Dryer making noise that changes with drum speed: What to check next

Use only checks that match the exact appliance or system and its official guide.

1. Check 1

   Stop the cycle, turn the dryer off, and let the drum come to a complete stop. From outside the appliance, record whether the sound is a rattle, thump, scrape, squeal, grinding, rumble, hum, or a click, and whether it changes with drum speed or only during heating.

   Expected result: There is no smoke, burning smell, sparking, gas odor, damaged cord, or drum that has stopped turning unexpectedly; the sound can be described without opening the dryer.

   Next step: If any hazard is present, keep the dryer off and arrange appropriate emergency or qualified service help. Otherwise continue with the dryer unplugged or otherwise isolated from operation while making the visual checks below.

   Stop if: Do not restart a dryer that smokes, smells of gas or burning insulation, sparks, has a damaged power cord, or has a drum that binds or will not turn normally.

   Why this matters

   Why: A speed-linked mechanical sound can be investigated with safe external checks. A combustion, electrical, or severe mechanical warning is a stop-use condition, not a normal noise diagnosis.

2. Check 2

   Remove all laundry and loose items, close the door, and make one brief empty-drum observation from outside the dryer using the same cycle conditions; do not reach through the door or run the dryer with a panel removed.

   Expected result: The noise disappears when empty, becomes quieter, or remains at the same speed-linked pattern with no load inside.

   Next step: Use the loaded-versus-empty result to choose the matching branch; stop repeated testing if the sound is scraping, grinding, or worsening.

   Stop if: Do not keep operating the dryer to reproduce a severe noise, and never place hands or tools inside while the drum can move.

   Why this matters

   Why: A noise that disappears with an empty drum makes load contact, overload, a balled-up item, or a garment fastener more likely. A noise that remains with an empty drum shifts concern toward the dryer mechanism or blower path and is less likely to be laundry alone.

3. Check 3

   With the dryer off and stopped, inspect the empty drum, the front and rear drum edges, and the door seal area for coins, paper clips, pens, buttons, zippers, screws, or other objects; check the last load for tangled sheets, oversized fasteners, shoes, or unusually heavy wet items.

   Expected result: An object is lodged at a drum edge or seal, the load was knotted or overloaded, the sound matches a hard item tumbling, or no load-related cause is visible.

   Next step: Remove only a loose, reachable item without force, clear pockets, separate the load, and retest once with a balanced lighter load. If an object is trapped or the noise persists with a clear drum, arrange service.

   Stop if: Do not pry an object from the seal, scrape the drum, reach into a narrow opening, or remove any panel to retrieve it.

   Why this matters

   Why: Small hardware at the drum seam can scrape as the drum rotates, while fasteners and a balled-up or heavy load can rattle or thump. If the drum and load are clear, do not assume the next step is to remove a support or belt.

4. Check 4

   From a stable position, check that the dryer is on a solid floor with all intended feet in contact, and clear objects leaning against it, items on top, pedestal contents, and contact with the washer, wall, cord, or exposed vent connection.

   Expected result: The cabinet rocks, a foot is missing or loose, the dryer touches another object, the vent or cord can rattle against a surface, or the installation is stable and clear.

   Next step: Remove only loose external items and correct an obvious safe contact or leveling issue according to the installation instructions; then make one short observation. Request service if the cabinet cannot be stabilized without moving connections or if the noise remains.

   Stop if: Do not pull out a gas dryer, disconnect gas or vent connections, lift the appliance, or work behind it without qualified help.

   Why this matters

   Why: Leveling and external contact can add pounding, vibration, or rattling that changes as the cabinet and drum move. A stable installation makes an internal rotating symptom more likely when the noise continues.

5. Check 5

   With the dryer off, remove the lint screen and look only into the accessible lint-screen opening for a visible foreign object; also observe from outside whether the vent connection is secure and free from rattling contact. Keep the lint screen installed whenever the dryer operates.

   Expected result: A coin, sock, button, or other object is visible in the lint path, the vent is loose or touching something, or the accessible path is clear.

   Next step: Remove only an object that is plainly reachable with the dryer-specific lint brush or ordinary safe access; otherwise record the finding and ask a qualified servicer to inspect the internal path.

   Stop if: Do not insert tools or hands past a sharp or narrow opening, remove the blower housing, disconnect the vent for an internal inspection, or operate without the lint screen.

   Why this matters

   Why: A foreign object in the lint path can strike the blower wheel and create a rotating rattle. A loose vent can make a separate vibration that is mistaken for an internal dryer fault; a clear accessible path does not rule out an internal blower or belt issue.

6. Check 6

   Combine the empty-drum result, sound type, location, installation checks, and trend to choose whether to stop use and request appliance service; provide a short recording or written description only from a safe position.

   Expected result: The noise is gone after a loose item, load, or external-contact correction; or it remains empty, is a scrape or grind, comes from the front or rear, becomes louder, or is accompanied by drum drag, burning odor, smoke, or another fault.

   Next step: Stop using the dryer and arrange qualified appliance service for a persistent empty-drum noise, grinding, scraping, worsening squeal or rumble, or any hazard. Tell the technician whether the noise follows drum speed, whether the drum was empty, and where it was loudest.

   Stop if: Do not remove cabinet panels, test energized wiring, bypass a door or safety switch, lubricate an unknown part, or replace a belt, roller, pulley, bearing, glide, or blower component based only on sound.

   Why this matters

   Why: A resolved load or contact symptom supports normal use with the preventive correction. A persistent empty-drum or harsh rotating noise is consistent with a worn or obstructed mechanical path, but the exact part and repair method are model-dependent.
