Genuine OEM rubber-face cylinder/drum drive belt. It transmits motor power to rotate the dryer cylinder (drum).

Is This the Right Part?

Common Symptoms

• Drum will not rotate
• Drum rotates intermittently or slips
• Visible belt wear, cracking, fraying, or looseness
• Rubbing or rhythmic belt-related noise during drum rotation

Check Before Replacing

• Disconnect electrical power and, for gas models, shut off the gas supply before inspection.
• With power disconnected, turn the drum by hand and note whether it rotates freely; abnormal resistance may indicate a separate drive-system problem.
• Visually inspect the accessible belt path for breaks, fraying, cracking, glazing, looseness, or displacement from the drum and pulleys.
• If the drum does not rotate, inspect the belt together with the idler and motor-pulley area rather than assuming the belt is the only fault.
