Whirlpool Dryer: thumping noise
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.
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
DIY Solutions
Redistribute or remove heavy/bulky items
- Open dryer
- Redistribute items to avoid large clumps
- Run a small or balanced load to test noise reduction
Level the dryer
- Unplug dryer or turn off power
- Adjust leveling legs until dryer sits flat and stable
- Use a level on top of dryer to confirm level
- Test run to check noise
Inspect and temporarily warm up drum rollers
- Run dryer empty for a few minutes to warm rollers
- Listen if thumping diminishes as rollers regain shape
