Why Is My Dryer Making Loud Noises? Common Causes & What To Do

A noisy dryer can quickly turn laundry day into a headache.

If you’ve noticed your dryer making loud or unusual sounds, addressing the issue before it leads to bigger problems or disrupts your household routine is important.

Here’s a breakdown of what might be causing those noises, how to diagnose them, and when to call the experts.

Understanding Normal vs. Problematic Dryer Noises

Every dryer makes some sound during operation, but loud banging, grinding, or squealing noises are not normal. These sounds often indicate a mechanical issue or a part that needs repair or replacement. Ignoring them can lead to more extensive damage and costly repairs down the line.

Common Causes of Loud Dryer Noises

• Foreign Objects in the Drum: Coins, keys, or buttons left in pockets can rattle or bang around the drum.

• Worn or Damaged Parts: Over time, drum rollers, bearings, and glides can wear out, causing grinding, squeaking, or thumping sounds.

• Idler Pulley Issues: A failing idler pulley can result in high-pitched squealing or screeching noises.

• Drive Belt Problems: A frayed or damaged belt may create a thumping or slapping sound as the drum turns.

• Blower Wheel Obstructions: You might hear rumbling or vibrating if the blower wheel is loose or blocked.

• Unbalanced or Overloaded Loads: Overloading the dryer or unevenly distributing clothes can cause banging or thumping.

• Unlevel Dryer Legs: If your dryer isn’t sitting level, it can vibrate or rattle during use.

• Failing Motor: A loud humming or buzzing may signal a motor issue that requires professional attention.

Diagnosing the Type of Noise

• Rattling: Usually caused by loose items or hardware.

• Squeaking/Squealing: Often points to worn rollers or a faulty idler pulley.

• Grinding: Typically a sign of worn bearings or glides.

• Thumping: May result from an unbalanced load or worn rollers.

• Rumbling: Often linked to blower wheel issues.

• Humming: Can indicate a failing motor.

Troubleshooting Steps You Can Take

• Check and remove any foreign objects from the drum and lint trap.

• Make sure the dryer is level and adjust the legs if necessary.

• Avoid overloading the dryer and distribute laundry evenly.

• If you’re comfortable, inspect visible parts for signs of wear, such as a frayed belt or loose hardware.

For internal repairs, like replacing rollers, bearings, or the motor, it’s best to call a professional. Attempting complex repairs without the proper tools or expertise can lead to further damage or safety risks.

Preventing Future Dryer Noises

• Always check pockets before starting a load.

• Avoid overloading the dryer and distribute items evenly.

• Schedule regular maintenance and cleaning, including the lint trap and vent.

• Address minor noises early to prevent larger repairs.
