Why is my dryer squealing?
Updated August 2026
A dryer that squeals or grinds as the drum turns is almost always worn drum support rollers or glide bearings, the small wheels and pads the drum rides on that dry out and flatten over years of use. They are cheap wear parts, usually $20–50 for a roller set, and a common DIY kit. A grind that gets louder means a roller or pulley is close to seizing, so fix it before it strands you mid-load. The ranked causes below help you place the noise.
Safety first: unplug an electric dryer (or shut off the gas on a gas model) before you open the cabinet to inspect rollers, the belt, or the idler, since the drum sits inches from live wiring and the belt path. A roller or pulley that is allowed to seize can also generate friction heat against packed lint, so a grinding dryer left to fail is one more reason to keep the lint screen and vent clean while you sort out the noise.
Causes, most likely first
| Cause | How likely | The fix | Typical cost |
|---|---|---|---|
| Worn drum support rollers | Most common | A rumble or squeal that rises with the tumble points at flat-spotted rollers. Replace the roller set and their shafts. | $20–50 part |
| Worn front drum glides or bearing | Common | Scraping from the front of the drum means the felt glides or front bearing have worn through. Replace the glide kit. | $10–30 part |
| Failing idler pulley | Common | A high-pitched squeal from a spring-loaded pulley riding the belt. Replace the idler pulley. | $10–40 part |
| Worn or cracked drive belt | Occasional | A thumping squeal from a glazed or fraying belt. Replace the belt before it snaps. | $10–40 part |
| Bad blower-wheel bearing or object in the blower | Occasional | A grinding or rattling near the blower means a cracked wheel or debris. Clear it or replace the wheel. | $20–80 part |
Check these first
- Note when the noise happens: a squeal at startup that fades points at the belt or idler, while a rumble throughout the tumble points at the rollers.
- With the dryer off and unplugged, open the door and spin the drum by hand, feeling for a rough or notchy spot.
- Listen to where the sound comes from: front-of-drum scraping is the glides, back-and-bottom rumble is the rollers or blower.
- Check the belt path if you are comfortable opening the top, looking for a glazed or fraying belt.
- Empty the drum and run it briefly: a noise that changes with load weight helps confirm rollers versus a fixed part.
Prevent it next time
Rollers, glides, idlers, and belts are wear parts, so many owners simply replace them as a kit when the first squeal shows up rather than chasing one part at a time. Keeping the lint screen and vent clean does not stop the wear, but it keeps friction heat from adding to it and is worth doing on the same visit. Our dryer maintenance checklist and dryer lifespan guide help you judge whether a noisy 12-year-old machine is worth the parts.
When to call a pro
Call a technician if you are not comfortable pulling the cabinet apart, if the dryer is gas, or if the noise is a hard grinding that suggests a seized bearing about to fail. The parts are cheap at $20–80, but professional labor to reach them brings the total to roughly $150–300. Since most dryers last 10–13 years, a $250 noise repair on a machine near that mark is where our when-to-replace-a-dryer guide and the cost calculator help you decide.

Is it safe to keep running a squealing dryer?
For a load or two while you order parts, usually yes, but not indefinitely. A squeal from worn rollers or an idler will keep worsening until the part seizes, and a seized roller or pulley can stop the drum, snap the belt, or generate friction heat next to lint. If the noise is a hard grinding rather than a light squeal, stop sooner, because that points at a bearing close to failure. Unplug the dryer and inspect it before it strands a wet load.
How much does it cost to fix a squealing dryer?
The parts are inexpensive: a roller set is $20–50, glides are $10–30, an idler pulley is $10–40, and a belt is $10–40. If you do the work yourself, a full roller-belt-idler kit often runs under $60. Paying a technician brings the total to about $150–300 once labor to open the cabinet is included. Because most dryers last 10–13 years, a DIY parts kit is an easy call on a newer machine, while a $250 pro repair on a decade-old dryer is closer to a toss-up.
How do I tell if it is the rollers, the idler, or the belt?
Listen to the timing and location. A squeal at startup that eases as the dryer warms up usually points at the idler pulley or a glazed belt. A steady rumble or thumping that runs through the whole tumble, and gets louder with a heavier load, points at flat-spotted drum rollers. A scraping from the front of the drum is the felt glides. With the dryer unplugged, spinning the drum by hand and feeling for a rough spot helps confirm rollers before you open anything.
Is a grinding dryer worth repairing or should I replace it?
It depends on age and what else is failing. Rollers, glides, idlers, and belts are cheap, so on a dryer under about 8 years old the repair is clearly worth it, often under $60 in DIY parts. Once a machine is past a decade, has a weak heating system, or needs a motor on top of the noisy parts, replacement starts to win. Since dryers average 10–13 years, our lifespan guide and the cost calculator are the fastest way to run that math.
