how to test a defrost temperature sensor

How do you test a refrigerator defrost sensor?

The defrost sensor—also called a defrost bi-metal thermostat—shuts off the defrost heater if the heater gets hot enough to damage the evaporator. If the defrost sensor fails, the heating element doesn't turn on, and frost builds up on the evaporator resulting in warm temperatures in the refrigerator. Also, why does my fridge not turn off? If your refrigerator is running too long, it could ...
