Why Is My Dryer Taking So Long to Dry Clothes? 7 Common Causes and Fixes

A dryer that suddenly takes much longer than usual to dry clothes can turn one load of laundry into an all-day job.

Maybe a normal load now needs a second cycle. Towels come out damp. Clothes feel warm but still hold moisture. Or the dryer seems to run and run without finishing the job.

Long drying times do not automatically mean the dryer is broken.

The cause may be something simple, such as the selected cycle, load size, lint-screen buildup, restricted exhaust airflow, or laundry entering the dryer wetter than expected.

Other cases may involve an internal heating, airflow, moisture-sensing, control, or mechanical problem that requires professional diagnosis.

Dryers vary considerably between models. Gas and electric dryers use different heating systems, and sensor-dry cycles, vent designs, load capacities, temperatures, and maintenance procedures can all differ.

That is why the safest troubleshooting approach is to start with the things you can check without opening the dryer cabinet.

Here are 7 common reasons your dryer may be taking too long to dry clothes, what you can safely check yourself, and when it is time to call an appliance professional.

Important: Follow the owner's manual for your exact dryer. Do not remove the dryer cabinet, electrical panels, heating components, gas components, motors, blowers, thermal fuses, thermostats, sensors, control boards, or wiring for basic troubleshooting.

What to Check First When Clothes Take Too Long to Dry

Before assuming that the dryer has an internal failure, start with a few simple checks.

Check the Lint Screen

A lint screen covered with lint can interfere with normal airflow.

Remove and clean the lint screen according to your dryer manufacturer's instructions.

Make sure it is reinstalled correctly before operating the dryer.

If the screen is damaged, warped, or torn, check with the manufacturer about the correct replacement.

Check the Selected Cycle

Look at the cycle currently being used.

Dryers may include settings such as:

• Sensor Dry

• Timed Dry

• Delicates

• Heavy Duty

• Bedding

• Towels

• Air Dry

• No Heat

• Low Heat

• Normal

• Eco

• Energy Saver

The names and behavior of these cycles vary by model.

Choose the cycle recommended by your dryer manufacturer and the care labels on the laundry.

Check the Load

A load may take longer when items cannot tumble normally.

Do not use a universal rule such as filling the drum exactly halfway or three-quarters full.

Instead, follow the load-size guidance for your dryer.

Check Whether the Clothes Were Very Wet Going In

If laundry is noticeably wetter than usual when it leaves the washing machine, the dryer has more water to remove.

That can dramatically increase drying time even when the dryer itself is operating normally.

Check the Accessible Exhaust Vent

Look for obvious problems such as:

• Crushed visible ducting

• Kinked accessible ducting

• Visible lint

• An obstructed exterior termination

• A vent flap that is not behaving normally

Do not move a gas dryer or disturb a gas connection just to inspect the vent.

For detailed safe vent maintenance, see How to Clean a Dryer Vent: Step-by-Step Guide.

1. The Load Is Too Large or Unsuitable for the Selected Cycle

One of the simplest reasons laundry takes longer to dry is that the load is not tumbling and drying the way the selected cycle expects.

This does not mean every large load is automatically wrong.

Dryer capacity varies.

A load that works well in one dryer may be too bulky for another.

Follow Your Dryer's Load Guidance

Check the owner's manual for information about:

• Maximum load

• Bulky items

• Towels

• Bedding

• Mixed loads

• Delicates

Do not rely on a universal percentage of drum capacity.

Why Tumbling Matters

Clothes need room to move through the drying airflow.

If items remain packed together, moisture may stay trapped between layers of fabric.

This is especially noticeable with:

• Towels

• Sweatshirts

• Jeans

• Blankets

• Sheets

• Comforters

• Heavy cotton items

One Large Item Can Cause Problems Too

A dryer does not have to be visibly stuffed for load balance to matter.

One bulky item can sometimes:

• Ball up

• Fold around itself

• Trap damp areas

• Prevent other items from tumbling normally

Follow your dryer's instructions for bulky items.

Do Not Automatically Divide Every Load in Half

Some online advice recommends always running smaller loads.

That is unnecessary.

If your normal loads have historically dried well and suddenly take much longer, look for a change rather than assuming the dryer is overloaded.

Dryer Taking Two Cycles to Dry Clothes

If you suddenly need two cycles where one used to be enough, check:

1. Lint screen

2. Cycle selection

3. Load size

4. Clothing moisture after washing

5. Accessible dryer vent

6. Exterior vent outlet

If those checks do not reveal the cause, the dryer may need professional evaluation.

2. The Dryer Cycle or Settings Are Not Appropriate for the Load

Dryer settings can affect drying time substantially.

A cycle designed to protect delicate fabrics may use different heat, tumbling, or sensor behavior than a cycle intended for heavier laundry.

Check the Fabric Care Labels

The clothing or bedding care label should guide:

• Whether an item can be tumble dried

• Appropriate heat level

• Special drying instructions

Do not automatically use high heat because an item is thick or heavy.

High heat may damage some fabrics.

Check for Air-Only or No-Heat Settings

If the dryer is accidentally set to:

• Air Dry

• Air Fluff

• No Heat

• Another nonheated cycle

clothes may take much longer to dry.

This can easily happen if a control knob or touchscreen setting was changed.

Sensor Dry vs. Timed Dry

Some dryers offer both sensor-based and timed cycles.

Sensor systems vary significantly.

Do not assume one is always faster or better.

Use the mode recommended for the load and your dryer.

Eco or Energy-Saving Modes

Some energy-saving modes may use different heat or cycle behavior.

If drying time changed after selecting a new mode, check the owner's manual to see how that mode is designed to operate.

Do not disable safety or efficiency features just to shorten drying time.

Has a Setting Changed Accidentally?

If drying performance changed suddenly, check whether someone altered:

• Heat level

• Dryness level

• Cycle

• Energy setting

• Wrinkle setting

• Delayed start

• Sensor setting

A simple control change may explain the difference.

3. The Lint Screen Has Buildup

The lint screen captures fibers released from clothing during drying.

If it becomes heavily coated, airflow can be reduced.

Clean the Lint Screen

Remove lint according to the dryer's instructions.

The U.S. Fire Administration recommends cleaning the lint filter each time the dryer is used.

Make sure the screen is correctly reinstalled before starting the dryer.

What If the Screen Looks Clean?

Some screens may develop residue that is not obvious.

If the manufacturer provides a deeper cleaning method for the lint screen, follow it.

Do not assume that every lint screen should be:

• Soaked

• Scrubbed

• Washed with detergent

• Treated with household cleaners

Inspect for Damage

A lint screen that is:

• Torn

• Warped

• Cracked

• Loose

• Missing sections

may need replacement.

Do not patch it with:

• Tape

• Glue

• Mesh

• Fabric

Check the Accessible Lint-Screen Housing

If your manufacturer permits homeowner cleaning around the lint-screen opening, remove loose accessible lint using the approved method.

Do not:

• Unscrew dryer panels

• Reach toward the blower

• Push tools deep inside

• Remove sensors

• Remove electrical components

4. Dryer Exhaust Airflow Is Restricted

A dryer must move moisture-laden air out of the appliance.

If the exhaust path is restricted, clothes may remain damp longer.

This is one of the most important things to check when drying time increases significantly.

Look at Accessible Ducting

If the vent duct is safely visible, inspect it for:

• Crushing

• Severe kinks

• Visible lint buildup

• Disconnected sections

• Damage

Do not assume you should move the dryer to inspect everything behind it.

Gas Dryer Warning

If the dryer uses gas, do not move it if doing so could:

• Pull the gas connector

• Bend the gas line

• Loosen a fitting

• Disturb the gas supply

Do not disconnect or reconnect gas lines as part of routine drying-time troubleshooting.

Call a qualified professional if safe vent access requires moving the gas dryer.

Exterior Vent

If the dryer vent terminates at an exterior wall that you can observe safely, check for:

• Visible lint

• Leaves

• Debris

• Damaged vent hardware

• A damper that does not behave normally

Do not climb onto a roof.

If the vent terminates in an unsafe or inaccessible location, call a professional.

Do Not Use a Universal Vent-Length Rule

Dryer manufacturers provide installation requirements that may include:

• Approved vent materials

• Maximum equivalent length

• Number of bends

• Termination requirements

Follow those instructions.

Do not simply decide a vent is “too long” based on a generic internet rule.

Do Not Use Aggressive Cleaning Tools

Avoid general DIY recommendations involving:

• Leaf blowers

• Compressed air

• Improvised pressure cleaning

• Aggressive drill-powered brushes

For more detailed instructions, read How to Clean a Dryer Vent: Step-by-Step Guide.

Dryer Takes Longer After Vent Cleaning

If drying time became worse immediately after vent work, something may have changed.

Possible user-visible concerns include:

• Accessible ducting became crushed

• A connection shifted

• The dryer was pushed too close to the wall

• Exterior airflow changed

• The vent system was not completely cleared

Do not disassemble hidden ductwork or disturb gas/electrical connections.

If the vent was professionally serviced, contact the person who performed the work and explain what changed.

5. Clothes Are Entering the Dryer Wetter Than Expected

Sometimes the dryer is blamed for a problem that starts in the washing machine.

If clothes leave the washer much wetter than they normally do, the dryer simply has more moisture to remove.

Compare With Normal Washer Performance

Ask yourself:

• Are clothes heavier with water?

• Is water dripping from certain items?

• Did the washer finish its cycle normally?

• Was there an error message?

• Was the load unusually unbalanced?

• Did the washer complete the intended spin?

Check Washer Settings

Some washer cycles intentionally use different spin behavior.

For example, settings intended for:

• Delicates

• Hand-wash items

• Certain bulky fabrics

may leave more moisture in the laundry than other cycles.

Check the washer manual and garment care labels.

Do Not Assume Front-Load vs. Top-Load Is the Answer

Washing-machine designs vary greatly.

It is not accurate to say that every front-loading washer will always remove more water than every top-loading washer.

Focus on whether your washer's performance has changed.

Check for a Washer Problem Separately

If clothes repeatedly come out unusually wet, troubleshoot the washing machine rather than trying to compensate by repeatedly running the dryer.

Possible washer issues may require separate diagnosis.

Do not remove washer pumps, internal hoses, wiring, or other components as part of dryer troubleshooting.

6. Heavy or Mixed Fabrics Are Drying Unevenly

Different fabrics hold and release moisture differently.

A light synthetic shirt may dry much sooner than:

• Thick cotton towel

• Sweatshirt

• Denim

• Blanket

• Bedding

That difference is normal.

Mixed Loads

When lightweight and heavyweight fabrics are mixed together, some items may be dry while others remain damp.

Follow your dryer manufacturer's recommendations for sorting and cycles.

Towels

Towels are designed to absorb water.

That can make them take longer than lightweight clothing.

Do not automatically use the hottest setting.

Use:

• Fabric care label

• Dryer manufacturer guidance

• Appropriate cycle

Bedding

Sheets, blankets, and other large items may:

• Fold over themselves

• Ball up

• Trap damp areas

• Prevent even tumbling

Many dryers have model-specific bedding or bulky-item instructions.

Follow those instructions.

Do Not Assume “Smaller Is Always Better”

Running tiny loads unnecessarily may not improve performance.

Use the load recommendations for your dryer and the item being dried.

7. An Internal Heating, Airflow, Sensor, Control, or Other Dryer Fault May Require Professional Diagnosis

If basic checks look normal but drying times remain much longer than before, an internal appliance issue may be involved.

Possible professional-diagnosis areas include:

• Heating system

• Burner system on a gas dryer

• Internal airflow components

• Moisture-sensing system

• Temperature controls

• Motor

• Blower

• Wiring

• Control board

• Other appliance components

These are possibilities, not diagnoses.

Do Not Diagnose the Heating Element From Drying Time Alone

A dryer taking too long does not prove:

• Heating element failure

• Thermal fuse failure

• Thermostat failure

• Igniter failure

• Gas valve failure

• Sensor failure

Professional diagnosis may be needed.

Do Not Test Internal Electrical Components

Do not remove panels and use a multimeter to test:

• Heating element

• Thermal fuse

• Thermostat

• Moisture sensor wiring

• Motor

• Control board

• Switches

• Wiring

for basic homeowner troubleshooting.

Gas Dryer Internal Components

Do not inspect or manipulate:

• Burner

• Gas valve

• Igniter

• Gas tubing

• Gas supply fittings

If a gas dryer is not heating properly, use professional service.

Dryer Getting Hot but Clothes Staying Damp

When the dryer produces noticeable heat but clothing remains damp, airflow deserves attention.

Start with:

• Lint screen

• Load

• Cycle

• Accessible exhaust duct

• Exterior outlet

Do not assume that heat proves the heating system is functioning perfectly.

Dryer Running but Producing Little or No Heat

First check:

• Cycle

• Heat setting

• Air-only mode

If the controls are appropriate and the dryer still produces little or no heat, stop before opening the cabinet.

An internal heating-system issue may need professional diagnosis.

Dryer Running Constantly Without Drying

If the dryer seems to run for a very long time:

• Check whether it is using a sensor cycle.

• Check the load.

• Check the lint screen.

• Check accessible vent airflow.

• Check whether clothes were excessively wet after washing.

Do not diagnose a sensor from cycle length alone.

Sensor behavior varies by dryer.

Burning or Hot-Lint Smells

A genuine burning odor is a warning sign.

Stop using the dryer.

Do not simply keep running cycles to see whether the smell disappears.

Possible concerns may include:

• Lint

• Overheating

• Electrical problems

• Internal dryer problems

• Another heat-related fault

Do not try to identify the failed internal component yourself.

Smoke, Sparks, or Scorching

If you notice:

• Smoke

• Sparks

• Visible scorching

• Electrical burning smell

• Burning-plastic odor

• Melted plug

• Melted outlet

• Severe overheating

stop using the dryer and seek appropriate professional or emergency assistance.

Suspected Gas Odor

If you smell gas around a gas dryer:

• Stop dryer troubleshooting.

• Avoid flames and smoking.

• Do not manipulate the gas line.

• Follow your gas utility or emergency guidance.

Dryer Taking Longer After Being Moved

If drying performance changed after moving the dryer, the vent may deserve attention.

Look only at safe, visible areas.

A vent may have become:

• Crushed

• Kinked

• Shifted

Do not move the dryer repeatedly, particularly if it is gas-powered.

How Long Should a Dryer Take?

There is no universal drying time.

Drying time depends on:

• Dryer model

• Load size

• Fabric type

• Cycle

• Washer spin performance

• Vent design

• Room conditions

• Moisture level

Compare the dryer with its own previous normal performance rather than a generic number from another appliance.

A sudden change is often more meaningful than whether a cycle takes a particular number of minutes.

What If Drying Has Always Been Slow?

If the dryer has always taken a long time, the issue may involve:

• Vent installation

• Dryer capacity

• Load habits

• Washer performance

• Cycle selection

• Appliance design

Check the manufacturer's instructions and consider having the vent system evaluated.

What If Drying Suddenly Became Slow?

A sudden change makes these checks especially useful:

1. Lint screen

2. Cycle

3. Load

4. Washer moisture extraction

5. Accessible exhaust vent

6. Exterior vent

7. Display or error messages

If none explains the change, professional service may be appropriate.

Common Dryer Troubleshooting Mistakes

Using a Universal Drum-Fill Rule

Dryer capacities vary.

Follow your model's instructions.

Turning the Heat Higher Automatically

High heat is not appropriate for every fabric.

Use the garment care label and dryer instructions.

Running Repeated Cycles Without Checking the Vent

A sudden drying-time increase deserves investigation.

Assuming Heat Means the Dryer Is Fine

A dryer can produce heat and still have another problem.

Assuming No Heat Means the Heating Element Is Bad

Many different systems can affect heating.

Professional diagnosis may be needed.

Removing the Dryer Cabinet

Basic drying-time troubleshooting does not require internal access.

Using a Multimeter on Dryer Components

Leave internal electrical diagnosis to qualified service.

Moving a Gas Dryer

Do not disturb its gas connection.

Cleaning the Vent With a Leaf Blower

Use appropriate vent-cleaning methods.

Diagnosing a Sensor From Cycle Length

Sensor behavior varies.

Diagnosing the Motor From Noise

A noise alone does not identify a failed motor or other internal component.

Repeatedly Resetting a Breaker

If the dryer repeatedly trips a breaker, stop using it and arrange appropriate professional evaluation.

When to Call an Appliance Professional

Contact your dryer manufacturer or a qualified appliance technician if:

• Drying time remains much longer after basic checks.

• The dryer produces little or no heat with appropriate settings.

• The dryer severely overheats.

• A burning or electrical smell appears.

• Smoke or sparks occur.

• A breaker repeatedly trips.

• Dryer controls repeatedly show error codes.

• An internal component may require diagnosis.

• The dryer produces persistent abnormal noises along with poor performance.

• A gas dryer has a heating problem.

• Moving the dryer would disturb a gas connection.

• The vent is inaccessible or cannot be safely cleared.

Frequently Asked Questions

Why is my dryer taking so long to dry clothes?

Possible causes include load size, cycle selection, lint-screen buildup, restricted exhaust airflow, laundry entering the dryer excessively wet, mixed heavy fabrics, or an internal dryer problem.

Why does my dryer take two cycles?

Check the lint screen, cycle, load, washer spin performance, and accessible dryer vent.

If it previously dried the same loads in one cycle and now consistently requires two, something has changed.

Why does my dryer get hot but clothes stay damp?

Restricted airflow is one possibility.

Check the lint screen and accessible vent system.

If those are normal, professional diagnosis may be needed.

Why is my dryer running but not heating?

First check whether an air-only or no-heat cycle is selected.

If the settings are correct, internal heating-system diagnosis should be left to a professional.

Can a clogged dryer vent make clothes take longer to dry?

Yes. Restricted exhaust airflow can interfere with moisture removal and contribute to longer drying times.

For detailed instructions, see How to Clean a Dryer Vent: Step-by-Step Guide.

How often should I clean the lint screen?

The U.S. Fire Administration recommends cleaning the lint filter each time the dryer is used.

Follow your dryer manufacturer's instructions.

How often should I clean the dryer vent?

Follow your dryer and vent maintenance instructions.

U.S. Fire Administration guidance recommends annual dryer vent ductwork cleaning, with earlier attention when drying performance changes or visible lint buildup appears.

Should I use high heat to dry towels faster?

Not automatically.

Follow the towel care label and your dryer manufacturer's recommended cycle.

Why do towels take longer to dry?

Towels absorb and retain more moisture than many lighter fabrics.

Use the appropriate load and cycle instructions for your dryer.

Why does bedding stay damp in the middle?

Large items can fold or ball up and trap damp sections.

Follow the dryer's bedding or bulky-item instructions.

Could my washing machine be causing long dryer times?

Yes.

If laundry comes out of the washer much wetter than it normally does, the dryer has more water to remove.

Does a dryer taking longer mean the heating element is failing?

Not necessarily.

Drying time alone cannot diagnose the heating element.

Should I test the thermal fuse?

Not for basic troubleshooting.

Thermal fuses and other internal electrical components should be diagnosed by qualified service.

Can dryer sheets make drying slower?

Do not assume dryer sheets are responsible simply because drying time increased.

Follow the dryer and dryer-sheet manufacturer's instructions.

If your lint screen has visible residue, clean it according to your dryer manufacturer's procedure.

Why is my dryer running forever on sensor dry?

Check the load, settings, lint screen, vent, and laundry moisture.

If the problem continues, the sensor system or another internal component may require professional diagnosis.

Is a burning smell normal if the vent is dirty?

No.

Stop using the dryer when you notice a true burning odor and determine the cause before operating it again.

Why did my dryer start taking longer after I cleaned the vent?

Check accessible ducting for crushing, kinks, loose connections, or another visible change.

If a professional cleaned the system, contact them if performance became worse immediately afterward.

How long is too long for a dryer cycle?

There is no single number that applies to every dryer and load.

A significant change from your dryer's previous normal performance is more useful than comparing it with another machine.

When should I replace my dryer?

Long drying time by itself does not mean the dryer needs replacement.

Have the problem properly diagnosed before deciding whether repair or replacement makes sense.

Final Thoughts

If your dryer is taking too long to dry clothes, start with these 7 common causes:

1. The load is too large or unsuitable for the selected cycle

2. The dryer settings are not appropriate for the load

3. The lint screen has buildup

4. Dryer exhaust airflow is restricted

5. Clothes are entering the dryer wetter than expected

6. Heavy or mixed fabrics are drying unevenly

7. An internal heating, airflow, sensor, control, or other dryer fault

Start with safe, visible checks:

lint screen, load, settings, clothing moisture, accessible vent ducting, and the exterior vent outlet.

Do not open the dryer cabinet, test internal electrical components, manipulate gas parts, or diagnose a heating element, thermal fuse, motor, sensor, or control board from symptoms alone.

And if the dryer develops a burning smell, smoke, sparks, severe overheating, repeated breaker trips, or suspected gas odor, stop using it and seek appropriate professional help.
