Dryer Squeaking: Causes and How to Fix It

A squeaking or squealing dryer is almost always caused by worn mechanical parts — the drum felt seal, idler pulley, drum support rollers, or rear drum bearing. The noise usually starts gradually and gets louder over time. The good news: most of these parts cost $10–$40 and the repair takes about an hour with basic tools.

Common Symptoms

Loud squeaking or squealing noise during the drying cycle
Noise that gets worse as the drum heats up
Grinding or rumbling sound that changes with load size
Squeaking that started gradually and progressively worsened
Noise heard mainly when the drum is rotating

Most Likely Causes

1
Worn Drum Felt Seal (Most Common)
A felt or rubber seal runs around the front and rear of the drum to keep clothes inside and maintain airflow. When this seal wears out, the metal drum rubs directly against the cabinet, creating a loud squealing or scraping noise. This is the most common cause in dryers over 5 years old.
2
Worn Drum Support Rollers
Most dryers have 2–4 drum support rollers that the drum rests on. When these rollers wear flat or seize, they create a squeaking, thumping, or grinding noise. If one roller fails, replace all of them at the same time since they wear at the same rate.
3
Worn Idler Pulley
The idler pulley maintains tension on the drive belt that spins the drum. A worn or seized idler pulley produces a high-pitched squealing noise. It should spin freely with no wobble — inspect it when the front panel is removed.
4
Failed Rear Drum Bearing
The rear drum bearing supports the back of the drum. When it wears, the drum wobbles and creates a loud squealing or grinding noise that worsens over time. Some dryers use a ball-and-socket bearing; others use support rollers.

Caution

Always unplug the dryer before removing any panels or working on internal components. For gas dryers, also shut off the gas supply valve at the wall.

1Run the dryer empty for 60 seconds and listen. Noise that stops without a load points to loose items in the drum, not internal parts.
2Unplug the dryer. Remove the front panel (most brands: remove the lint screen, unscrew access points behind it, lift the top, disconnect the door switch). Inspect the felt drum seal — it should be thick and springy, not flat or crumbling.
3Slip the drive belt off the idler pulley and spin the drum by hand. If it grinds, wobbles, or is rough, the rear bearing or support rollers are worn.

4Inspect the idler pulley: it should spin freely on its axle with no wobble or stiffness. A stiff or wobbly pulley needs replacement.
5Replace all drum support rollers as a set. Apply a small amount of appliance lubricant (not WD-40) to metal shaft rollers after installation.

Repair vs Replace

✓ Worth Repairing

Squeaking repairs are among the most cost-effective appliance DIY jobs. Replacing all drum rollers, the felt seal, and the idler pulley together typically costs under $60 in parts. Only consider replacement if the dryer is also failing to heat, the drum itself is cracked, or the unit is over 12 years old with multiple failures.
