Symptoms
- High-pitched squeak in rhythm with drum turning
- Noise gets louder with a full load
- Squealing on startup that may fade slightly
- Noise present even when empty
Likely causes
- CommonWorn drum support rollersThe rollers the drum rests on develop flat spots or dry bearings that squeak as they turn.
- CommonDry or worn idler pulleyThis pulley tensions the drive belt and its bearing can wear out, causing a squeal.
- PossibleWorn drive beltA glazed or frayed belt can squeak against the drum or pulleys.
- PossibleWorn drum glides or felt sealSmall felt or plastic pads that the drum rides on can wear thin and squeak.
- Less commonMotor bearing wearA failing motor bearing causes a persistent squeal even when the drum isn't loaded.
What to do
- Unplug the dryer before doing any inspection inside the cabinet.
- Remove the front or top panel per your model to access the drum, belt, and rollers (check a repair guide for your model first).
- Spin the drum by hand and listen for the squeak's source, which narrows down rollers versus pulley.
- Inspect the rollers for flat spots or wobble and the idler pulley for wear or looseness.
- Apply a small amount of appliance-grade grease to roller shafts if they're just dry, not worn out.
- Replace visibly worn rollers, the idler pulley, or the belt as a set since they wear together.
- If you're not comfortable opening the cabinet, describe the noise timing to a technician for a faster diagnosis.
