The short version: a dryer has only a handful of moving parts — a motor, a belt, an idler pulley, two or four drum rollers or a rear bearing, front drum glides, and a blower wheel — and each one makes its own noise when it wears. A squeal is a bearing, a roller or the idler pulley. A thump is a roller with a flat spot. A scrape is a glide or something caught between the drum and the cabinet. A rattle is debris in the blower. A hum with no turning is a belt or a jam. A loud noise from a dryer is almost always inexpensive to fix, and a good repair replaces the whole set of wear parts at once so you are not back in six months. Here is how I sort dryer noise on my Tampa Bay calls.
Match the sound to the part
When a dryer is making loud noises, the kind of noise names the part — a rattling noise, a grinding noise and a squeal come from three different places. Stand next to the dryer with a load in it, then with the drum empty. Note whether the noise follows the drum (stops the instant you open the door and the drum coasts to a halt) or continues while the motor runs down (blower or motor). That one observation splits the machine in half.
| The sound | When you hear it | Most likely part |
|---|---|---|
| Squeal or screech, steady, follows the drum | Whole cycle, worse cold | Rear drum bearing (GE, Frigidaire), drum rollers, idler pulley |
| Thump or bump, once per drum turn | Worst at start, may smooth out | Drum support roller with a flat spot; worn roller shaft |
| Scrape or grind, metallic | Whole cycle; marks on clothes | Drum glides / front felt seal worn through; foreign object between drum and bulkhead |
| Rattle or buzz, light | Whole cycle | Coins, screws or a bra wire in the blower housing; loose blower wheel; loose panel |
| Loud roar or rumble that rises with speed | Whole cycle | Blower wheel loose on the shaft; rear bearing worn through |
| Hum, drum does not turn | At start | Broken belt (drum spins freely by hand) or a jammed blower / seized bearing (drum stiff by hand) |
| Clicking for a few seconds at start | Start only, gas dryer | Normal — igniter and gas valve |
| Whistle, flap or whoosh from behind | Whole cycle | Vent, outside damper, or a crushed flex duct — not the dryer |
Free checks before you call anyone
- Empty the drum and check the baffles. Run a hand around the inside of the dryer drum, and look in the seam at the front and rear where coins and underwires slip through. Pull the lint trap and shine a light down the housing — that is where the coin that rattles usually lives.
- Turn the drum by hand, dryer unplugged. It should turn smoothly with a little resistance from the belt. Free-spinning with no resistance: the belt is broken. Stiff, gritty or catching: a roller, a glide or the rear bearing is worn, or something is caught behind the drum.
- Level the dryer. A dryer with one foot off the floor rocks on every drum revolution and the cabinet drums like a speaker box. A level on top, feet adjusted, and a "loud dryer" often goes quiet.
- Look behind it. A crushed foil flex duct whistles; a vent that has come off the dryer flaps against the wall; a jammed outside damper roars. None of those are dryer repairs.
- Listen at start with the door open. On a gas dryer, a few clicks and then a whoosh is the igniter. Normal. Clicking that never stops is not.
Squeal or screech: drum bearing, rear drum support and the idler pulley
A steady squeal that follows the drum comes from one of three places, and which one depends on how your dryer supports its drum.
Rear drum bearing. GE, Frigidaire, Electrolux and many older Kenmore and Maytag dryers hang the back of the drum on a single ball-and-socket or sleeve bearing at the center of the rear bulkhead. When the plastic or nylon wears, the drum drops slightly, rides on metal, and squeals — then grinds, then roars as it wears through. The tell: the noise changes pitch when you press up on the drum from inside. The bearing is a small kit; the drum has to come out to fit it.
Drum rollers. Whirlpool, Maytag, Kenmore, Samsung, LG and newer Frigidaire dryers instead rest the drum on two or four rubber-tired rollers. When a roller's shaft dries out or the tire hardens, it squeals; when the tire develops a flat spot, it thumps (next section). Rollers are always replaced as a set — a new roller next to a worn one squeals again within months.
Idler pulley. The spring-loaded pulley that keeps the belt tight rides on a small plastic wheel or a bearing. When it dries out it makes a high squeal that is often loudest at start-up and quiets as it warms. On Samsung and many Whirlpool-built dryers the idler pulley is one of the most common squeal sources there is. It is an inexpensive part and I replace it with the rollers and belt as one kit, because they wear on the same schedule.
Thump: drum rollers and the flat spot
A rhythmic thump — once per drum revolution, like a tennis shoe going around — is the signature of a drum support roller with a flat spot. The rubber tire sits under the weight of the drum in the same position for weeks, takes a set, and then bumps over that flat every turn. It often smooths out after ten minutes of running; if it does not, the roller shaft has worn a groove and the roller wobbles. A dryer that sits unused for a season, which happens in a lot of seasonal homes from St. Petersburg to New Port Richey, comes back to life thumping for exactly this reason. A worn roller also lets the drum sag, which is how a thump turns into a scrape.
The drive belt can thump too: a belt that has been sitting with a kink, or one with a split rib, slaps the drum once a turn. A belt is the cheapest part in the machine and comes out with the same disassembly as the rollers.
Scrape and grind: glides, the felt seal, foreign objects and the blower wheel
A metallic scrape means metal is touching metal somewhere it should not. The usual place is the front of the drum. The drum's front lip rides on plastic or nylon drum glides (Whirlpool, Maytag, LG) or a felt drum seal (GE, Frigidaire, Samsung) mounted on the front bulkhead. When they wear through, the drum edge scrapes the bulkhead, and you find gray or black marks on clothes and a fine metallic dust in the lint trap. Glides and seals are cheap; the labor is getting the drum out, which is why they go in together with the rollers.
A foreign object — a screw from a pocket, a bra wire, a hair clip — slips through the gap at the front or rear seal and lodges between the drum and the cabinet. The scrape is loud, sudden and often intermittent, and it stops when the object shifts. Fishing it out means the front panel off. A blower wheel that has cracked at its hub or picked up lint and a coin grinds against its housing; you hear that one after the drum stops, while the motor coasts.
Rattle and buzz: blower housing debris, coins and loose panels
A light rattle that continues for a moment after you open the door is almost always in the blower housing: coins, screws, buttons and lint balls that made it past the lint filter and sit against the wheel. On most dryers the blower is reached from the front, behind the lower panel; on GE it is at the back. A buzz that changes when you press on the cabinet is a loose panel, top or rear duct, and a buzz that starts with heat on an electric dryer can be the heating element coil sagging against its housing — that one belongs on the dryer not heating page, because it is a heater problem wearing a noise costume.
Hums but does not turn; clicks at start
A dryer that hums and does not turn is telling you the motor has power and cannot move. Open the door and turn the drum by hand. Spins freely: the belt is broken, the motor is fine, and the dryer's belt switch (on models that have one) is why it will not run. Stiff or seized: the blower wheel is jammed with lint or a foreign object, or the rear bearing has locked. Do not keep hitting start — a motor that hums against a jam heats up, and a dryer motor with cooked windings is the expensive end of this page.
Clicking at the start of a cycle on a gas dryer is normal: the igniter glows, the gas valve coils click open, the burner lights with a soft whoosh. That should happen within a few seconds of the drum starting. Clicking that repeats every few seconds all cycle long, or clicking on an electric dryer, is a loose drum baffle, a coin in a drum seam, or a broken glide — mechanical, not gas.
Vent-side noises: the roar, the whistle and the flap
Not every noise behind the dryer is the dryer. A crushed or kinked flex duct whistles as air squeezes through. A vent that has separated from the dryer's exhaust flaps against the wall. An outside damper that has rusted or filled with lint slams or roars. A vent packed with lint makes the dryer work harder, run hotter and longer, and wear its rollers and bearings faster — so it is a noise cause twice over. If your dryer has become louder and slower to dry, clean the vent before assuming a part. A clogged vent is also the first thing to rule out on a dryer that will not heat.
Where the parts sit: Whirlpool and Maytag, GE, LG, Samsung
Whirlpool, Maytag, Kenmore, Amana and Roper (mostly built on the same platforms): the classic 29-inch dryer has two rear rollers, two front glides on the bulkhead, an idler pulley and a belt, all reached by lifting the top and removing the front panel. The newer 27-inch machines use four rollers. A roller-glide-pulley-belt kit is a stocked repair. GE dryers use a rear ball-and-socket bearing and front drum slides; the drum comes out the front. A squeal on a GE is nearly always that rear bearing. Frigidaire and Electrolux use a rear bearing kit and front glides as well, with the blower at the back on many models. LG dryers rest on two rear rollers with front glides and a notoriously vocal idler pulley. Samsung dryers use four rollers and an idler pulley that squeals when the bearing dries; a squeak on a Samsung under a few years old is very often that pulley. Brand pages: Whirlpool, Maytag, GE, LG, Samsung.
Repair or replace: the noisy-dryer math
Dryers are simple machines, and noise repairs are the cheap end of the appliance repair world: rollers, glides, an idler pulley, a felt seal and a belt are inexpensive parts, and one visit replaces the set. On almost any dryer that heats and turns, a noise repair is worth it, including dryers well past ten years — a fifteen-year-old Whirlpool with new rollers and a clean vent is a good dryer. The exceptions: a motor with failed bearings on a dryer past twelve years, where the motor plus the labor approaches a new machine; and a drum that has worn through at the front lip or cracked at a weld, which is a replace-the-dryer finding. The $69 diagnostic is applied 100% to the repair you approve, with a 90-day labor warranty. For the wider decision, including what a dryer's age really means, read dryer repair or replace.
How common is this? Search demand, measured
Ubersuggest counts about 390 U.S. searches a month for "dryer making noise," with peaks in September and January and a quiet stretch from April through July. The two peaks match the two times dryers go from light duty to heavy duty — back-to-school laundry and post-holiday bedding — which is exactly when a flat-spotted roller or a dry idler pulley starts announcing itself.
Search data: Ubersuggest, national monthly volume, last 12 months. September and January are when dryers go back to work after light duty — and when a roller that took a set over the quiet months starts thumping.
Expert opinion — Anatoli Didenco, owner, Perfect Appliance Repair Tampa. Open the door mid-cycle and listen to what happens. If the noise stops the instant the drum stops, it is the drum's support — rollers, glides, rear bearing, idler — and that is a cheap, worthwhile repair on a dryer of almost any age. If the noise keeps going while the motor winds down, it is the blower or the motor, and I want to see it before it cooks the windings. Whatever I find, the rollers, pulley and belt go in as a set; replacing one worn part next to three tired ones is how you pay for the same job twice.

Dryer making noise — quick answers
Is it safe to use a noisy dryer?
A squeak or a thump for a few more loads, yes. A grinding or scraping noise, a burning smell, or a hum with the drum not turning — stop. Grinding means metal is wearing on metal, and a dryer that hums without turning is a motor heating up under a load it cannot move.
What does a bad dryer bearing sound like?
A steady squeal or screech that follows the drum, sometimes changing to a grind as the bearing wears through; troubleshoot a loud noise by where it comes from, not by how loud it is. On Whirlpool and Maytag dryers the same squeal usually comes from the rear drum rollers or the idler pulley; on GE and Frigidaire it is the rear ball-and-socket bearing. Stopping the drum by hand ends the noise instantly in either case.
Why does my dryer sound like it has shoes in it?
A rhythmic thump once per drum revolution is a flat spot on a drum support roller — common after a dryer sits unused for weeks. If the thump smooths out after several minutes, the roller is flat-spotted but alive; if it does not, the roller or its shaft is worn and needs replacing.
Why does my dryer sound like a train or a jet engine?
A loud roar or rumble that rises with the drum is usually a rear drum bearing worn through or a blower wheel that has come loose on the motor shaft and is hitting its housing. Check the blower first: with the dryer unplugged, a loose wheel rattles when you reach in behind the lint filter and push on it.
Why does my dryer click when it starts?
On a gas dryer, a series of clicks for a few seconds after the drum starts is the igniter and gas valve doing their job — normal. A click that repeats every few seconds through the whole cycle, or a click on an electric dryer, is something else: a coin in the drum, a loose drum baffle, or a broken drum glide.
Can a clogged vent make a dryer noisy?
Yes, in two ways. Lint packed in the blower housing lets the blower wheel rub and buzz, and a dryer working against a blocked vent runs hotter and longer, which speeds up wear on rollers and bearings. A whistling or flapping noise from behind the dryer is usually the vent or its outside damper, not the machine.
Is a noisy dryer worth fixing?
Almost always. Rollers, glides, an idler pulley, a felt seal and a belt are inexpensive parts, and one visit typically replaces the whole set. The exception is a motor with failed bearings on a dryer past twelve years, where the motor plus labor approaches the price of a new dryer.
