Rhythmic thumping
A repeating bump or thud that matches drum rotation, often worse at the start of the cycle.
Start here: Start with the load itself, then check whether the drum feels lumpy or stiff when turned by hand.

Dryer Making Noise When Spinning
Direct answer: If your dryer is making noise when spinning, the most common causes are something loose in the drum, the dryer sitting unevenly, or worn drum support parts that let the drum rub or thump as it turns.
Most likely: Start by identifying the sound: a steady scrape usually means rubbing, a rhythmic thump often means a flat-spotted roller or something stuck in the drum seam, and a squeal points more toward worn support parts.
Listen to the noise for one full rotation pattern before you take anything apart. A dryer that is noisy only while spinning usually gives you a pretty honest clue. Reality check: a dryer that suddenly got loud rarely fixes itself. Common wrong move: replacing the heating parts because the dryer is hot and noisy at the same time, when the real problem is usually in the drum support path.
Don’t start with: Do not start by ordering random dryer parts or running the dryer longer to see if it quiets down. That often turns a small wear problem into a scorched belt, damaged drum, or motor strain.

What the noise sounds like usually tells you where to look first
Squealing or chirping
A sharp rubbery or metal-on-metal sound that may get louder as the dryer warms up.
Start here: Start with an empty test run, then move to worn support parts like the dryer idler pulley or drum glides.
Scraping or rubbing
A steady metal scrape, drag, or rubbing sound while the drum turns.
Start here: Look for something caught at the drum edge first, then check for a sagging drum or worn front support surfaces.
Rumbling or growling
A deeper rolling noise that sounds rougher than normal and may shake the cabinet slightly.
Start here: Check leveling and drum movement first, then suspect worn dryer drum support rollers.
Most likely causes
1. Loose item, zipper, or small object caught in the drum seam
This is the fastest, most common cause when the dryer still runs normally but suddenly starts scraping, ticking, or thumping with certain loads.
Quick check: Run the dryer empty for a minute. If the noise disappears, inspect the load, pockets, zippers, bra hooks, and the drum baffles and seams.
2. Dryer not level or load tumbling unevenly
An uneven cabinet or one heavy item can make a healthy dryer sound rough, especially with shoes, towels, or bedding.
Quick check: Push gently on the top corners. If the cabinet rocks, level the feet and retest with a balanced medium load.
3. Worn dryer drum support rollers
A repeating thump or rumble that stays even with an empty drum often comes from a roller that has worn flat, seized, or started wobbling.
Quick check: With power disconnected, turn the drum by hand. If it feels rough, lumpy, or noisy through one spot each rotation, rollers move up the list fast.
4. Worn dryer idler pulley or dryer drum glides
A squeal, chirp, or scraping sound is often caused by a pulley bearing drying out or front drum supports wearing thin so the drum starts rubbing.
Quick check: Listen for whether the sound is high-pitched and constant rather than a slow thump. Check for black dust, metal shavings, or a drum that sags at the front.
Step-by-step fix
Step 1: Empty the dryer and separate load noise from machine noise
A lot of spin noise is not a failed part at all. Shoes, buckles, coins, and heavy wet items can sound exactly like a bad roller for one cycle.
- Unplug the dryer before putting your hands inside the drum.
- Remove the entire load and check pockets, zippers, drawstrings, bra hooks, and anything with metal hardware.
- Look along the drum seams and baffles for a coin, screw, button, or other small object stuck where the drum turns.
- Plug the dryer back in and run it empty on an air-only or no-heat setting for a short test.
- Listen for whether the noise is gone, still there, or changed from a thump to a scrape.
Next move: If the dryer is quiet when empty, the machine is probably fine. Reload with a smaller, balanced load and avoid hard items tumbling loose. If the same noise is still there with an empty drum, move on to cabinet stability and drum feel.
What to conclude: Noise that disappears when empty usually points to the load or a loose object. Noise that stays with an empty drum points to the dryer itself.
Stop if:
- You smell burning lint, hot rubber, or electrical odor.
- You hear harsh metal scraping that gets worse within seconds.
- The drum stops turning smoothly or the dryer struggles to start.
Step 2: Check leveling, feet, and simple cabinet vibration
A dryer that rocks on the floor can sound much worse than it is, and this is the easiest fix on the page.
- With the dryer off, press down on each top corner and feel for rocking.
- Adjust the dryer feet until the cabinet sits solidly without wobble.
- Make sure the dryer is not touching the wall, vent pipe, washer, or trim in a way that can transfer vibration.
- Retest with a medium mixed load, not one heavy blanket or a pair of shoes.
- Listen for whether the noise is now just normal tumbling instead of a hard thump or rumble.
Next move: If leveling and load balance calm the noise down, keep using the dryer and avoid single heavy items that slap the drum. If the noise is still there, especially with an empty drum, check how the drum feels by hand.
What to conclude: A cabinet vibration problem usually changes right away when the dryer is leveled. A true internal wear problem usually does not.
Step 3: Turn the drum by hand and feel for drag, flat spots, or rubbing
This is the cleanest way to separate a support problem from a simple vibration issue without buying parts first.
- Unplug the dryer again.
- Open the door and rotate the drum by hand several full turns.
- Feel for one rough spot each rotation, a dragging scrape, or a loose sagging front edge.
- Watch the drum gap at the front if visible and note whether it looks even or if one side dips.
- If your dryer has a light inside, look for rub marks, black dust, or shiny worn spots near the front drum edge.
Next move: If the drum turns smoothly and quietly by hand, the problem may be load-related or a vibration issue that only shows up under weight. If the drum feels rough, lumpy, or rubs in one area, internal support parts are the likely next move.
Step 4: Inspect the drum support path if the sound points inside
By this point, you have ruled out the easy stuff. Now you are looking for the wear parts that actually make this symptom happen.
- Disconnect power and open the dryer cabinet only as far as needed for safe access.
- Inspect the dryer drum support rollers for flat spots, wobble, seized bearings, or obvious wear.
- Inspect the dryer idler pulley for rough spinning, side play, or a dry squealing bearing.
- Inspect the front drum support area for worn dryer drum glides, missing glide material, or drum rub marks.
- Check the dryer belt for fraying or glazing, but treat it as a secondary clue unless it is clearly damaged.
- Vacuum out loose lint while you are in there so you can see fresh rub marks clearly.
Next move: If you find a worn roller, bad idler pulley, or worn glides, replace the failed support parts before using the dryer again. If the support parts look sound and the noise is still unexplained, stop before guessing. A motor or blower issue can mimic drum noise, but that is a different repair path.
Step 5: Replace the confirmed wear part, then verify with an empty run and a normal load
Once the failed support part is identified, the fix is usually straightforward. The important part is confirming the noise is actually gone before putting the dryer back into regular use.
- Replace only the dryer support part that matches the wear you found: dryer drum support roller, dryer idler pulley, or dryer drum glides.
- Reassemble the dryer fully and make sure the drum turns freely by hand before restoring power.
- Run the dryer empty for several minutes and listen for smooth rotation.
- Then run a normal balanced load and confirm there is no thump, squeal, or scrape.
- If the noise remains unchanged after replacing the clearly worn support part, stop and reassess for a blower wheel or motor issue rather than stacking more random parts.
A good result: If the dryer runs smoothly empty and loaded, the repair is complete.
If not: If the same noise is still present after a confirmed support-part repair, the problem is likely outside the drum support path and is worth a more targeted diagnosis.
What to conclude: A successful repair should change the sound immediately. If nothing changes, the original diagnosis was incomplete or the noise source is elsewhere in the dryer.

FAQ
Why is my dryer making a thumping noise when it spins?
Most of the time, a rhythmic thump comes from either the load itself or a worn dryer drum support roller. If the thump stays with an empty drum and repeats at the same point each rotation, a flat-spotted roller is a strong suspect.
Can I keep using a noisy dryer for a while?
If the noise is mild cabinet vibration from an uneven load, yes. If it is a new squeal, scrape, or heavy rumble, stop using it until you check it. Support-part noise tends to get worse, not better, and it can take the belt or drum with it.
What does a squealing dryer usually mean?
A squeal during drum rotation usually points to a worn dryer idler pulley or another dry support surface in the drum path. It is less often a heating problem. The sharper and more constant the squeal, the more likely you are dealing with a worn moving support part.
Why does my dryer only make noise with clothes in it?
That usually means the load is the trigger. Heavy wet items, shoes, metal hardware, or an unbalanced load can make a normal dryer sound bad. Run it empty for a short test. If the noise disappears, focus on the load before opening the machine.
Could low airflow cause a dryer to sound noisy while spinning?
Low airflow does not usually create a spin noise by itself, but overheating and lint buildup can make existing wear parts fail faster. If the dryer is noisy and also running hot or taking too long to dry, check the vent path too.
