How to Fix a Noisy Dryer: Squealing, Thumping, Grinding, and Rattling (2026)
Dryer noise is almost always a mechanical problem — worn drum support rollers, a failed drum bearing or felt seal, or a loose item in the drum. This guide covers diagnosing each noise type and the correct repair.
Fix a noisy dryer by noise type: (1) High-pitched squealing: the drum bearing or drum felt seal is worn. The felt seal wraps around the front of the drum and acts as a sliding surface — when worn, the drum metal contacts the front bulkhead directly and squeals. Replace the felt seal and the drum glides. (2) Thumping that worsens over time: drum support rollers (small wheels at the back of the drum) are worn flat. Replace all rollers at once — they wear together. (3) Grinding or scraping: a foreign object (coin, bra underwire, button) has escaped the drum and is lodged between the drum and the front or rear panel. (4) Rattling from the body: loose front or rear panel screws.
Frequently Asked Questions
What causes a squealing noise from a dryer?
Dryer squealing diagnosis: (1) Drum felt seal (front seal) — the most common cause of dryer squealing. A strip of high-temperature felt runs around the front opening of the drum. The drum rotates against this felt seal, which provides a sliding surface and a seal. When the felt wears thin, the metal drum edge contacts the plastic or metal front bulkhead directly, creating a high-pitched squeal. The squeal is constant while the dryer runs and typically gets louder over time. (2) Drum bearing (rear bearing) — some dryers have a central shaft and bearing at the back of the drum. When the bearing fails, it creates a squealing or grinding sound that may vary with drum load. (3) Idler pulley — the idler pulley maintains belt tension on the drive belt. A worn idler pulley bearing squeals, often with a rhythmic quality tied to belt rotation speed. (4) Motor bearing — less common, the motor itself can squeal when its bearings fail. Motor bearing noise is consistent throughout the run and does not change with drum position. (5) Diagnosis: open the dryer door and spin the drum by hand. Squealing while hand-spinning (without the motor running) points to the felt seal or drum bearing. Squealing only when running (belt and motor turning) points to the idler pulley or motor bearing.
How do I fix thumping in a dryer?
Dryer thumping repair: (1) Thumping that occurs rhythmically during the cycle — typically once or twice per drum rotation — is caused by worn drum support rollers. The rollers are small nylon wheels (2–3 inches in diameter) on the rear bulkhead or base that support the drum's weight as it rotates. When the nylon wears flat in one spot, the drum bumps over the flat spot once per revolution. (2) Confirm by opening the door and spinning the drum by hand: if the drum thumps or catches at a regular point in its rotation, the rollers are worn. (3) Replacement: unplug the dryer. Remove the front panel (usually 2–3 screws at the bottom and clips at the top). Remove the belt from the drum. Lift the drum out. The rollers are on the rear bulkhead — remove the retaining clip (snap ring) and slide the old roller off the shaft. Press the new roller on and reinstall the snap ring. (4) Replace all rollers at the same time: if one roller is worn, the others are also near failure. Dryer roller kits ($10–$20) include all rollers for the model. (5) Also replace the drive belt and idler pulley while the dryer is open — these are inexpensive parts and save a second disassembly later.
How do I fix a grinding or scraping noise in a dryer?
Dryer grinding or scraping repair: (1) A grinding or scraping sound, especially one that changes when you change the drum load, is usually a foreign object caught between the drum and the front panel. Coins, bra underwires, buttons, and small hardware items are common culprits. (2) Check the drum first: run the dryer for a few seconds with the door open (prop the door switch closed with a small screwdriver or tape — see model-specific instructions). Watch whether the sound comes from the front edge of the drum. (3) Locating the object: unplug the dryer. Remove the front panel as described above. Inspect the area between the drum edge and the front bulkhead. The object is often visible. (4) For persistent grinding after clearing debris: inspect the drum glides (small nylon pads on the front bulkhead that the drum rides on). If the glides are worn through, the metal drum edge grinds directly on the metal bulkhead. Replace the drum glides — a kit for most models is $5–$15. (5) Drum baffles: the metal fins inside the drum that tumble clothes can also crack and create grinding sounds as the loose baffle edge drags. Inspect the interior drum baffles and replace any that are cracked or loose.
How much does it cost to fix a noisy dryer?
Dryer noise repair cost: (1) Drum felt seal and drum glides: $10–$20 for the parts kit. Labor: 45–60 minutes for a DIY repair. Main skill needed: removing the front panel. (2) Drum support rollers: $10–$20 for a full roller kit. Same disassembly as the felt seal repair — do both at the same time. (3) Idler pulley: $10–$20. Often replaced as a kit with the belt and rollers — the 'dryer maintenance kit' for most models. (4) Belt: $10–$15. A worn belt can also cause slapping or squealing sounds in addition to the common 'belt breaks — drum stops' failure. (5) Professional repair: an appliance technician visit typically costs $100–$150 for labor plus parts. For a dryer under 5 years old with a squealing drum seal or worn rollers, DIY repair is clearly economical. For a dryer over 10 years old: compare repair cost to replacement. (6) Finding parts: use the model number (inside the door jamb or back panel) to look up exact part numbers at AppliancePartsPros, RepairClinic, or PartSelect. Specify the model to ensure the correct roller diameter and felt seal profile.
How do I access the inside of my dryer to fix the noise?
Dryer disassembly overview for drum repairs: (1) Unplug the dryer before any disassembly. For gas dryers: also close the gas shutoff valve and note the gas connection when repositioning the dryer. (2) Remove the lint screen and lift the top panel: on most dryers, two screws are behind the lint screen access, or the top panel is released by inserting a putty knife 2–3 inches from each corner to depress spring clips. (3) Disconnect the door switch wire harness (usually a quick-disconnect connector) before removing the front panel. (4) Remove the front panel screws (typically 2 at the bottom corners and 1–2 at the top after the top panel is raised). The front panel pivots forward and off. (5) The drum is now accessible. The drive belt loops around the drum and around the motor shaft via the idler pulley. Releasing belt tension: push the idler pulley to the side and slip the belt off the motor shaft. Lift the drum straight out. (6) Reassembly is the reverse. Loop the belt around the drum in the correct orientation (ribbed side contacts the drum), then loop it around the motor shaft and under the idler pulley to restore tension. Rotate the drum by hand to confirm the belt is seated correctly before restoring power.
Fix a noisy dryer by noise type: (1) High-pitched squealing: the drum bearing or drum felt seal is worn. The felt seal wraps around the front of the drum and acts as a sliding surface — when worn, the drum metal contacts the front bulkhead directly and squeals.
Replace all drum rollers at the same time — if one is worn, the others are close behind, and the disassembly effort is already done.
What you need
- Dryer drum roller and felt seal kit (search by model number)
- Putty knife (for top panel clips)
- Nut driver or screwdriver
- Belt ($10–$15, replace while open)
Step 1: Identify the noise type
Squealing = felt seal or bearing. Thumping (rhythmic) = drum rollers. Grinding/scraping = foreign object or worn drum glides.
Step 2: Disassemble to access the drum
Unplug and remove the top panel, disconnect door switch harness, remove the front panel. Release belt tension at the idler pulley and lift the drum out.
Step 3: Replace worn parts
Install new drum rollers (replace all), new felt seal and glides, and new belt if it looks cracked or glazed.
Step 4: Reassemble and test
Route the belt around the drum and motor shaft. Replace panels. Run the dryer empty for 5 minutes to confirm the noise is gone.

Diagnose before disassembling: Squealing (constant while running, worse over time) = worn drum felt seal or idler pulley bearing. Thumping (rhythmic, once or twice per drum rotation) = worn drum support rollers. Grinding or scraping = foreign object between drum and panel, or worn drum glides. Rattling from the body = loose front/rear panel screws. Open the door and spin the drum by hand — squealing or thumping when hand-spinning points to the felt seal or rollers, not the motor.
- Access the drum by removing the front panel
Unplug the dryer. On most dryers: remove the lint screen, unscrew 2 screws under the lint screen opening, then insert a putty knife 2–3 inches from each corner of the top panel to release the spring clips and lift the top panel up. Disconnect the door switch wire harness (a quick-connect plug). Remove 2 screws at the bottom corners of the front panel — the panel pivots forward and off. The drum, belt, and rear components are now visible.
- Replace drum support rollers
The rollers are small nylon wheels on the rear bulkhead that support the drum. Release belt tension by pushing the idler pulley to the side and slipping the belt off the motor shaft. Lift the drum out. On the rear bulkhead, remove the snap ring (retaining clip) from each roller shaft and slide off the roller. Press new rollers on and reinstall snap rings. Replace all rollers at once — a full roller kit costs $10–$20 and takes no more time than replacing one.
- Replace the drum felt seal and glides
The drum felt seal is a strip of high-temperature felt around the front drum opening. Peel off the old seal — it is held with adhesive. Apply high-temp adhesive to the front drum lip and press the new felt seal in place, joining at the bottom. The drum glides are small plastic or nylon pads on the front bulkhead that the drum slides against — pry them off and snap or press in the replacements. Replace the belt if it shows cracks or glazing.
- Reassemble and test
With the drum back in position: loop the drive belt around the drum (flat side against drum, ribbed side out), route it under the idler pulley and around the motor shaft. Rotate the drum by hand 2–3 times to confirm the belt is tracking correctly. Reinstall the front panel, top panel, and screws. Reconnect the door switch harness. Plug in and run the dryer empty for 5 minutes — no squealing, thumping, or scraping should remain.
