    To answer your question they have a bi-metal disc which is an overload. If the area around the element gets to hot for then the overload will trip and turn off the element. Once cooled down then the overload closes and the element comes back on.

    Heating elements are made of whats called NiChrome. They are designed and engineered to be heated to several hundred degrees Fahrenheit in some cases.

    The ASME has dictated that a certain design element can only be used in certain situations and/or certain appliances/equipment.

    To answer your question: these elements are designed to be heated & cooled many thousands of times, but eventually they get brittle and break the circuit at some point.

    (ed) the other poster is only half right; the overload is for amperage only. the element is supplied a certain voltage and can only get as hot as the amperage allows.
