The Whirlpool WP95405 Washing Machine Drive Belt is a vital component for keeping your washer running properly. Underneath the washer is a looped rubber belt that connects the drive system pulley and the motor pulley. The drive system pulley moves when the washer motor rotates, which also rotates the drive belt. The washer basket rotates as a result of this pulley's connection, cleaning your garments. The effectiveness of your washer might be greatly impacted by a worn-out or damaged drive belt. The washer may exhibit odd thumping noises during the spin cycle, take an abnormally lengthy time to wash clothing, or fail to get the garments completely clean.
