Dryer Drive Belt
The drive belt is a high-friction consumable that experiences continuous cyclic loading and thermal stress. Over time, the rubber polymer undergoes heat-aging and loses elasticity, leading to a transverse fracture that severs the mechanical connection between the motor pulley and the drum circumference.

Idler Pulley Assembly
The idler pulley maintains the necessary tension for the belt to grip the drum. If the internal sleeve bearing seizes due to lubricant depletion or lint contamination, it creates a static friction point that either prevents the belt from moving or generates enough localized heat to melt through the belt during motor activation.

Drive Motor
The drive motor utilizes a centrifugal switch to engage the heater only when the drum reaches functional RPM. If the motor's start windings fail or the internal switch becomes fouled with debris, the motor cannot generate the torque required to overcome the drum's inertia, resulting in a 'no-turn' condition.
