Grinding once per drum rotation
A scrape or grind repeats in a steady rhythm as the drum turns.
Start here: Start with the drum edge, front glides, rear support rollers, and anything stuck between the drum and housing.
Dryer noise troubleshooting
Dryer Making Grinding Noise
Direct answer: A dryer making a grinding noise usually has something rubbing in the drum path, a worn drum support part, a blower wheel issue, or a seized roller. Start by stopping use if the sound is harsh or sudden, then check for loose items, scrape marks, and whether the noise happens only while the drum turns.
Most likely: The most common cause is worn drum support rollers or a damaged drum glide or felt seal letting metal or plastic rub where it should not.
A true grinding sound is different from a light rattle or normal thump. It usually sounds like metal-on-metal, hard plastic scraping, or a rough dragging noise that gets worse as the dryer runs. Reality check: dryers rarely fix this noise on their own. Common wrong move: keep running it for a week to see if it settles down. That often turns a small wear part into a damaged drum, belt, or motor.
Don’t start with: Do not start by ordering a motor or control part. Grinding is usually a mechanical rub, not an electronic failure.
If the noise started suddenly after a loadCheck for coins, bra wires, zippers, or other hard items caught at the drum edge before opening the cabinet.
If the noise is there every time the drum turnsFocus on drum support rollers, drum glides, felt seals, and the blower area before suspecting the motor.

What the grinding noise sounds like
Constant grinding the whole time
The sound stays on continuously while the dryer is running, not just once per turn.
Start here: Check the blower wheel area and badly worn rollers first, especially if the sound comes from low in the cabinet.
Grinding with a burning smell or heat buildup
You hear grinding and also notice hot cabinet panels, a hot laundry room, or a scorched smell.
Start here: Stop using the dryer and check airflow and internal rubbing damage. If the smell is strong, move to /dryer-burning-smell.html.
Grinding only with heavy loads
The dryer is quieter empty but grinds with towels, jeans, or bedding.
Start here: Look for worn drum support rollers, flattened glides, or a sagging drum that only rubs under weight.
Most likely causes
1. Worn dryer drum support rollers
When rollers wear flat, seize, or wobble, the drum drags instead of rolling smoothly. The sound is usually rougher with heavier loads and often comes from the rear or lower cabinet.
Quick check: With power disconnected, turn the drum by hand. If it feels rough, hangs up, or sounds gritty, worn rollers are high on the list.
2. Damaged dryer drum glide or felt seal
If the front drum support wears through, the drum lip can scrape plastic, felt, or metal. You may see black dust, fabric marks, or shiny rub spots near the front opening.
Quick check: Open the door and inspect the front drum edge. Look for missing glide material, torn felt, or scrape marks around the opening.
3. Object stuck in the drum gap or blower housing
Coins, bra wires, screws, and zipper parts can make a sharp grinding or scraping sound and may start all at once after one load.
Quick check: Check the lint screen area, drum seams, and around the front and rear drum edges for anything hard catching as the drum turns.
4. Loose or damaged dryer blower wheel
A blower wheel that is rubbing its housing or wobbling on the motor shaft can make a steady grinding or growling sound from low in the dryer.
Quick check: If the sound seems strongest near the lint filter or lower front area and does not match drum rotation, suspect the blower area.
Step-by-step fix
Step 1: Stop the dryer and pin down the kind of noise
You want to separate a true grinding noise from a click, thump, or airflow whistle before taking anything apart.
- Run the dryer for just a few seconds, then stop it if the noise is harsh.
- Listen for whether the sound repeats once per drum turn or stays constant the whole time.
- Note where the sound seems strongest: front opening, rear panel, or low near the lint filter or blower area.
- If you also smell burning, feel unusual heat, or see lint dust blowing out, stop using the dryer.
Next move: If the sound turns out to be a light clicking or a loose item in a pocket, you may avoid deeper disassembly. If it is clearly a grinding or scraping noise, move on to the simple external checks before opening the cabinet.
What to conclude: Noise timing tells you a lot. Once-per-turn points to the drum path. Constant grinding points more toward the blower area or badly worn support parts.
Stop if:
- You smell burning rubber, hot metal, or scorched lint.
- The drum stops turning normally or the dryer struggles to start.
- You see sparks, smoke, or heavy lint discharge.
Step 2: Check for loose items and obvious drum rub
A trapped object is common, fast to confirm, and much cheaper than guessing at internal parts.
- Unplug the dryer or switch off power before putting hands near moving parts.
- Remove the lint screen and look down the chute for coins, screws, or other hard debris you can safely retrieve.
- Open the door and slowly rotate the drum by hand.
- Look and feel for scrape points at the front drum lip, torn felt, missing glide strips, or anything caught between the drum and front bulkhead.
- Check inside the drum for bra wires, zipper tabs, or metal pieces sticking through drum holes or seams.
Next move: If you remove an object and the drum now turns smoothly by hand, test the dryer with an empty load. If the drum still feels rough or you see wear at the drum support area, keep going.
What to conclude: A sudden new grinding noise after one load often comes from debris. Visible rub marks or torn support material point to worn drum glides or felt seals instead.
Step 3: Turn the drum by hand and judge the support parts
Hand-turning the drum with power off is the cleanest way to feel seized rollers, a sagging drum, or a rough support surface.
- With the dryer unplugged, rotate the drum several full turns by hand.
- Notice whether it turns smoothly, drags in one spot, or makes a gritty rumble.
- Lift up gently on the front of the drum through the door opening. Excessive play can mean worn front glides or felt support.
- If the drum sags or scrapes more when you lift or press on it, suspect worn drum glides, felt seals, or rear rollers.
- If the cabinet design allows safe access after removing panels, inspect the dryer drum support rollers for flat spots, wobble, or seized bearings.
Next move: If you confirm rough or seized rollers, or clearly worn front support material, you have a solid repair direction. If the drum feels fairly smooth but the running noise is still strong, shift attention to the blower area.
Step 4: Check the blower area if the noise is constant or low in the cabinet
A blower wheel can grind against its housing, collect debris, or loosen on the motor shaft, and that sound is often mistaken for bad rollers.
- Disconnect power before opening any access panel.
- Inspect the blower housing area for lint clumps, broken plastic, or debris contacting the wheel.
- Spin the blower wheel by hand if accessible. It should turn without scraping the housing.
- Look for a cracked hub, wobble, or signs the wheel has been rubbing one side of the housing.
- If the blower wheel is packed with lint and dust, clean it gently and recheck for free movement.
Next move: If cleaning or clearing debris stops the rubbing and the wheel spins true, reassemble and test the dryer empty first. If the wheel wobbles, scrapes, or feels loose on the shaft, the blower wheel is the likely fix. If the wheel is fine but the motor shaft feels rough, stop and consider a pro.
Step 5: Repair the confirmed wear point, then test with an empty cycle
Once you have a clear mechanical source, the right repair is usually straightforward. The key is replacing the worn support part, not just the loudest symptom.
- Replace the confirmed failed part: worn dryer drum support rollers, damaged dryer drum glide, torn dryer drum felt seal, or a loose damaged dryer blower wheel.
- If one roller is seized or badly worn, inspect the rest of the drum support path closely before reassembly so you do not leave a second worn part behind.
- Vacuum out loose lint while the dryer is open, but do not treat vent-cleaning tools as the fix for a grinding noise.
- Reassemble carefully, making sure the drum sits correctly on its supports and turns freely by hand before restoring power.
- Run the dryer empty for a few minutes, then with a small load, and listen for any remaining scrape or rumble.
A good result: If the dryer runs smoothly and the drum turns quietly under load, the repair is complete.
If not: If the noise remains after confirmed support parts and blower checks, stop before buying more parts blindly. The motor or a less obvious drum alignment problem may need in-person diagnosis.
What to conclude: A good repair should change the sound right away. If nothing changes, the original diagnosis was incomplete or there is more than one worn component inside.

FAQ
Can I keep using a dryer that is making a grinding noise?
Usually no. A grinding dryer is often rubbing through a support part or dragging on a seized roller. Keep running it and you can turn a small repair into a damaged drum, belt, blower wheel, or motor.
Is a grinding noise usually the motor?
Not usually. Most dryer grinding noises come from drum support rollers, front glides, felt seals, or something stuck in the drum path. The motor moves higher on the list only after those checks are ruled out or you confirm rough motor shaft play.
Why does my dryer grind only with heavy loads?
That usually points to worn support parts. A heavy load makes the drum sag more, so a weak roller, worn glide, or torn felt seal starts rubbing hard enough to hear.
What is the difference between grinding and squealing in a dryer?
Squealing is usually a high-pitched friction sound from a belt path or support part starting to dry out or wear. Grinding is rougher and harsher, more like scraping, dragging, or gritty rolling. Grinding deserves quicker attention.
Could something in the lint filter area cause a grinding noise?
Yes. Hard debris can fall into the lint chute or blower housing and rub the blower wheel. That often sounds like a steady grind from low in the cabinet rather than a once-per-turn scrape from the drum.
Do I need to replace all the dryer drum support rollers if only one is bad?
At minimum, replace the confirmed failed roller. But if one roller is seized or badly flat-spotted, inspect the others closely while the dryer is apart. On an older dryer, multiple support parts often wear together.
