- Clothes dry unevenly, with some areas still wet
Tools and prep
- Screwdriver (flathead and/or Phillips)
- Lint brush or vacuum with brush attachment

- Work gloves
- Vent cleaning brush
- Towel or rag
- Turn off dryer power at circuit breaker or unplug
- Ensure area is well-ventilated
Step-by-step troubleshooting
- Check and Clean Lint TrapDo: Remove and clean the lint trap thoroughly.Observe: Lint buildup in the trap.Means: Blocked airflow due to lint.Next: Clean the lint trap and proceed to Step 2.
- Inspect Vent HoseDo: Check the vent hose for kinks, blockages, or lint accumulation.Observe: Kinks or lint in the hose.Means: Restricted airflow from the dryer.Next: Straighten or replace the vent hose if damaged and proceed to Step 3.
- Clean Dryer DuctDo: Use a vent cleaning brush to remove lint from the duct leading to the exterior.Observe: Lint or debris in the duct.Means: Blocked airflow preventing proper drying.Next: Clean the duct thoroughly and proceed to Step 4.
- Check Dryer SettingsDo: Verify the dryer is set to the correct temperature and cycle for the load.Observe: Incorrect settings for fabric type or load size.Means: Inefficient drying due to improper settings.Next: Adjust settings and proceed to Step 5.
- Test Dryer Vent CapDo: Ensure the vent cap outside is open and not blocked by debris or pests.Observe: Closed vent cap or blockage.Means: Airflow is restricted at the exhaust point.Next: Clear the vent cap and proceed to Step 6.
- Run Test Dryer CycleDo: Run a short drying cycle with a small load of damp clothes.Observe: Clothes dry completely within the expected time.Means: Issue resolved after cleaning and adjustments.Next: Dryer is functioning properly. No further action needed.
Common causes
| Cause | Likelihood | Difficulty | Part often needed |
|---|---|---|---|
| Clogged Lint Trap Blocked airflow reduces drying efficiency. | Common | Easy | None |
| Blocked Vent Hose Kinks or lint in the hose restrict airflow. | Common | Easy | Vent Hose |
| Dirty Dryer Duct Lint buildup in the duct prevents proper exhaust. | Common | Easy–Medium | Vent Cleaning Kit |
| Incorrect Dryer Settings Wrong temperature or cycle for fabric type. | Sometimes | Easy | None |
| Blocked Vent Cap Debris or pests prevent airflow from exiting. | Sometimes | Easy | Vent Cap |
| Overloaded Dryer Too many clothes reduce airflow and drying efficiency. | Sometimes | Easy | None |
| Faulty Dryer Heating Element Inadequate heat production leads to poor drying. | Rare | Medium | Heating Element |
| Malfunctioning Dryer Thermostat Incorrect temperature regulation affects drying. | Rare | Medium | Thermostat |
| Dryer Drum Not Spinning Properly Clothes don't tumble, leading to uneven drying. | Rare | Medium | Drum Roller or Belt |
| Moisture Sensor Malfunction Sensor fails to detect dryness, ending cycle too early. | Rare | Medium | Moisture Sensor |

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.
Can a clogged dryer vent be a fire hazard?
Yes, lint is highly flammable. A clogged vent increases the risk of dryer fires.
Why does my dryer feel hot but not dry clothes?
Heat without proper airflow means the moisture isn't being exhausted. Check vents and lint trap.
What's the best way to clean a dryer duct?
Use a vent cleaning brush or hire a professional for deep cleaning, especially if there's heavy lint buildup.
How do I know if my dryer's heating element is bad?
If the dryer doesn't produce any heat, the heating element may be faulty. Test with a multimeter or consult a technician.
