Cause 1
Drive Belt
The drive belt is a very long, slender belt that wraps all the way around the dryer drum, around a tension pulley, and then around the drive motor pulley. Over time, the belt can break from normal use. If the belt is broken, the dryer won’t turn. To quickly determine if the belt is broken, reach into the dryer and turn the drum by hand. If the drum spins very easily, the belt is likely broken. Next, inspect the belt to confirm that it is broken. If the belt is broken, replace it.
Cause 2
Drum Roller
Most dryers have two drum rollers on the rear of the drum, and some dryers have two more rollers supporting the front of the drum. The rollers must spin freely to work properly. If the drum rollers are worn out, the dryer won’t turn properly. To determine if the support rollers are worn out, remove the belt from the dryer and try turning the drum by hand. If the drum does not rotate freely, check the support rollers for wear. If one or more of the rollers are worn out, we recommend replacing all of the rollers at the same time as a preventative measure. (The roller shaft can often be reused if it is in good condition. Clean the shaft thoroughly before installing the new rollers.)
Cause 3
Drum Roller Axle
Most dryers have two drum support rollers on the rear of the drum, and some dryers have two more rollers supporting the front of the drum. The rollers must spin freely to work properly. Over time, the drum roller axles can wear out, causing the rollers to bind. If the rollers are worn out or start binding, the motor will get overloaded and the dryer won’t turn. To determine if the support rollers are worn out, remove the belt from the dryer and try turning the drum by hand. If the drum does not rotate freely, check the support rollers for wear. If the rollers spin freely without wobbling, they do not need to be replaced. If a roller wobbles and/or does not spin freely, we recommend replacing all of the axles and rollers as a preventative measure.
