Bang or thump only with bulky loads
The dryer sounds normal empty, but towels, jeans, bedding, or a single heavy item make it pound or hop.
Start here: Start with load balance and trapped items before suspecting internal parts.

Dryer Drum Banging Noise
Direct answer: A dryer drum banging noise is most often a heavy item thumping around, something trapped in the drum, or worn drum support parts letting the drum drop and hit as it turns.
Most likely: Start by running the dryer empty for a minute. If the banging disappears, the load is the issue. If it still bangs empty, look next for a loose dryer drum baffle, worn dryer drum rollers, or a damaged dryer drum support surface.
Listen to the sound before you take anything apart. A soft repeating thump with bulky laundry is different from a hard metal-on-metal bang that happens empty. Reality check: one pair of shoes or a wet towel can sound worse than a failing part. Common wrong move: replacing parts because the dryer is noisy without first running it empty.
Don’t start with: Do not start by ordering electrical parts or a control board. A banging sound is usually mechanical and usually visible once you separate empty-drum noise from load noise.
Bangs only with clothes inside?Redistribute the load and remove heavy single items like shoes, rugs, or one soaked towel.
Bangs even when empty?Stop using it until you check for a loose dryer drum baffle or worn dryer drum support parts.

What the banging sounds like
Hard bang even when the dryer is empty
You hear a repeating knock or bang once per drum turn with no clothes inside.
Start here: Check for a loose dryer drum baffle or worn dryer drum rollers first.
Metallic bang with scraping
The noise is sharper than a soft thump and may come with rubbing, scraping, or a drum that feels rough by hand.
Start here: Look for a dropped drum, damaged front glide area, or a drum seam or baffle problem.
New dryer or long-idle dryer thumps at startup
The drum makes a rhythmic thump for the first few minutes, then improves as it warms up.
Start here: A roller flat spot is possible, but confirm it by running empty and listening for a once-per-turn thump.
Most likely causes
1. Unbalanced or heavy laundry load
This is the most common cause when the noise shows up only with clothes. One heavy item can slap the drum and cabinet hard enough to sound like a broken part.
Quick check: Run the dryer empty. If the banging stops, reload with mixed items and avoid single heavy pieces.
2. Loose dryer drum baffle
A baffle that has loosened inside the drum can bang once each revolution and may get louder with clothes tumbling over it.
Quick check: Reach inside the cool drum and push on each baffle. Any movement, rattle, or lifted edge is a strong clue.
3. Worn dryer drum rollers
When rollers wear, seize, or develop flat spots, the drum can drop and thump as it turns, especially empty or at startup.
Quick check: Turn the drum by hand with power disconnected. Rough spots, resistance, or a repeating bump point toward roller trouble.
4. Worn dryer drum glides or support surface
On some dryers the front of the drum rides on glides or a support strip instead of rollers. When those wear through, the drum can knock, scrape, or sit low.
Quick check: Look for black dust, scraping marks near the front opening, or a drum lip that sags more than usual.
Step-by-step fix
Step 1: Run it empty and separate load noise from machine noise
You want to know whether the drum is actually banging on its supports or whether the laundry itself is causing the noise. That one check saves a lot of unnecessary teardown.
- Unplug the dryer first, then make sure the drum is empty and the lint screen is in place.
- Spin the drum by hand and listen for a bump, scrape, or loose piece inside.
- Plug it back in and run it empty on an air-only or low-heat setting for about a minute.
- Listen for whether the bang happens once per drum turn or only when the drum is loaded later.
- If the dryer is gas, do not open gas components for this noise check; you are only listening and observing.
Next move: If the dryer is quiet empty, the machine itself is probably fine and the banging is load-related. If it still bangs empty, move on to drum hardware and support checks.
What to conclude: Noise that disappears empty usually points to load balance, trapped items, or bulky laundry. Noise that stays empty is much more likely to be a loose internal drum part or worn support hardware.
Stop if:
- You smell burning, hot rubber, or scorched lint.
- The drum binds, stops, or is hard to turn by hand.
- The dryer cabinet shakes violently or walks across the floor.
Step 2: Check for simple inside-the-drum causes
A loose baffle or a hard object caught in the drum can sound almost identical to a bad support part, and you can often confirm it without opening the cabinet.
- With the dryer unplugged and cool, inspect the drum interior with a flashlight.
- Press on each dryer drum baffle from end to end. It should feel solid, not loose or clicky.
- Look for coins, screws, bra hardware, zipper pulls, or other hard items stuck at the drum seam or near the front lip.
- Check the lint screen housing area for anything that may have fallen where the drum passes close by.
- If the noise started right after washing shoes, pet bedding, or a rug, remove those items and test again with a normal mixed load.
Next move: If you find a trapped object or a loose baffle and the noise stops after correcting it, you are done. If the drum interior looks solid and the bang remains, the support parts underneath or at the front are the next suspects.
What to conclude: A once-per-turn bang with a loose baffle is a strong match. If the inside hardware is solid, the drum is probably dropping or hitting as it rides on worn supports.
Step 3: Check the drum support feel by hand
Before you disassemble anything, the drum will usually tell you whether the supports are worn. Excess play, rough rotation, or a repeating bump narrows it down fast.
- Unplug the dryer.
- Open the door and lift up gently on the front edge of the dryer drum. Compare that movement to a light push downward.
- Rotate the drum slowly by hand several full turns.
- Feel for a flat spot, rough patch, or a point where the drum seems to drop and recover.
- Look at the front drum lip and opening for rub marks, black wear dust, or felt or glide material coming apart.
Next move: If the drum has obvious play, roughness, or a repeating bump, you have enough evidence to inspect the support parts inside. If the drum feels smooth and tight by hand but still bangs during operation, recheck for a loose baffle and watch for cabinet vibration or leveling issues.
Step 4: Inspect the dryer drum support parts
This is the point where the main mechanical causes become visible. You are looking for worn rollers, damaged glides, or a drum that has been riding low and hitting where it should not.
- Unplug the dryer and open the cabinet only as far as needed to access the drum support area.
- Inspect the dryer drum rollers if your dryer uses them. Look for flat spots, wobble, seized bearings, or heavy wear.
- Inspect the front drum support area if your dryer uses glides or slides. Look for missing glide material, worn-through plastic or felt, or metal-to-metal contact marks.
- Check the dryer drum baffle fasteners from the back side if accessible and look for looseness around the mounting points.
- Inspect the drum itself for a bent rim, cracked weld, or damage around the baffle mounts.
Next move: If you find worn rollers, worn glides, or a loose baffle mount, replace the failed part before running the dryer again. If the supports look good and the drum is not damaged, the noise may be coming from another moving part and a more specific noise page is the better next step.
Step 5: Replace the confirmed failed part or stop and call for service
Once the bad part is identified, the fix is usually straightforward. If the drum itself or cabinet structure is damaged, this stops being a simple parts swap.
- Replace worn dryer drum rollers if they are flat-spotted, seized, or loose on their shafts.
- Replace worn dryer drum glides if the front support surface is worn through or the drum has been scraping.
- Tighten or replace the dryer drum baffle only if the baffle or its mounting has clearly loosened or cracked.
- Reassemble the dryer fully, then run it empty first and listen before drying a normal mixed load.
- If the drum is bent, the frame is damaged, or the noise source is still unclear after inspection, book an appliance service call instead of guessing at more parts.
A good result: A successful repair leaves the dryer smooth and steady with no once-per-turn bang empty or loaded normally.
If not: If the bang remains after replacing the clearly worn support part, stop and have the dryer inspected for drum damage or another internal mechanical problem.
What to conclude: A clean repair confirms the diagnosis. If the noise survives a confirmed support-part repair, the remaining suspects are usually a damaged drum, another mechanical component, or a misdiagnosed noise type.

FAQ
Why does my dryer make a banging noise only with towels or bedding?
That usually points to load balance, not a failed part. Bulky items can roll into one heavy mass and hit the drum and cabinet hard. Test the dryer empty first. If it is quiet empty, change how the load is arranged before opening the machine.
Can worn dryer drum rollers cause a loud bang?
Yes. Flat-spotted or seized dryer drum rollers can make a repeating thump or bang once each revolution, especially when the dryer first starts or even when it is empty.
How do I know if the dryer drum baffle is loose?
With the dryer unplugged and cool, press on each baffle inside the drum. It should feel solid. If one clicks, shifts, or lifts at an edge, it can bang as the drum turns.
Is it safe to keep using a dryer that bangs?
Not if the noise is strong, happens empty, or comes with scraping or a burning smell. Continued use can wear through support parts, damage the drum, or create lint and heat problems inside the cabinet.
Could an unlevel dryer cause banging?
It can add cabinet shake and make load thumps worse, but a true once-per-turn bang usually comes from the load, a loose baffle, or worn drum support parts. Leveling is worth checking, but it is not the first suspect when the noise repeats every revolution.
What if the dryer bangs and also smells hot?
Stop using it and inspect further or call for service. A banging dryer with a hot or burning smell can mean the drum is rubbing where it should not, which can create heat, wear dust, and lint buildup in the wrong places.
