A dryer making loud noises is one of the clearest signs that something is failing mechanically. At Appliance Medic Pro, customers often call us after hearing grinding, squealing, thumping, or rattling sounds coming from their dryer.
Ignoring these noises usually leads to bigger damage and higher repair costs, so early diagnosis matters.
Types of Dryer Noises (What We Hear on Service Calls)
-
Squealing or screeching → worn rollers or belt
-
Thumping or banging → flat drum rollers or overloaded drum
-
Grinding or metal noise → failed bearings or idler pulley
-
Rattling → loose objects or screws
-
Buzzing or humming → motor issue
Each sound points to a different internal problem.
Common Reasons Your Dryer Is Making a Loud Noise
1. Worn Drum Rollers (Most Common)
From real-world experience, drum rollers wear out on most dryers after years of use.
Signs:
-
Loud thumping sound
-
Noise gets worse as the cycle continues
-
The dryer vibrates excessively
👉 We always replace rollers in pairs to prevent repeat failures.
2. Failing Idler Pulley
The idler pulley keeps tension on the dryer belt.
When it fails:
-
High-pitched squealing or screeching noise
-
Noise may stop when the dryer warms up
-
The belt can snap if ignored
3. Dryer Belt Problems
A worn or misaligned belt can:
-
Slap against the drum
-
Cause thumping or squealing
-
Eventually, stop the dryer from turning
4. Objects Stuck Inside the Drum
Coins, screws, bra wires, or buttons often slip through.
We frequently find:
-
Coins stuck in the blower housing
-
Metal scraping sounds
-
Noise starts suddenly after a load
5. Motor Bearings Going Bad (Serious)
If the motor bearings fail:
-
Loud grinding or buzzing noise
-
The dryer may struggle to start
-
A burning smell may appear
⚠️ Motor issues should be handled by a professional.
What You Can Safely Check Yourself
Before calling a technician:
✅ Remove all items from the drum
✅ Check the lint trap for loose debris
✅ Listen to identify the type of noise
✅ Make sure the dryer is level
❌ Do not run the dryer repeatedly if the noise is loud or metallic.
