A loud dryer isn’t just annoying. It’s usually a sign that something inside needs your attention before it turns into a bigger problem. Most dryer noises come from worn mechanical parts that rub, squeak, or rattle as the drum spins. The good news is that you can often identify the culprit by the type of sound you’re hearing.
Let’s break down the most common causes of dryer noise and what you can do to fix them. Some repairs are simple DIY projects, while others might need a professional hand.
Worn Drum Rollers
Drum rollers support the dryer drum as it spins. When they wear out, you’ll hear a loud rumbling or thumping sound. Most dryers have two or more rollers on the back of the drum, and some models also have front rollers.
To check if your rollers are the problem, open the dryer and manually spin the drum. If it doesn’t rotate smoothly or you feel resistance, the rollers are likely worn. You can also remove the front or back panel to visually inspect them for flat spots or damage.
Replace all the drum rollers at once, even if only one looks bad. They wear at similar rates, and replacing just one means you’ll be back to the same problem in a few months.

Universal kits work with most major brands and include multiple rollers for complete replacement
Damaged Drum Glides or Slides
These are plastic or felt pads that support the front of the drum. When they wear down, you’ll hear a scraping or grinding noise as metal rubs against metal. This problem is especially common in front-loading dryers.
Inspect the glides by looking at the front rim of the drum where it contacts the bulkhead. If you see worn spots or missing chunks, it’s time for new glides. This is a relatively easy fix that can save you from more expensive drum damage down the road.
You’ll find replacement dryer drum glides specific to your model number. Make sure to clean any debris from the drum rim before installing new ones.
Faulty Idler Pulley
The idler pulley maintains tension on the drive belt. When it starts to fail, you’ll hear a squealing or squeaking noise that gets louder as the dryer runs. Sometimes the bearing inside the pulley wears out, causing a grinding sound.
You can locate the idler pulley by removing the front or lower panel of your dryer. It’s usually a small wheel attached to a spring-loaded arm. Try spinning it by hand. If it doesn’t rotate freely or makes noise, replace it.

Loose Blower Wheel
The blower wheel pulls air through the dryer and pushes it out the vent. If it comes loose or gets clogged with lint, you’ll hear a rattling or clattering sound. This often happens when the set screw that holds the wheel in place works itself loose.
Access the blower wheel by removing the front panel and disconnecting the heating element housing. Check if the wheel is tight on its shaft and look for any objects or lint buildup. Tighten the set screw with an Allen wrench if it’s loose.
While you’re in there, take a look at the drive belt too. A worn or frayed dryer belt can also cause squealing or thumping noises and should be replaced before it breaks completely.
When to Call a Professional
Most dryer noise issues can be fixed with basic tools and replacement parts. But if you’re not comfortable taking apart your dryer, or if the noise persists after replacing obvious worn parts, call an appliance repair technician.
Also consider professional help if your dryer is still under warranty. DIY repairs might void the coverage. And if your dryer is more than 10 years old with multiple failing components, it might make more sense to replace the entire unit.
Frequently Asked Questions
How much does it cost to fix a noisy dryer?
Parts typically range from affordable for small components like rollers and glides to more for complete kits. Labor costs vary by region, but expect to pay between competitively priced and competitively priced for a service call if you hire a technician. Many homeowners can handle these repairs themselves with basic tools and save the labor cost.
Can I keep using my dryer if it’s making noise?
You can usually run a noisy dryer for a short time, but don’t ignore the problem. Worn parts put extra stress on other components and can cause more extensive damage. A failing roller or glide can damage the drum itself, turning a simple repair into a much more expensive one. Address unusual noises as soon as you notice them.
