Dryer drum belt, length 88.75" x width 1/4". If the drum does not turn, but you can hear the motor running then there is a good chance the belt has broken.
Dryer thermal limiter (or thermal fuse). May be located on the blower housing or element. If the dryer overheats, the thermal fuse blows to cut off power to the dryer. If the thermal fuse has blown, the dryer won't start. The thermal fuse cannot be reset--if the fuse has blown, it must be replaced
Dryer drum drive motor. Includes pulley for dryer drum drive belt. Other shaft has reverse threads for blower wheel. Common symptoms of a bad drive motor are:

-Dryer won't start
-Dryer won't turn at all
