Whirlpool Dryer: thumping noise

Professional Repair Guide

What is this symptom?

If your Whirlpool dryer is making a thumping noise during the dry cycle, it could indicate several issues. This rhythmic sound may occur with heavy or unbalanced loads, or after a period of non-use. Accompanied by vibrations, this noise typically stems from fabric balls tumbling, worn drum rollers, or loose drum support glides. Addressing these issues promptly can improve your dryer's performance and prevent further damage.

Urgency: Medium

Important Tips for Whirlpool Models

  • Whirlpool specifically notes that thumping can occur after long non-use due to flattened support rollers and normalizes after running for a short time

Possible Causes

Ball of fabric or heavy items tumbling

How to Identify: Thumping occurs only with heavy/bulky loads (e.g., sheets, tennis shoes and stops when load redistributed or removed

Part: Drum load

Worn internal drum rollers or axles

How to Identify: Persistent thumping regardless of load; drum feels rough when spun by hand with power off

Part: Internal drum rollers/axles

Loose or damaged drum support glides

How to Identify: Drum may slightly sag or make inconsistent thumping rather than uniform rhythm; inspection shows worn glides

Part: Drum support glides/slides
