How to replace a dryer blower wheel
This DIY dryer repair guide explains how to replace a dryer blower wheel. The blower wheel is attached to the drive motor shaft. It spins to blow air throughout the drum and out the exhaust vent. If air isn't moving through the dryer, or if the blower wheel rattles, replace it with a manufacturer-approved dryer part.
The video below shows a gas dryer, but the basic repair is the same. These steps work for Kenmore, Whirlpool, Maytag, Amana, Roper, Crosley and Estate dryers with a lint screen housing located in the top dryer panel.
