Kenmore Dryer: whirring noise when hot

Professional Repair Guide

What is this symptom?

If your Kenmore dryer is producing a whirring noise during the heated portion of the drying cycle, it's likely not normal. This louder-than-usual sound can indicate issues such as worn drum support rollers, a damaged blower wheel, or even foreign objects obstructing the blower housing. Addressing this issue promptly can prevent further damage and ensure efficient drying.

Urgency: Medium

Important Tips for Kenmore Models

  • Rollers, blower wheel, belt and idler pulley commonly identified in Kenmore dryer noise diagnoses.
  • Kenmore-specific repair kits often combine belt, idler, and roller parts for comprehensive fix.

Possible Causes

Worn drum support rollers

How to Identify: Whirring or rumbling noise increases as drum spins; noise louder when drum loaded; manual rotation of drum feels rough or uneven.

Part: Drum support rollers

Worn or damaged blower wheel

How to Identify: Noise often accompanied by reduced airflow out the vent; whirring can be due to wobble or blockage around blower housing.

Part: Blower wheel

Worn belt or belt tension issues

How to Identify: Whirring may vary with drum speed; visually frayed or cracked belt; idler pulley may squeal before whirring.

Part: Drive belt / idler pulley

Dryer motor bearings wear

How to Identify: Whirring mixed with grinding or humming; noise increases under load; drum hard to turn manually without belt.

Part: Drive motor

Foreign objects in blower housing or drum

How to Identify: Rattling mixed with whirring; items visible in vent or blower area; emptier pockets still produce noise.

Part: Interior debris
