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
