Dryer Making a Loud Grinding or Squealing Noise: What It Means and How to Fix It

A dryer that suddenly starts grinding, squealing, or thumping is doing more than annoying you. The noise is an early warning, and what kind of noise you hear points to which part is wearing out. Knowing the difference helps you decide what to check and, just as important, when to stop running the machine before a small fix turns into a big one.

A squealing or screeching sound usually comes from a rotating part that has lost its lubrication or worn out. The most common offender is the idler pulley, which keeps tension on the drive belt. When its bearing wears, it squeals, and the sound tends to get worse with use. A worn drive belt can squeal too. If you ignore an idler pulley that is failing, the belt can eventually burn or snap, so a persistent squeal is worth addressing promptly.

A grinding noise is more serious. It often means the drum support rollers, the rear drum bearing, or the drum glides have worn down to the point where metal or hard plastic is rubbing where it should not. On many dryers, worn glides let the drum rub against the cabinet, producing a distinct grinding or scraping sound, sometimes with a squeal mixed in. Because grinding can damage other parts quickly and can even create extra heat, the safest move when you hear true grinding is to stop using the dryer until it is inspected.

A thumping or rumbling sound has a more forgiving range of causes. First, check the obvious: a balled-up comforter or a few heavy towels can thump as they tumble. If the load is fine and the thumping continues, worn drum support rollers are a frequent cause, especially if the dryer sat unused for a while and a roller developed a flat spot. A worn felt drum seal or a stretched belt can also let the drum sit slightly off balance and rumble.

There are a couple of quick things you can check yourself with the dryer unplugged. Open the door and rotate the drum by hand, listening for where the noise comes from and feeling for resistance. Remove any small objects like coins, bra wires, or screws that may have slipped past the drum seal and could be scraping. Clear lint from the area around the blower if you can reach it. These small checks sometimes reveal a simple cause.

Most noise repairs, though, mean opening the dryer cabinet and removing the belt to reach the rollers, bearing, idler pulley, or blower wheel. Diagnosing which worn part is responsible, and replacing it correctly, is technician work. It is also worth doing right, because a worn support part that gets ignored can eventually burn out the motor, which is a far costlier repair.
