This defrost thermostat is a temperature sensing mechanism used in freezers and refrigerators. The thermostat senses the rise in evaporator temperature during a defrost cycle and turns the defrost heater off once frost is melted from the coils. If the freezer is not defrosting, or the freezer section is too warm, it is best to replace the thermostat to fix the problem. The tools needed for this project are: 1/4 inch nut driver, flat blade screwdriver, needle nose pliers, wire strippers, and pair of wire nuts. Remember to unplug your appliance from the power source for safety and refer to the manual provided by the manufacturer for installation instructions.

This long harness thermistor kit is what helps monitor and regulate the temperature inside your refrigerator. It can be located in either the freezer compartment near the evaporator coils or in the fresh food compartment near the airflow channels, depending on the model. If you notice issues like excessive icing in the freezer, inadequate cooling in the refrigerator, temperature fluctuations, or error messages on the display panel, it indicates a potential problem with the thermistor. Since your fridge will not be able to maintain the desired temperature, this results in food spoilage, inefficient cooling, and potential damage to the cooling components. To replace the thermistor, disconnect it from the connector plug or wiring harness and remove any mounting brackets or clips using a screwdriver if necessary. Remember to consult your user manual to determine the required number of thermistors, as they are sold individually as OEM replacement parts.
