Use this guide to replace the idler pulley on your Whirlpool Duet WED87HED dryer. This pulley provides tension to the drive belt. If it fails, the dryer will not spin properly, and the drive belt will likely break. Usually, this part makes squeaking and grinding noises when it's failing. The motor may also overheat because the belt is hard to move. Although the photos in this guide show the blower housing removed from the machine, this is mainly for clarity. You don't need to remove the blower housing to perform this repair.
