. When the thermostat fails, it can cause excessive frost buildup on the evaporator coils, poor cooling performance, or a heater that won't shut off — all resulting in the refrigerator failing to maintain proper temperatures.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c!-- Quick Answer --\u003e\n\u003cdiv class=\"pom-qa\"\u003e\n\u003cp class=\"pom-qa-label\"\u003eQuick Answer\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eXPARTCO DA47-00243K Refrigerator Defrost Thermostat\u003c\/strong\u003e fixes refrigerators with excessive frost buildup, a freezer that is too cold while the fridge is too warm, a heater that won't shut off, or a refrigerator that stops cooling.
