Clothes dryers make many sounds during use, including thumping, whirring and clicking. These sounds happen for a variety of reasons, but if the dryer is making a squeaking noise, this may be a sign that there is something wrong. While the reason for the sound might be minor or major in scope, it is almost always worth investigating.
New Dryer Sounds
Immediately after a dryer has been installed, it is common for it to make unusual noises during the first cycle. This includes a squeaking or squealing noise. However, this noise should go away quickly, usually after the first or second load.
Items that fall out of pockets or other items can tumble around the dryer, making noise. If that same item gets caught in the seal between the dryer tub and the dryer housing, it can create a squeaking noise as the tub continues to try to rotate. Turn off and unplug the dryer, and examine the dryer closely, using a flashlight if necessary. Look at the edges of the tub and see if any objects are evident. If so, remove the object if possible.
Dryers use a system of components that support the drum, including the idler pulley, glides and rear drum bearing. These are all mechanisms that can create noise if damaged or broken, including a squealing sound. Note that these issues will require professional repair or replacement. Contact your dryer manufacturer or a service technician for assistance.
The blower wheel is responsible for moving the air through the dryer and can eventually get worn out or dirty. You can try to clean the blower wheel yourself, or you may need to contact a professional to clean, replace or repair the blower wheel as needed.
