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.
