Product review (5 stars): Dryer Thermostat and Overheat Fuse
The parts are not exactly the same size/shape of the original ones, but they have now been in place about 3 weeks and are working.

The Fuse/Overheat Switch is what blows. It is truly a fuse, when it goes, it does not reset itself, it must be replaced. Serviceman replaced it, and it blew again in about 3 days. I researched the problem and found the problem actually is the thermostat - it is letting the heat get much to hot before cycling off. It lets the heat go so high the Fuse blows. So, you have to replace both - the Fuse which is blown, and a new thermostat that will cycle off at a correct, lower temperature.

This setup is used on many different brands of dryers. Mine was a Kenmore, but it is used on several other name brands.
