The refrigerator defrosts sensor also known as a defrost bimetal terminal thermostat trips when it detects that the temperature of the evaporator is getting hot enough that it may overheat. When the defrost sensor trips, it turns off power to the defrost heater. If the defrost sensor trips because it's not working properly, frost builds up on the evaporator fins, eventually preventing refrigerators and freezers from cooling well. You can check the continuity of the defrost sensor with a volt/ohmmeter.
The PL002 3285A Refrigerator Defrost Thermostat clips onto the evaporator and protects the evaporator from overheating during the defrost cycle. If your refrigerator won't defrost, you can test both the thermostat and heater to find out which part is at fault.

What is a Bi-metal defrost thermostat?
Defrost bimetal thermostats prevent the harmful buildup of frost on refrigerator and freezer evaporators. These devices trigger a defrost heater that stops frost from forming on refrigeration evaporator coils, which helps keep the refrigerator and freezer running efficiently.
