Kenmore Dryer: screeching noise on startup

Professional Repair Guide

What is this symptom?

Is your Kenmore dryer making a screeching noise on startup? This high-pitched sound typically occurs when the drum begins to turn, signaling friction in components. Common causes include a worn idler pulley, cracked drive belt, or dry drum support rollers. Addressing these issues promptly can prevent further damage and ensure efficient operation.

Important Tips for Kenmore Models

  • Common causes such as worn idler pulley, belt, rollers, and bearings are also applicable to Kenmore dryers; replacement parts often sourced by model number.

Possible Causes

Worn idler pulley or pulley bearing

How to Identify: Squealing/friction noise starts immediately at startup and continues as drum spins; pulley wheel may feel stiff when spun by hand.

Part: Idler pulley

Worn or cracked drive belt

How to Identify: High‑pitched squeal that may vary with drum load; inspect belt for fraying, cracks, or glazing.

Part: Drive belt

Dry or worn drum support rollers

How to Identify: Noise accompanied by uneven drum movement or wobble; rollers may not spin freely when tested manually.

Part: Drum support rollers

Worn drum bearings or glides

How to Identify: Noise occurs at startup and continues; drum may feel rough when rotated by hand, particularly near the rear.

Part: Drum bearings/drum glides

Motor bearing wear

How to Identify: Squealing persists even after replacing belt/pulleys; motor may sound noisy independently of drum movement.

Part: Dryer motor
