Quick answer

Check the dryer vent for blockages, clean the lint filter and drum, and ensure the dryer is getting proper heat. If the issue persists, inspect the vent duct and exhaust system for obstructions.

Confirm the symptom

Clothes feel damp or take longer than usual to dry
Dryer runs for extended periods without drying
Excess lint buildup in the lint trap or exhaust vent
Warm or no heat coming from the dryer vent

Tools and prep

Screwdriver (flathead and/or Phillips)
Vacuum with brush attachment
Lint brush or old toothbrush
Flashlight
Work gloves
Plastic cleaning brush for vents
Turn off the dryer and unplug it from the power source before starting

Step-by-step troubleshooting

Check and Clean the Lint Filter
Do: Remove the lint filter and clean it thoroughly with a brush or rinse under water if it's washable.
Observe: Lint filter is clogged with debris.
Means: Blocked airflow from lint buildup.
Next: Clean the lint filter and let it dry completely before reinserting.
Inspect the Dryer Drum
Do: Use a lint brush or vacuum to clean the inside of the drum and the area around the lint filter.
Observe: Lint or fabric softener buildup inside the drum.
Means: Obstruction in airflow or heat distribution.
Next: Clean the drum thoroughly and repeat the drying cycle.
Check the Dryer Vent Hose
Do: Locate the vent hose at the back of the dryer and disconnect it carefully. Inspect for lint buildup or kinks.
Observe: Lint accumulation or kinks in the vent hose.
Means: Restricted airflow from the dryer to the exterior.
Next: Clean the vent hose with a vacuum or brush and reattach it securely.
Clean the Exhaust Vent
Do: Use a vent cleaning brush to clear lint from the exhaust duct leading to the exterior. Check for blockages like birds' nests or debris.
Observe: Obstruction or heavy lint buildup in the exhaust duct.
Means: Blocked airflow preventing proper venting.
Next: Remove the blockage and clean the duct thoroughly.
Test the Dryer's Heat Output
Do: Run a drying cycle with the dryer door slightly open to feel the heat coming from the vent. Use a thermometer if available.
Observe: Cool or no heat coming from the vent.
Means: Possible heating element or thermostat issue.
Next: Check the heating element and thermostat for damage or malfunction.
Inspect the Dryer's Thermostat
Do: Unplug the dryer and locate the thermostat (usually near the heating element). Test it with a multimeter for continuity.
Observe: Thermostat does not show continuity.
Means: Faulty thermostat preventing heat generation.
Next: Replace the thermostat if it's faulty.
Check the Heating Element
Do: Unplug the dryer and locate the heating element (usually at the bottom of the dryer). Visually inspect for damage or burnout.
Observe: Heating element is cracked, broken, or burned out.
Means: No heat production from the dryer.
Next: Replace the heating element with a compatible one.
Verify Dryer Level and Airflow
Do: Ensure the dryer is level and not tilted forward. Check that the vent is not too long or improperly installed.
Observe: Dryer is tilted or vent is excessively long.
Means: Poor airflow due to improper installation.
Next: Adjust the dryer's leveling feet and ensure the vent is properly installed.

Common causes

Cause	Likelihood	Difficulty	Part often needed
Clogged Lint Filter Blocked airflow reduces drying efficiency.	Common	Easy	Lint filter (if damaged)
Lint Buildup in Drum or Vent Hose Obstructs airflow and traps moisture.	Common	Easy–Medium	Vent cleaning brush or replacement vent hose
Blocked Exhaust Vent Prevents proper venting of moist air.	Common	Medium	Vent cleaning kit or professional vent cleaning
Faulty Thermostat Fails to regulate heat, causing no or insufficient heat.	Sometimes	Medium	Thermostat replacement
Burned-Out Heating Element No heat production, leading to damp clothes.	Sometimes	Medium–Hard	Heating element replacement
Improper Dryer Installation Tilt or long vent restricts airflow.	Sometimes	Easy	Adjustment or vent shortening
Overloading the Dryer Clothes don't have space to tumble and dry.	Sometimes	Easy	N/A
Moisture Sensor Issues (in some models) Faulty sensors may stop heat too early.	Rare	Hard	Sensor or control board replacement

If the dryer is old and multiple parts need replacement
If the problem persists after following all troubleshooting steps

FAQ

How often should I clean my dryer vent?

Clean the dryer vent at least once a year, or more frequently if you dry large loads often or notice reduced drying performance.

Can a clogged lint filter cause a fire?

Yes, a clogged lint filter can overheat and cause a fire. Always clean it after each use and check the vent regularly.

Why is my dryer running but not getting hot?

This is usually caused by a faulty heating element, thermostat, or a tripped thermal fuse. Check these components for damage or replacement.

Is it safe to use my dryer if it's not drying properly?

It's not recommended. A dryer that doesn't dry clothes properly can overheat, consume more energy, and pose a fire risk.

Can I clean the dryer vent myself?

Yes, you can clean the vent with a vent cleaning brush or kit. However, if the vent is long or heavily clogged, consider hiring a professional for thorough cleaning.
