Dryer Making Loud Noises? Squeaking, Thumping, and What They Mean

A dryer should hum along quietly. When it starts squeaking, thumping, or grinding, it's telling you that the parts carrying the drum are wearing out. Here's how to read the noise.

What Each Sound Usually Means

Squeaking or squealing. This is the classic worn-roller or worn-idler-pulley sound. The drum rides on small support rollers, and a tension pulley keeps the belt tight. When their bearings dry out, they scream. The noise often comes and goes at first, then becomes constant.

Rhythmic thumping. A thump once per drum revolution usually means a flat spot on a roller, a damaged drum seal, or something caught between the drum and the housing. If it thumps in time with the rotation, it's rotation-related — not the motor.

Grinding or scraping. Metal-on-metal grinding is more urgent. It can mean a failed roller that's let the drum drop and rub against the housing, or a broken drum glide. Running a dryer in this state can damage the drum itself, which turns a small repair into a big one.

Rattling. Check the easy stuff first: loose change, buttons, or a zipper caught in the drum baffles. If it's empty and still rattles, a blower wheel or baffle may have come loose.

When to Call a Technician

Dryer noises don't fix themselves — they get worse, and a failed roller can take out the belt, the pulley, or the drum. Call when:

• The squeaking or thumping is constant, not occasional
• You hear grinding or metal-on-metal contact
• The drum doesn't turn smoothly by hand (unplug it first and try)
• The dryer takes much longer to dry than it used to

These wear parts — belt, idler pulley, drum rollers — are exactly what our Dryer Preventive Maintenance Plan covers: we open the dryer up, deep-clean the interior cavity, and replace the worn parts before they fail. It's the cheapest insurance against a dead dryer and a fire risk from lint-packed internals.
