The refrigerator defrosts sensor-also known as the defrost bi-metal termination thermostat-trips when it detects that the temperature of the evaporator is getting hot enough that it might overheat. When the defrost sensor trips, it shut off power to the defrost heater. If the defrost sensor trips because it's not working correctly, frost builds up on the evaporator fins, eventually making the refrigerator and freezer not cool well. You can use a volt/ohmmeter to check the defrost sensor for continuity. Replace the defrost sensor if it shows no continuity at around 0 degrees .

Can a fridge work without a thermostat?
You can run a fridge without a thermostat. A thermostat is just an on/off switch for the compressor. When the temp reaches the point that you set it at, it goes one.
