FAQs

If your refrigerator is not cooling properly, you may notice frost buildup on the back wall of the freezer, ice forming on the evaporator coils, or the refrigerator section becoming too warm. These symptoms often suggest the defrost cycle is not initiating, which is frequently caused by a faulty bimetal thermostat.
This part is compatible with refrigerators from Whirlpool, Kenmore, Amana, Roper, Estate, Crosley, Inglis, Jenn-Air, KitchenAid, Maytag, and Magic Chef. It directly replaces OEM part numbers WPW10225581, W10225581, PS11750673, AP6017375, 2188824, 2321799, W10260437, 2149849, 2161331, 2176066, 2196155, 2266066, 2266067, 2315504, 2317087, 2319914, 2321802, and 4387498.
Replacing the defrost thermostat is a moderate repair that typically takes 30 to 60 minutes. You will need basic tools, including a screwdriver and a nut driver. You must unplug the refrigerator and remove the food and shelving to access the evaporator cover inside the freezer. Because the wires are often spliced into the existing harness, you may need wire strippers and crimp connectors or heat-shrink tubing to ensure a secure, moisture-resistant connection.
Before installing the new part, inspect the evaporator coils for excessive ice buildup. If the coils are completely encased in ice, you should manually defrost them using a hair dryer or by leaving the unit unplugged with the doors open for several hours. This ensures the new thermostat can make proper contact with the cold surface and function correctly once the system is powered back on.
The defrost thermostat is a safety device designed to open the circuit when it senses the evaporator coils have reached a specific temperature. Over time, the internal bimetal switch can wear out or become stuck due to constant exposure to extreme temperature fluctuations and moisture within the freezer environment, eventually preventing the defrost heater from turning on.
