Dryer's Drum Doesn't Tumble

Although there are a number of reasons the dryer's drum won't tumble, the most common cause is a defective belt, particularly if the motor is running.

Belt

When the dryer's belt is worn or broken it won't be able to turn the drum. You'll need to replace the belt to get your dryer working again. Be sure you purchase the correct belt for your model. Then place the belt on the drum where to old belt had been and wind it onto the idler pulley and the motor pulley.

If the belt isn't broken or worn, check that it's in place on the drum and is properly fed thru the pulley configuration. The problem may be as simple as the belt being out of place. 

*If you need to replace your dryer's belt, it's a best practice to also install a new idler pulley at the same time. As the idler pulley wears out, it places unnecessary stress on the belt which shortens it's service life. The original problem may not have been the belt, but rather the idler pulley. Failure to change the idler pulley may mean you end up replacing your new belt much sooner than you expected. 

Drum Support Rollers

The dryer drum sits on top of drum support rollers and over time the rollers become worn and need to be replaced. Although this isn't too difficult of a repair, you will need to remove the drum in order to reach the rollers.

Seized Motor or Support Parts

If the belt or idler pulley is the issue the motor should be running. However, when the dryer is on and you hear a buzzing or no sound at all there's a good chance that your motor has seized. It's possible that you'll be able to replace the motor's start capacitor, but don't be surprised if you need a new motor!

How to Test for a Seized Motor (and other Part Issues):

  1. First, remove the belt and inspect the blower fan housing for blockages.
  2. Then, hand turn the motor shaft. If it doesn't turn or it's extremely difficult, there's a good chance it is has seized and you'll need a new motor.
  3. If the motor turns with ease, turn ON the motor and allow it to run for a few seconds before installing a new belt.
  4. If the motor appears to run fine, the problem may be with the drum rollers or idler pulley.
  5. Next, rotate the drum by hand. If it's difficult to turn, the problem is most likely the idler pulley, drum rollers or drum glides.
  6. You can test each of these parts or simply replace them all since you have the dryer open.
