Belt Specifications This authentic OEM drum belt is designed to fit with various models of dryers. The belt is a narrow strip of rubber that wraps around the drum and connects it to the dryer motor. This allows the drum to rotate smoothly and circulate warm air evenly through the drum. If the drum belt is faulty the drum will be unable to turn, you may hear unusual grinding, scraping a banging noise, and the belt itself may be frayed, cracked, or hanging loosely off the drum. If the belt is no longer able to support the drum, it should be replaced promptly to prevent further damage to the dryer and ensure it continues to run efficiently.
