Why Is My Dryer Making a Rattling Noise?

Q: Why is my dryer making a rattling noise during the cycle?

A: A rattling noise in a dryer is often caused by a loose object (like coins, buttons, or zippers), a loose vent hose, worn drum supports, or a blower wheel issue. Sometimes it is a simple laundry-item noise, but if the rattling repeats every cycle or gets louder, it may be a mechanical part that needs service before it causes more damage.

Common Symptoms

• Rattling or clanking sound while the drum turns
• Noise changes with load size or item type
• Noise starts and stops during the cycle
• Rattling from behind the dryer or vent area
• Dryer still heats and runs, but sounds loose
• Rattling along with thumping, scraping, or vibration

Safety First

• Turn the dryer off and unplug it before checking the drum and vent connection.
• Do not continue running the dryer if the rattling is loud, metallic, or suddenly worse.
• Do not open internal panels or handle moving/electrical parts unless qualified.
• Stop using the dryer if you smell burning or hear grinding/scraping.

Quick Checks You Can Do (Easiest First)

1. Check pockets and clothing hardware: Coins, keys, belt buckles, zippers, and buttons are common rattling sources.
2. Run a short test with an empty drum: If the rattling disappears, the noise may be from items in the load.
3. Inspect inside the drum: Look for loose objects near drum seams, baffles, and the door opening.
4. Check the lint filter area: Small items can fall into the filter housing or airflow path and make noise.
5. Inspect the vent hose behind the dryer: A loose or vibrating vent hose can rattle against the wall or dryer cabinet.
6. Turn the drum by hand (with power unplugged): Listen for repeated rattles, rubbing, or rough spots.

Most Common Causes

Loose Items in the Drum (Most Common)

Coins, bra wires, snaps, buttons, and zipper pulls can create rattling or clanking sounds, especially in larger loads or mixed fabrics.

Loose or Vibrating Vent Hose

The vent hose behind the dryer can vibrate and rattle against the cabinet or wall, especially if airflow is strong or the hose is not secured well.

Foreign Object in Blower Housing

Small items can sometimes get pulled into the airflow path and rattle in or near the blower wheel housing.

Worn Drum Rollers or Supports

As support rollers wear, they can create extra play and noise that sounds like rattling, rumbling, or light thumping before becoming a bigger issue.

Loose Drum Baffle or Internal Fastener

On some dryers, a drum baffle (lifter) or internal screw can loosen and create a repeated rattling sound as the drum rotates.

Idler Pulley / Belt Vibration

A worn idler pulley or belt-related issue can create rattling or fluttering noises that may come and go during the cycle.

Cabinet Panel Vibration

A loose panel, top, or rear access area can vibrate and rattle, especially during heavier tumbling loads.

What Beacon Usually Checks

When our friendly technicians in yellow inspect a dryer making a rattling noise, we usually check:

• Drum interior for foreign objects and loose baffles
• Lint filter housing and blower path for small items
• Vent hose condition, routing, and vibration points
• Drum rollers, glides, and support wear
• Idler pulley and belt condition
• Cabinet panels and fasteners for vibration/rattle sources
• Overall dryer operation after the noise source is corrected

When to Call Beacon

Call Beacon if the rattling noise happens with an empty drum, repeats every cycle, or is getting louder. A “small” rattle can be an early warning sign of a support part, blower issue, or loose component that can turn into a larger repair if ignored.

Prevent This Next Time

• Check pockets before washing and drying.
• Zip zippers and secure loose clothing hardware when possible.
• Keep the vent hose properly attached and not crushed.
• Don’t ignore new noises that repeat from load to load.
• Schedule dryer maintenance if noises start changing.
