It’s normal for a dryer to make some sound while running, especially as the drum turns. However, if the noise suddenly becomes louder or unusual, it can be concerning. In many cases, the cause is simple — such as items trapped inside the drum or worn support parts.
While unusual sounds shouldn’t be ignored, they often have manageable causes.
The Most Common Reasons This Happens
1. Loose Items in the Drum
Coins, buttons, or small hard objects left in pockets can rattle inside the drum during a cycle. This often creates a tapping or knocking sound.
Checking clothing pockets before washing helps prevent this.
2. Worn Drum Rollers or Bearings
Over time, the parts that support the drum can wear down. This may cause squeaking, grinding, or rumbling noises.

3. Loose Internal Components
Screws or panels may loosen over time, especially in older units. This can create vibrating or buzzing sounds.
4. Unstable Placement
If the dryer isn’t level, vibrations can become louder during operation.
Ensuring all feet are firmly adjusted may reduce the noise.
5. Belt or Motor Issues
A worn drive belt or motor component can create squealing or scraping sounds.

Is This Normal?
Some noise is expected during drying cycles.
It may be normal if:
• The sound is consistent each cycle
• The dryer functions normally otherwise
• The noise is mild and doesn’t worsen
It may not be normal if:
• Grinding or metal scraping occurs
• The noise increases over time
• The dryer vibrates excessively
When Should You Worry?
You should investigate further if:
• The noise becomes significantly louder
• The drum feels loose
• The dryer stops mid-cycle
• Burning smells occur
Persistent mechanical noises may require repair.
What You Can Do
If your dryer is making noise, you can:
• Check for loose items inside the drum
• Ensure the dryer is level
• Clean the lint filter
• Monitor changes in sound patterns
• Avoid overloading
If unusual noises continue or worsen, professional inspection may be necessary.
In most situations, dryer noise is caused by minor mechanical wear or loose items rather than serious failure. Simple checks often reduce the sound. If the noise persists, a technician can assess internal components.
