Dryer thermal fuse located on the blower housing. If the dryer overheats, the thermal fuse blows cutting off power to the motor or the heating system. When the fuse is bad the dryer won't start or will run but not heat. The thermal fuse cannot be reset. Fuses often blow due to a clogged dryer vent.
Dryer drum drive belt. The belt is flat, 92-1/4 inches long, 1/4 inch wide and has 4 ribs and 3 grooves. It replaces many other belts, including some with 5 ribs and 4 grooves. If the drum does not turn, but you can hear the motor running then there is a good chance the belt has broken.
Dryer door switch assembly. If the dryer does not start then the door switch could be defective. This switch also replaces the two wire switch.
