Observe: Drum rollers may be worn, cracked, or wobbling.
Means: Worn drum rollers are a common cause of grinding noises.
Next: Replace the drum rollers if damaged
Check the Idler Pulley
Do: Locate the idler pulley near the drum rollers. Spin it by hand to check for smooth movement.
Observe: The idler pulley may make a grinding noise or feel rough when spun.
Means: A faulty idler pulley can cause grinding sounds during operation.
Next: Replace the idler pulley if defective
Examine the Drive Motor
Do: Access the drive motor and check for signs of wear or damage.
Observe: The motor may have worn bearings or other internal damage.

Next: Replace the drive motor if necessary
Inspect the Drum Bearings
Do: Check the drum bearings for wear or damage. These are located at the rear of the drum.
Observe: Drum bearings may be worn or damaged.
Means: Worn drum bearings can cause a grinding noise as the drum rotates.
Next: Replace the drum bearings if damaged
Test the Dryer

FAQ

How long does it take to replace drum rollers?

Replacing drum rollers typically takes 1–2 hours, depending on your experience and the dryer model.

Can I use third-party replacement parts?

Yes, but ensure they are compatible with your Kenmore dryer model for proper fit and function.
