Dryer Making Loud Noise
Dryers are simple machines mechanically — a motor, a belt, and a drum riding on rollers — which is why a new noise almost always means one of those wear parts is failing. Squeaks, squeals, grinding, and thumping each have typical causes, and because the parts are inexpensive compared to the damage a seized roller or shredded belt can do, noisy dryers are best repaired early.
Common Symptoms
- • High-pitched squeal or squeak while tumbling
- • Rhythmic thumping in time with drum rotation
- • Grinding or scraping from inside the cabinet
- • Rattling or ticking from the blower area
- • Noise present even with an empty drum

Common Causes
Match the sound to the part: a rhythmic thumping usually means a drum roller has flat-spotted or the belt has a damaged section; a constant squeal points to the idler pulley or drum glides; grinding suggests a roller bearing or motor bearing running dry; and a ticking or scraping tied to airflow usually means something — a coin, a button — is caught in the blower wheel.
What Different Dryer Noises Mean
The drum rests on small support rollers that turn thousands of times per cycle. When their bearings wear, rollers develop flat spots and produce a rhythmic thumping; when they seize entirely, the drum drags and grinds. Rollers are normally replaced as a set, since the rest are as worn as the one that failed.
The idler pulley keeps tension on the drive belt and is the most common source of squealing. As its bearing dries out, it emits a high-pitched squeal that often changes with drum speed. A worn belt adds its own slapping or thumping as damaged sections pass over the pulley.
Noises tied to airflow rather than tumbling come from the blower. Small items pass the lint filter and land in the blower wheel, where they tick or rattle loudly. A loose blower wheel can also scrape its housing, producing a grinding noise that is easy to mistake for a motor failure.

Frequently Asked Questions
Why is my dryer squeaking so loudly?
The usual sources are a worn idler pulley, dry drum rollers, or worn drum glides. All are inexpensive wear parts, but reaching them requires opening the dryer cabinet.
What causes a thumping noise while the drum turns?
A drum roller with a flat spot or a damaged section of the drive belt passing over the pulley. A load of heavy items can cause a similar sound, so test with an empty drum first.
Why does my dryer make a grinding noise?
Grinding usually means a roller or motor bearing has worn dry, or the blower wheel is scraping its housing. Continuing to run the dryer can turn an inexpensive repair into a major one.
Is it safe to use a noisy dryer?
Briefly, but not long-term. Worn parts overheat from friction, belts snap, and seized rollers can scorch. Early repair is cheaper and avoids the dryer failing mid-load.
