Possible Causes

Worn or failing drum support rollers

How to Identify: A whirring or grinding noise that transitions into movement as the drum spins; inspecting by rotating the drum manually may reveal resistance or roughness in rollers.

Part: Drum support rollers

Clogged or off‑balance blower wheel

How to Identify: Noise coming from bottom/front area of dryer; visible lint/debris in blower wheel; imbalance when spun by hand.

Part: Blower wheel

Drive belt slipping or worn

How to Identify: Whirring or squealing at start that may ease as belt catches; visible wear or fraying on belt inspection.

Part: Drive belt

Idler pulley / belt tension assembly wear

How to Identify: High‑pitched whirring/squealing when belt tension is insufficient; inspect pulley spin by hand and look for grooves or rough motion.

Part: Idler pulley / tensioner

Motor electrical humming or delayed start motor

How to Identify: Persistent hum without immediate drum spin, longer delay at start button press.

Part: Drive motor / start windings
