How to replace a dryer drive belt
This DIY dryer repair guide has step-by-step instructions for replacing a broken dryer belt. The dryer drive belt turns the dryer drum when the drive motor turns. If the drive belt breaks, the motor runs, but the drum won't move. You can easily check whether the drive belt is broken by lifting the top and inspecting the belt. Replace a damaged or broken drive belt with the manufacturer-approved dryer part.
The video below shows how to replace a broken drive belt in a gas dryer, but the repair steps are the same for electric dryers. This repair procedure covers Kenmore, Whirlpool, Maytag, Amana, Roper, Crosley and Estate dryers with a lint screen housing located in the top dryer panel.
