  • I don't believe the above answer is correct. This part is actually a bi-metallic switch. It is 'normally closed' ie. short-circuit (zero ohms) at room temperature, and is open circuit above 78 degrees C. I have just tested a brand new one, and that's how it worked. It is NOT a temperature dependent resistor(thermistor), which is what you might assume. It is simply a temperature activated switch. By Dave - Scotland - 10 December 2011

    Hi ornito, the thermostat will be open when below 78 degrees, and shut when higher than 78 degrees.
