Dryer: Why is my dryer making a rattling noise?

The dryer making rattling noise while tumbling often means that a hard object is clanging around inside the drum — the zipper on a sweatshirt, change left in a pocket, your phone.

If the contents of the drum check out okay, a bad drum support roller could be causing a thumping noise. A damaged idler pulley, idler pulley bracket or idler pulley tension spring could also cause a loud noise such as banging or squealing. If you hear the dryer making a loud rattling noise while tumbling, check the blower fan blade. A scraping noise can indicate damage to the drum glide bearing or felt drum seal. Suspect the drive motor if you hear a buzzing or whining noise while the dryer runs.

JC-DRY-Replace-or-repair-the-dryer-drive-motor

Replace or repair the dryer drive motor

The drive motor rotates the motor shaft, which in turn rotates the idler pulley, which rotates the drive belt that's wrapped around the dryer drum. The motion of these components causes the drum to rotate during the cycle. The drive motor also rotates the blower fan blade on most dryers.

A failing drive motor may shut off in the middle of a cycle. Some dryers will restart automatically when the motor cools, but others require that you restart them. Replace the drive motor if it overheats.

The wire harness connections on the motor can be repaired, but the internal components on the motor cannot. If the drive motor doesn't run when voltage is applied to it, replace the drive motor.

A felt seal around the front and the back of the dryer drum prevents warmed air from escaping while allowing the drum to glide smoothly across the contact surfaces on the rear bulkhead panel and the front panel in the dryer. You can physically inspect the seal from inside the dryer drum by unplugging the dryer and lifting the top panel to examine the felt seal more closely. If the felt seal is damaged, replace it.
