Most Frequent Causes for Dryer drum not turning

For the most accurate results, enter your model number.


Cause 1Drive 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.

Parts
Cause 2Drum 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.)

Parts
Cause 3Drum 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.

Parts
Cause 4Drum Bearing

The drum bearing supports the rear of the dryer drum. Over time, this bearing wears out. If the drum bearing is worn out, the dryer may not turn properly. To determine if the drum bearing is at fault, remove the dryer belt and try turning the drum by hand. If the drum rotates freely, the drum bearing is not likely worn out. If the drum makes squealing or grinding sounds when turned and/or is hard to turn, check the drum bearing and replace it if necessary.

Parts
Cause 5Drum Support 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.

Parts
Cause 6Drum Support Bearing

The drum bearing supports the rear of the dryer drum. Over time, this bearing wears out. If the drum bearing is worn out, it may put too much strain on the motor, causing the dryer to stop mid-cycle or not turn at all. To determine if the drum bearing is at fault, remove the dryer belt and try turning the drum by hand. If the drum rotates freely, it is unlikely that the drum bearing is worn out. If the drum makes squealing or grinding sounds when turned and/or is hard to turn, replace the drum bearing.

Parts
Cause 7Drum Slide, Glide, or Pad

One or more of the drum glides (also called slides) might be worn out. The drum glides are small plastic pieces that support the front of the dryer drum. As the drum rotates, it slides on these plastic pieces. Over time, the drum glides wear out. If the drum glides are worn out, the drum can start binding and put strain on the motor. If this happens, the motor shuts down, preventing the dryer from turning. To determine if the drum glides are worn out, inspect them for wear. If one or more of the glides are worn out, replace all of the glides as a set.

Parts
Cause 8Drive Motor

The drive motor turns the drum and the blower wheel to exhaust the air. First, check the motor to see if it makes a humming noise. If the motor still hums, remove the belt from the motor and check the blower wheel to ensure that it is not obstructed. Next, with the belt removed, try rotating the drum by hand. If the drum does not rotate freely, determine what is causing the drum to bind. If the drum turns freely and the blower wheel is clear of obstructions, the drive motor might be defective. If you suspect the motor is at fault, replace it.
