The part(s) or condition(s) listed below for the symptom Dryer makes noise are ordered from most likely to least likely to occur. Check or test each item, starting with the items at the top of the page.
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.
Dryer drum drive belt, 100 inches long, 3/8" wide,5 ribs 4 grooves. The drive belt wraps all the way around the dryer drum, around a tension pulley, and then around the drive motor pulley. If the drum will not turn when the dryer is turned on the belt is likely broken.
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.)
Dryer drum support roller kit. Includes two washers. When the drum rollers are worn out, they can cause the dryer to make a loud rumbling noise. Both rollers should be replaced at the same time. The roller does not need lubrication, the bearing is self lubricanting.
One or more of the drum roller axles might be worn out. 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. Over time, the drum rollers and axles wear out, causing the dryer to make a loud rumbling noise. To determine if the drum roller axles 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, the axles 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.
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.
The drum glides (also called slides) might be worn out. The drum glides are small plastic pieces that support the front of the dryer drum. As the drum rotates, it slides on these plastic pieces. Over time, the drum glides wear out. If the drum glides are worn out, the dryer will make noise. To determine if the drum glides are worn out, inspect them for wear. If one or more glides are worn out, replace all of the glides as a set.
Inspect the idler pulley for signs of wear. If the idler pulley is worn or damaged, we recommend replacing the drive belt in addition to replacing the idler pulley.
The drive motor bearings might be worn out. However, this is rarely the case. Before replacing the drive motor, check all the more commonly defective parts. If you have determined that all of the other components are working properly, replace the drive motor.
