Four Reasons Your Dryer Is Making Noise

October 1, 2019 Published by Leave your thoughts

“A few hard knocks ought to fix it” was one piece of free advice. “Did you try unplugging it and plugging it back in?” was another helpful tidbit. If we’re being honest, we’d all admit to trying these old tricks as a last resort for fixing something. And, every once in a while, these tricks may even appear to work, at least temporarily, which means we’re more likely keep trying them. If your dryer is making noise, however, chances are it’s in need of more than a few knocks or a “reset.” Here are four reasons your dryer is making noises in St. Peters, MO.


If you hear a thumping noise when running your dryer, the drive belt may be the cause. The drive belt wraps around the dryer drum, tension pulley and the drive motor, and it’s responsible for turning the dryer drum. Over time, the drive belt can become frayed, brittle and inflexible, which causes a thumping noise as the dryer drum turns. To determine if the drive belt is the culprit of the thumping noise, check the belt for signs of wear and fraying.

Squealing and thumping

Worn-out drum rollers often result in a thumping noise combined with a squealing noise. Most dryers have at least two drum support rollers on the back of the drum, while others have four rollers (two in the back and two in the front). You can easily check if your drum rollers are worn out by removing them from the shaft. Be sure to check the rollers themselves and the shafts for signs of wear.

Loud roar and thumping

When your blower wheel is loose, blocked or worn, the result can be a loud roar combined with a thumping noise. The blower wheel is responsible for guiding air through your dryer, from the heating chamber through to the exhaust vent. In most machines, the blower wheel is typically found attached to the motor shaft. An object or lint can get stuck in the blower wheel, or the blower wheel may wobble on the motor shaft. To check the blower wheel, you will need to check for signs of wear at the hub of the wheel, at the junction of the shaft.

Squealing and squeaking

If your dryer is making a squealing or squeaking sound, chances are you’ll need a new bearing. There are two types of bearings: a shaft attached to a sleeve bushing, or a ball-and-socket type at the back of the drum. To check the drum bearing, you will need to remove the dryer belt and try turning the drum by hand. If the drum still makes a squealing or grinding sound, the drum bearing needs to be replaced.
