Most Frequent Causes for Dryer makes noise

Cause 1Drive Belt

The drive belt is a very long, slender belt that wraps all the way around the dryer drum, around a tension pulley, and then around the drive motor. Over time, the drive belt can become frayed or otherwise damaged. If the drive belt is frayed or damaged, the dryer will be noisy as it turns. Inspect the drive belt for signs of wear. If the drive belt is worn, replace it.

If the drum will not turn when the dryer is turned on the belt is likely broken.

Cause 2Drum Roller

One or more of the drum rollers might be worn out. Many dryers have two drum support rollers on the rear of the drum, and some dryers have two more rollers supporting the front of the drum. When the drum rollers are worn out, they can cause the dryer to make a loud rumbling noise. To determine if the rollers are worn out, inspect the rollers. If one or more of the rollers are severely worn, we recommend replacing all of the rollers at the same time as a preventative measure. (The roller shaft can often be reused if it is in good condition. Clean the shaft thoroughly before installing the new rollers.)

Cause 3Blower Wheel

The blower wheel draws air through the dryer and pushes the air out the vent. Clumps of lint, socks, and small articles of clothing can escape the lint filter and get caught in the blower wheel. If an object is caught in the blower wheel, the dryer may make noise. In addition, the blower wheel sleeve can wear out, allowing the blower wheel to wobble on the motor shaft. To determine if the blower wheel is working properly, remove the dryer vent and assess the strength of the air flow. If the air flow is weak, check the blower wheel for obstructions. If no obstructions are present, try rotating the blower wheel by hand. If the blower wheel wobbles as it turns, replace it.

Cause 4Drum Support Roller & Axle

Most dryers have two drum support rollers on the rear of the drum, and some dryers have two more rollers supporting the front of the drum. The rollers must spin freely to work properly. Over time, the drum roller axles can wear out, causing the rollers to bind. If the rollers are worn out or start binding, the dryer may make a loud rumbling noise. To determine if the support rollers are worn out, remove the belt from the dryer and try turning the drum by hand. If the drum does not rotate freely, check the support rollers for wear. If the rollers spin freely without wobbling, they do not need to be replaced. If a roller wobbles and/or does not spin freely, we recommend replacing all of the axles and rollers as a preventative measure.
