If you have frost building up in your freezer, or the temperature in your fridge is running too warm, there may be an issue with the defrost thermostat. This thermostat sits on the top of the evaporator and protects it from overheating when the defrost cycle is running. It does this by regulating the temperature in your appliance, and should shut off the heater once the frost has melted off the coils. If you need a new thermostat, this is a genuine OEM replacement part. Please be sure to disconnect the power supply to your fridge before beginning this repair.

No matter where I set the control the freezer keeps running and maintains temperature at approximately 12-15 degrees
For model number 253.28262801
Hello Charlie, Thank you for the question. We suggest testing the Defrost Thermostat with a Multimeter. The best way to do this is to remove the thermostat from the refrigerator so you can control the temperature of the sensor. You can let the sensor warm up to room temperature. With the sensor warmed up to room temperature the sensor should read approximately 6.2K Ohms at 68°F. With the thermistor submerged is a glass full of ice water, the sensor should be very close to 32°F which should read approximately 16.3K Ohms. If the values that you are getting are far off from these readings, then the sensor is bad and should be replaced. We hope this helps!
