Dryer Making a Loud Noise: Common Causes by Sound

Quick Answer

If your dryer is making a loud noise, the possible cause depends on what the sound is like, when it occurs, and whether it happens with an empty or loaded drum.

Some noises come from forgotten objects in pockets, heavy laundry loads, external vibrations, or an unlevel dryer.

Others may indicate worn internal components, such as drum rollers, the idler pulley, drive belt, drum bearings, or blower wheel.

Start by identifying the sound:

| Type of Noise | What It Sounds Like | Possible Causes | Level of Concern |

| Squealing / Squeaking | High-pitched squeal or chirping | Belt, pulley, rollers, or bearings | Investigate if persistent |

| Thumping | Repetitive, low-pitched banging | Heavy laundry, uneven load, or worn rollers | May have a simple cause |

| Grinding | Harsh scraping or metal-on-metal friction | Bearings, drum supports, glides, or a trapped object | Stop using the dryer |

| Rattling | Loose objects shaking or vibrating | Coins, zippers, external objects, or vent duct | Often a simple cause |

| Humming | Continuous, low-pitched hum | Motor, blower, compressor, or pump | Depends on the behavior |

What to check first:

Identify which of these five sounds most closely matches the noise.

Notice whether the sound started suddenly.

Stop the cycle if you hear severe metallic grinding or experience abnormal vibration.

Check pockets and look for loose objects inside the drum.

Make sure the laundry load is not excessively heavy.

Look for objects touching the outside of the dryer.

Check the appliance's visible alignment and stability.

See whether the exhaust duct is vibrating against the cabinet.

Consult the owner's manual for sounds considered normal for your model.

Arrange professional service if the noise persists without an obvious, simple cause.

Safety warning: Stop using the dryer if you hear severe grinding, violent banging, notice a burning smell, see smoke, experience abnormal overheating, or suspect an electrical or gas-related problem.

Do not continue running cycles just to determine which internal component may be damaged.

Why Is My Dryer Making Noise?

A clothes dryer contains several moving parts.

In conventional dryers, a motor drives the system that rotates the drum, while a blower moves air through the appliance.

Depending on the model, the drum may be supported by rollers, bearings, or sliding surfaces.

Common components include:

  • Drive motor.
  • Dryer drum.
  • Drive belt.
  • Idler pulley.
  • Drum support rollers.
  • Drum bearings.
  • Drum glides.
  • Blower wheel.
  • Exhaust ventilation system.
  • Heating and control components.

These components can produce sound during normal operation.

However, wear, misalignment, trapped objects, and oversized laundry loads can change how the dryer sounds.

Start with three questions:

  • What does the noise sound like?
  • When does it occur?
  • Does it disappear or continue throughout the cycle?

No single noise automatically confirms that a particular component is defective.

Normal Dryer Sounds vs. Noises That May Indicate a Problem

A dryer does not have to be completely silent to operate normally.

Sounds from the motor, rotating drum, and moving air are expected.

On gas dryers, clicking sounds may occur as the gas valve operates.

Some heat pump dryers also produce sounds from the compressor or condensate pump.

SituationCan It Be Normal?When to Investigate
Soft, steady hummingYesIf it becomes much louder or changes suddenly
Air moving through the dryerYesIf accompanied by intense vibration or restricted airflow
Occasional clicking in a gas dryerYesIf accompanied by heating problems or other symptoms
Mild thumping after a long period without useOn certain modelsIf it continues or becomes louder
Buttons or zippers tapping the drumYesIf the impacts are excessive or cause damage
Very brief squeal at startupOn certain modelsIf it repeats or continues
Persistent high-pitched squealingUsually requires attentionIf it continues after basic checks
Continuous metallic grindingShould not be ignoredStop using the dryer and arrange service
Violent banging with strong vibrationNoStop using the dryer
Loud humming while the drum is not turningMay indicate a malfunctionStop repeated starting attempts
Burning smell accompanied by noiseNoStop using the dryer immediately

Normal operating sounds vary by manufacturer and dryer design.

A sound considered normal on one model may be unusual on another.

What to Check First

Before considering internal repairs, perform a few simple checks.

Did the Noise Begin With a Particular Load?

If the problem started after loading blankets, sneakers, or heavy clothing, the laundry may be responsible.

Are There Loose Objects?

Coins, keys, buttons, clips, and other small objects can strike the drum during rotation.

Is Anything Touching the Dryer?

Objects placed on top of the appliance, nearby cabinets, the washing machine, or the exhaust duct may create vibration.

Does the Sound Occur Only at Startup?

Some dryers produce temporary thumping after sitting unused for a long time.

A noise that disappears quickly may have a different explanation from one that grows louder during operation.

Is the Drum Turning Normally?

If the motor produces a loud hum but the drum does not rotate, the problem may involve a mechanical or electrical component.

Never force the drum to turn while the dryer is connected to power.

Are There Other Symptoms?

Look for:

  • A burning smell.
  • Smoke.
  • Abnormal heat.
  • Poor drying performance.
  • Strong vibration.
  • Unexpected shutdowns.
  • Error codes.

These warning signs change how urgently the problem should be addressed.

Step-by-Step Dryer Noise Troubleshooting

Step 1: Identify the Type of Sound

Try to classify the noise into one of these categories:

  • Squealing.
  • Thumping.
  • Grinding.
  • Rattling.
  • Humming.

Additional descriptions may include:

  • Clicking.
  • Chirping.
  • Scraping.
  • Rumbling.
  • Buzzing.
  • Pounding.

Your description does not have to be exact.

The goal is to distinguish impacts, vibration, metal-on-metal friction, and motor-like sounds.

If the noise suggests severe friction or another hazard, do not keep the dryer running to listen more closely.

Step 2: Notice When the Noise Occurs

Consider whether it happens:

  • Only when the dryer starts.
  • Throughout drum rotation.
  • With a full drum.
  • With a particular laundry load.
  • When heating begins.
  • During drum direction changes.
  • Near the end of the cycle.
  • When a pump or compressor activates.

If you have already observed a persistent noise, record what you know without running unnecessary additional cycles.

Step 3: Stop the Cycle and Wait for the Drum to Stop

Before inspecting the drum:

  • Stop the drying cycle.
  • Wait until the drum has stopped completely.
  • Allow the dryer to cool.
  • Follow the owner's manual for disconnecting power before maintenance or cleaning.
  • Open the door only when it is safe.

Never reach into a moving drum.

Step 4: Look for Forgotten Objects

With the dryer stopped, check:

  • Clothing pockets.
  • The inside of the drum.
  • Individual garments.
  • The accessible area around the drum opening.
  • Accessories that may be striking the drum.

Look for coins, keys, clips, screws, pens, or other objects.

Important: Lighters and flammable items must never be placed in a dryer.

Remove only visible, accessible objects without inserting tools into internal mechanisms.

Step 5: Check Zippers, Buttons, and Buckles

Metal clothing accessories may repeatedly strike the drum.

To reduce the noise:

  • Close zippers.
  • Fasten loose buttons.
  • Turn garments with metal accessories inside out.
  • Follow clothing care labels.
  • Remove detachable accessories when appropriate.

Do not assume that every repetitive clicking noise indicates a mechanical failure.

Step 6: Check Whether the Load Is Too Heavy

An oversized load can place additional strain on the drum support system.

Look for:

  • Tightly packed clothing.
  • Heavy blankets.
  • Soaking-wet towels.
  • Shoes.
  • Bulky items tangled together.

Reduce the load and follow the manufacturer's capacity recommendations.

If the washing machine did not spin properly, the clothes may be unusually heavy.

Step 7: Untangle Large Laundry Items

Sheets, comforters, and blankets can twist together into a large, heavy bundle.

As the bundle rotates, it may strike the drum and create repetitive thumping.

Untangle and rearrange the laundry.

Use Bedding or Bulky Items cycles when available and recommended.

Step 8: Check Whether the Dryer Is Level

An unlevel dryer may vibrate or rock during operation.

Check whether:

  • All feet are resting firmly on the floor.
  • The appliance appears tilted.
  • The dryer rocks easily.
  • The problem began after moving it.
  • A pedestal or support is installed.

Use a level if necessary, following the owner's manual.

Do not tilt or move heavy appliances without appropriate precautions.

For stacked laundry units, mounting hardware should be evaluated by a qualified professional when technical adjustment is necessary.

Step 9: Check for External Vibration

Inspect the area surrounding the dryer.

Possible sources include:

  • Objects on top of the cabinet.
  • Items touching the side panels.
  • A nearby washing machine.
  • A pedestal drawer.
  • Vibrating cabinetry.
  • An exhaust duct touching the dryer.

Move or remove only objects that can be handled safely.

Maintain the installation clearances specified by the manufacturer.

Step 10: Inspect the Exhaust Duct

On conventional vented dryers, the exhaust duct may vibrate against the dryer or a nearby wall.

Visually check whether:

  • An accessible vent connection is vibrating.
  • The duct is touching another surface.
  • The ductwork is visibly damaged.
  • The dryer has been pushed against the vent.
  • The exhaust system appears crushed or restricted.

Do not disconnect the exhaust duct and run the dryer to test the noise.

On gas dryers, improper venting may also create a risk of combustion gases entering the home.

Step 11: Check the Lint Filter

Remove and clean the lint filter according to the manufacturer's instructions.

Look for foreign objects in the visible, accessible filter compartment.

Small items may occasionally enter the lint filter area and reach locations near the internal blower.

Do not insert your hands or tools into inaccessible areas.

If an object is trapped and cannot be removed through a manufacturer-approved procedure, arrange service.

Never operate the dryer without its required lint filter.

Step 12: Consider Worn Internal Components

If the noise persists after checking the load and accessible exterior, internal wear may be responsible.

Possible components include:

  • Drum rollers.
  • Drum bearings.
  • Idler pulley.
  • Drive belt.
  • Drum glides.
  • Blower wheel.
  • Drive motor.

Do not remove service panels to inspect these components.

A qualified technician should identify the actual cause.

Step 13: Determine Whether You Have a Heat Pump Dryer

If your dryer uses heat pump technology, some sounds may come from the compressor and condensate pump.

Consult the model-specific owner's manual to distinguish normal operating sounds from possible failures.

Do not automatically apply conventional dryer troubleshooting assumptions to a heat pump model.

Step 14: Evaluate the Results

If the noise was mild, clearly associated with a loose object or laundry load, and no safety concerns are present, the solution may be simple.

If the sound remains intense, occurs without laundry, or resembles grinding or scraping, do not keep testing the dryer.

Arrange professional service.

Squealing: Why Does My Dryer Make a High-Pitched Noise?

Squealing describes a high-pitched sound similar to a squeal or sharp whistle.

Depending on the intensity, it may also be described as squeaking or screeching.

Possible Causes

  • Worn idler pulley.
  • Worn drive belt.
  • Damaged drum rollers.
  • Drum bearing problems.
  • Compromised internal support components.
  • Misaligned moving parts.
  • Excessively heavy laundry.

When Might It Be Normal?

On some models, a brief squeak when the dryer first starts may disappear quickly.

Certain heat pump dryers may also produce a short squeaking sound when the drum starts or reverses direction.

However, this depends on the specific design.

When Does It Suggest a Problem?

Arrange service if:

  • The squealing does not stop.
  • The sound grows louder during the cycle.
  • It repeats continuously.
  • The drum struggles to turn.
  • You notice a burning rubber smell.
  • The noise occurs with a normal-sized load.

Can You Lubricate the Idler Pulley?

Do not apply WD-40, oil, or other lubricants to internal components as a general troubleshooting solution.

These products may be unsuitable, contaminate nearby surfaces, or fail to address the underlying wear.

Maintenance must follow the manufacturer's approved procedures and materials.

Persistent squealing is a reason to arrange professional diagnosis.

Thumping: Why Does My Dryer Make Repeated Banging Sounds?

Thumping describes a low-pitched, repetitive knocking or banging sound.

Some causes are relatively simple.

Tangled Laundry

Sheets and blankets may twist into a bundle that strikes the drum with each rotation.

Untangling the load may resolve the noise.

Heavy Items

Shoes or clothing with rigid accessories may create thumping sounds.

Follow the manufacturer's drying recommendations.

Unevenly Distributed Laundry

An unevenly distributed load can increase vibration.

Dividing or rearranging the load may help.

Temporarily Flattened Drum Rollers

After a dryer sits unused for an extended period, certain models may produce mild thumping during startup.

This can occur because the drum rollers have remained under pressure in the same position.

Manufacturers such as Whirlpool and LG describe situations where this sound becomes quieter after initial operation.

When Should You Call a Technician?

Arrange service if the thumping:

  • Continues throughout the cycle.
  • Becomes progressively louder.
  • Happens with a light load or no laundry.
  • Is accompanied by strong vibration.
  • Occurs together with scraping sounds.

Worn drum rollers or other support components may be responsible.

Do not continue operating a dryer that makes violent banging sounds.

Grinding: Why Does My Dryer Make a Scraping Noise?

Grinding describes a harsh friction sound, often resembling metal scraping against another surface.

This type of noise deserves particular attention.

Possible Causes

  • Worn drum bearings.
  • Damaged drum glides.
  • Misaligned internal components.
  • A metal object trapped between moving parts.
  • Problems with the drum support system.
  • Blower wheel damage.
  • Worn rotating mechanisms.

How Is Grinding Different From Simple Clicking?

A button or zipper usually creates short, separate tapping sounds.

Grinding often sounds like continuous scraping or friction between surfaces.

However, sound descriptions alone cannot identify the defective part.

What Should You Do?

  • Stop the drying cycle.
  • Wait until the drum stops completely.
  • Disconnect power before performing any inspection permitted by the manual.
  • Look only for visible, accessible objects near the drum opening.
  • Do not attempt to manipulate internal components.
  • Arrange professional diagnosis if no simple cause is apparent.

If you hear severe metallic grinding, do not restart the dryer just to reproduce or record the noise.

Continued operation may increase internal damage.

Rattling: Why Does My Dryer Sound Like Something Is Loose?

Rattling is a shaking or clattering sound often caused by loose objects.

Common Causes

  • Coins.
  • Keys.
  • Buttons.
  • Zippers.
  • Buckles.
  • Pens.
  • Hair clips.
  • Small metal objects.
  • Items placed on top of the dryer.
  • Objects touching the cabinet.
  • Vibrating exhaust ductwork.

What Should You Check First?

Start with the pockets and laundry load.

Then inspect the area around the dryer.

Can a Nearby Washing Machine Cause the Noise?

Yes.

When a washer and dryer are positioned close together, vibration from the washing machine's spin cycle can transfer to the dryer.

Maintain the spacing required by the installation instructions.

What if Rattling Continues After Rearranging the Load?

Possible causes include:

  • An object trapped in the lint filter compartment.
  • A loose venting component.
  • An internal part vibrating.
  • A blower wheel problem.
  • Mechanical wear.

Do not disassemble the dryer to locate the noise.

If rattling persists, arrange professional service.

Humming: Is a Humming Dryer Normal?

Humming is usually a steady, low-pitched sound.

Not every humming noise indicates a problem.

When Can Humming Be Normal?

Depending on the dryer, humming may come from:

  • The motor.
  • The circulation blower.
  • Air moving through the system.
  • A heat pump dryer compressor.
  • A condensate drain pump.

Samsung identifies certain blower-related humming sounds as normal operation.

LG also describes compressor and pump humming on applicable models.

When Should You Investigate?

Pay attention when the humming:

  • Suddenly becomes much louder.
  • Occurs without the drum turning.
  • Is accompanied by strong vibration.
  • Occurs with a burning smell.
  • Appears alongside poor drying performance.
  • Changes into grinding or banging.

A loud hum with a stationary drum may indicate a motor, drive system, or another component problem.

Should You Keep Trying to Start the Dryer?

No.

If the dryer produces a loud hum but does not tumble, stop repeated starting attempts.

Repeated attempts may worsen the failure or cause overheating.

Other Dryer Sounds: Clicking, Chirping, Scraping, and Rumbling

Although the five main sound categories cover many complaints, additional terms are common in troubleshooting searches.

Clicking

Clicking is a short, distinct sound.

It may come from clothing buttons or small metal objects.

On certain gas dryers, clicking associated with gas valve operation is normal.

However, clicking accompanied by heating problems should be evaluated in context.

Chirping

Chirping is a short, repetitive, high-pitched sound.

It may be associated with contact between moving components.

Persistent chirping may require technical inspection.

Scraping

Scraping describes a rubbing sound.

It may occur when an object becomes trapped near the drum.

If scraping is metallic or continuous, stop using the dryer.

Rumbling

Rumbling is a deep, rolling or roaring sound.

It may involve an uneven laundry load or a component such as the blower wheel.

Persistent rumbling without an obvious external cause deserves professional diagnosis.

Internal Dryer Components That May Cause Noise

This section explains the components to help you understand the possible causes.

It is not a guide to disassembling the dryer.

Drum Rollers

Drum rollers support or help rotate the drum on certain models.

When worn, they may produce thumping or squealing.

Idler Pulley

The idler pulley helps maintain proper drive belt tension.

Wear or resistance in the pulley may cause squealing.

Drive Belt

The drive belt transfers motion to the drum on many dryers.

Wear may cause noise and, in some cases, prevent drum rotation.

Drum Bearings

Drum bearings support rotating components in certain dryer designs.

Problems may produce squealing, friction sounds, or grinding.

Drum Glides

Drum glides are sliding support surfaces used in some dryer designs.

Wear may cause scraping.

Blower Wheel

The blower wheel helps move air through the dryer.

If it becomes loose, unbalanced, or obstructed, it may produce rumbling, rattling, or other abnormal sounds.

Drive Motor

The drive motor powers the dryer's mechanical systems.

Abnormal motor operation may be accompanied by unusual noise.

A qualified technician should confirm which component, if any, has failed.

Can the Laundry Load Cause Loud Dryer Noises?

Yes.

The laundry load affects how the drum moves during operation.

An Excessively Heavy Load

A very heavy load may place additional strain on drum support components.

Soaking-Wet Clothes

If the washing machine did not spin properly, clothes may enter the dryer much heavier than usual.

Bulky Items

Comforters, blankets, and bedding may twist into large bundles.

Shoes

Sneakers and other rigid footwear can strike the drum and cause strong vibration.

Air drying or a manufacturer-approved drying rack may be preferable.

Metal Accessories

Zippers, buckles, and buttons can create tapping or rattling sounds.

  • Follow the dryer's capacity limits.
  • Untangle large laundry items.
  • Separate excessively heavy loads.
  • Check the washing machine's spin performance.
  • Empty all pockets.
  • Fasten zippers.
  • Follow garment care labels.

Can an Unlevel Dryer Make Loud Noises?

Yes.

An unlevel or unstable dryer may vibrate during drum rotation.

Warning Signs

  • The appliance rocks or moves.
  • You hear the dryer contacting the floor.
  • The cabinet vibrates against nearby walls or furniture.
  • One or more feet do not rest firmly on the floor.
  • The noise began after installation or moving.

  • Arrange professional adjustment if necessary.

Do not move a gas dryer without appropriate precautions.

Never loosen gas connections or exhaust components to correct leveling.

For stacked appliances, do not modify the mounting brackets or stacking kit without qualified assistance.

New Dryer Making Noise: Is That Normal?

Some new dryers may produce unfamiliar sounds during their first few cycles.

In certain cases, these may be related to the initial operation of drum support components.

However, not every noise from a new appliance is normal.

When to Check the Owner's Manual

  • Mild thumping during initial cycles.
  • Sounds that disappear quickly.
  • Normal airflow noise.
  • Expected clicking.
  • Model-specific heat pump sounds.

When to Contact the Installer

  • Severe vibration from the first use.
  • An unlevel appliance.
  • Exhaust ductwork touching the cabinet.
  • Persistent metallic noise.
  • A dryer striking surrounding cabinetry.
  • Problems involving a stacked installation.

If the noise began immediately after installation, do not automatically assume internal wear.

The installation may need correction.

Heat Pump Dryer Sounds: What's Normal?

Heat pump dryers have additional components compared with many conventional dryers.

Depending on the model, these may include:

  • Compressor.
  • Fans.
  • Condensate pump.
  • Refrigerant circulation system.
  • Condenser cleaning mechanisms.

Humming

A humming sound may come from the compressor.

Gurgling

Sounds resembling moving water may occur as condensate travels through the system.

Buzzing

Some pumps and fans produce buzzing or vibration during operation.

Brief Squeaking

Certain models may produce a short squeak when the drum starts or reverses direction.

When Is a Noise Abnormal?

Potential warning signs include:

  • Loud metallic noises.
  • Persistent squealing.
  • Strong vibration.
  • A sound significantly different from normal operation.
  • Poor drying performance.
  • Error codes accompanied by unusual noise.

Follow your model's specific manufacturer guidance.

Do not open the compressor, condensate pump, or refrigerant circuit.

Electric vs. Gas Dryers: Troubleshooting Differences

Many mechanical noises can occur in both electric and gas dryers.

Rollers, belts, pulleys, and blowers are common components in many designs.

However, their heating systems differ.

Electric Dryers

Conventional electric dryers generally use an electric heating element.

Noises accompanied by electrical problems, overheating, or repeated circuit breaker trips require qualified inspection.

Gas Dryers

Gas burners and valves may produce normal operating sounds, including clicking.

However, abnormal operation, combustion problems, or a suspected gas leak must not be investigated by removing panels or handling gas components.

Gas Safety

If you smell gas:

  • Leave the building immediately.
  • Do not operate electrical switches or appliances.
  • Do not attempt to turn the dryer on or off.
  • Avoid flames and other ignition sources.
  • From a safe location, contact emergency services and the gas utility.

In the United States, call 911 for emergencies.

Do not return until the area has been declared safe.

Carbon monoxide is also a potential hazard from fuel-burning equipment with combustion or exhaust problems. It is odorless.

Possible causes include loose objects inside the drum, overloading, tangled laundry, external vibration, or worn internal components. Identify the sound before assuming a repair is needed.

What does it mean when my dryer is squealing?

A high-pitched squeal may involve the drive belt, idler pulley, drum rollers, or bearings. A very brief sound may be normal on certain models, but persistent squealing deserves professional evaluation.

Is it normal for a dryer to make thumping sounds?

Mild thumping may occur with heavy laundry, tangled bedding, or certain models after an extended period without use. Loud, continuous thumping or strong vibration should be investigated.

Can I keep using my dryer if it makes a grinding noise?

It is not recommended. Metallic grinding may indicate internal friction or a trapped object. Stop using the dryer and arrange service if the cause is not a visible object that can be removed safely.

Why is my dryer rattling?

Coins, zippers, buttons, external objects, and vibrating ducts are common causes. Check the laundry load and surrounding area first.

Is a humming sound from a dryer normal?

Sometimes. Motors, blowers, compressors, and pumps can produce humming sounds. However, a new, unusually loud hum or one accompanied by a malfunction may indicate a problem.

Can an unlevel dryer make a lot of noise?

Yes. Improper leveling can cause vibration, banging, and contact with nearby surfaces. Check the dryer's stability according to the manufacturer's instructions.

When should I call a technician about dryer noise?

Call a technician for persistent squealing, grinding, severe thumping, failure to tumble, burning smells, strong vibration, or noises that continue after simple checks.
