Drum Belt

This drum belt, often referred to as a drive belt, is used in the assembly of dryers. It goes around the drum, the idler pulley, and the motor pulley. As the armature on the motor spins, this belt is what rotates the drum and tumbles your clothes during the dry cycle. If you can hear the motor running but the drum is not moving that is a sign your belt is broken, stretched, or damaged, and can no longer grip the drum. This belt is 87 3/4 inches long, and is 1/4 inch wide. Because it is made of rubber it is common for this part to become brittle and need to be replaced. This is an authentic OEM replacement part, and it is sold individually. Remember to unplug your dryer before you begin repair work.
