Dryer Making Loud Thumping Noise While Running

A dryer should hum along quietly in the background, not sound like a drumline rehearsal. If your dryer is suddenly making loud thumping noises while running, it’s time to investigate. Ignoring the sound can lead to bigger (and more expensive) issues down the road.

In this article, we’ll walk through the common causes of dryer thumping, how to identify the noise, prevent future issues, and what to do when you need a repair.

What Are the Common Causes of Dryer Drum Making Thump Noise?

Several issues can cause a dryer to make a thumping noise, and most of them stem from worn-out or misaligned parts. Here are the most frequent culprits:

• Worn Drum Support Rollers: These rollers help the drum spin smoothly. When they wear out, they create a rhythmic thumping sound as the drum rotates.
• Flat Spots on Rollers: If your dryer hasn’t been used for a while, the rollers may develop flat spots, causing a temporary thump when you start the machine.
• Loose Baffles or Lifter Blades: These internal paddles help tumble clothes. If they’re loose, they can hit the drum and create noise.
• Objects Stuck in Drum Seals: Coins, buttons, or even screws can get lodged in the edges of the drum and thump against the walls during each cycle.
• Worn Drive Belt or Pulley: If the belt or pulley system is worn or damaged, it may cause irregular drum rotation and noise.

Each of these issues ranges from mildly annoying to potentially damaging if left unchecked.

How To Identify the Type, Duration, and Timing of Dryer Thump Noise?

To get to the root of the problem, pay attention to:

• When the noise happens: Is it constant or only during certain parts of the cycle?
• The type of noise: Is it a deep thump, a high-pitched squeal, or a banging sound?
• How long it lasts: Does it stop after a few minutes, or continue the entire cycle?

If the thumping stops after the first few minutes, flat spots on the drum rollers could be to blame. Continuous noise often indicates a more persistent issue, like worn parts or loose hardware. Listening carefully can help narrow down the problem before diving into repairs.

How To Prevent Thump Noises in Dryers?

Prevention is always better than repair. Here are some practical tips to keep your dryer running quietly:

• Avoid overloading the drum: Too many clothes can unbalance the drum and stress the rollers.
• Inspect pockets before washing: Remove coins, keys, and small items that could damage internal parts.
• Clean the lint filter regularly: A clogged lint trap can cause airflow issues and stress mechanical components.
• Schedule regular maintenance: A once-a-year inspection can catch wear-and-tear before it leads to noise or breakdowns.

Treat your dryer well, and it’ll reward you with years of quiet, efficient service.

How to Troubleshoot the Problem and Repair It?

If you’re handy, there are a few steps you can take to troubleshoot:

• Unplug the dryer and remove the access panel.
• Check the drum rollers for wear or flat spots. Spin them by hand — if they wobble or resist movement, they may need replacing.
• Inspect the drive belt for cracks, fraying, or slipping.
• Tighten any loose screws inside the drum or on the baffles.
• Look for debris in the drum seals or other moving parts.

If you’re unsure or don’t feel comfortable opening the dryer, it’s best to call a professional. DIY fixes can sometimes lead to more damage if done incorrectly.

Dryer Thumping by Brand: What to Expect

Not all dryers thump for the same reason — and knowing your brand’s common failure points can save you a lot of guesswork. Here’s a quick breakdown of what to look for based on the most popular dryer brands serviced by GIR Appliance in The Woodlands and surrounding Houston-area communities:

• Whirlpool / Maytag: Rear drum support rollers are the most frequent failure point on these models. As rollers wear down, the drum loses support and begins to wobble, producing a steady rhythmic thump with each rotation. Older Whirlpool and Maytag dryers are also prone to rear felt seal wear — once the seal deteriorates, the drum can rub directly against the back bulkhead and create a scraping thump that gets worse over time.
• Samsung: Samsung dryers are well-known for drum bearing ring failures. The bearing ring supports the front of the drum, and when it cracks or wears out, you’ll hear a loud thumping or grinding noise that intensifies as the drum spins faster. Front drum glides are another common culprit — these small plastic or nylon slides allow the drum to rotate smoothly against the front panel, and worn glides cause the drum to drag and thump.
• LG: LG dryers often experience both front drum bearing failures and drum support roller wear simultaneously, which can produce a combination of squealing and thumping. If your LG dryer is making a noise that shifts between a squeal and a thump depending on load size, both bearings and rollers should be inspected.
• GE: General Electric dryers most commonly develop thumping from worn drum rollers or a failing idler pulley. The idler pulley maintains tension on the drive belt, and when it wears out, the belt can skip or vibrate, creating an irregular thumping sound. GE dryers that are five or more years old are also prone to loose or cracked drum baffles that bang against the drum interior during each tumble cycle.
• Kenmore: Kenmore dryers are typically manufactured by either Whirlpool or Frigidaire depending on the model series, so the same components apply. Check the model number prefix to determine which platform your Kenmore is built on, then troubleshoot accordingly using the Whirlpool or Frigidaire component list.

When Thumping Means Something Serious

Most dryer thumps are nuisances that can be repaired without urgency — but some thumping patterns are warning signs of a more serious mechanical failure. Knowing when to stop the machine and call a technician right away can prevent a minor repair from turning into a full appliance replacement.

Thump turns into a grind (metal on metal): If the sound shifts from a rhythmic thump to a harsh grinding or scraping noise, the drum may be dragging directly against the drum housing or rear bulkhead. This usually means a drum bearing, felt seal, or drum glide has completely failed. Running the dryer in this condition can score the drum itself, turning a $150 bearing fix into a much more costly repair. Stop the dryer immediately and call for service.

Drum stops mid-cycle: If the drum suddenly stops spinning while the motor is still running, the dryer belt may have snapped. A snapped belt often produces one loud thump followed by silence from the drum. The motor will continue to hum, but clothes won’t tumble. Do not continue running the dryer — a broken belt can cause the motor to overheat.

Burning smell accompanies the thumping: A burning odor combined with a thumping noise is a red flag. This typically indicates that a belt or roller is overheating due to friction, or that lint has accumulated near a hot component. If you smell burning, unplug the dryer immediately. This situation warrants urgent attention — both for appliance safety and fire prevention. A technician should inspect the unit before it’s used again. If the problem turns out to be related to the rollers, our guide on identifying drum roller problems covers what a technician will check during the inspection.

Frequently Asked Questions

Why does my dryer thump only at the start and then stop?

This is almost always caused by flat spots on the drum support rollers. When a dryer sits unused for an extended period — even just a week or two — the rollers can develop a flat area on the side that rests against the drum shaft. When the drum starts spinning, that flat spot creates a periodic thump until the roller warms up and rounds out. If it happens consistently or gets worse over time, the rollers should be replaced before they fail completely.

Can a dryer thumping noise damage my clothes?

In most cases, a thumping dryer won’t damage your clothes directly. However, if the noise is caused by loose baffles or drum components, sharp edges can snag delicate fabrics. Foreign objects causing the thump — like coins, belt buckles, or loose screws — can also leave marks or holes in clothing. If you hear an irregular banging rather than a steady rhythmic thump, check the drum interior for loose hardware before running another load.

Is it safe to keep running a dryer that’s making thumping noises?

It depends on the cause. A mild thump from flat-spotted rollers at startup is generally low-risk for short-term use. But if the thumping is continuous, getting louder, or accompanied by grinding or a burning smell, you should stop using the dryer until it’s inspected. Running a dryer with a failing belt, seized roller, or dragging drum puts unnecessary stress on the motor and can create a fire hazard if overheating occurs near the lint trap or drum housing.

My dryer started thumping after sitting unused for a month — why?

This is the classic flat-roller scenario. Drum support rollers are made of rubber or plastic, and when the dryer sits idle, the rollers compress slightly under the weight of the drum. Over a few weeks, the compressed side develops a flat spot. When the drum spins again, that flat section thumps with each rotation. The noise often goes away after 5–10 minutes of running as the rollers warm up and regain their round shape. If it persists or returns every time the dryer starts, replacement is recommended.
