Quick answer
If your dryer isn't drying clothes, first check the vent for blockages and ensure the lint filter is clean. Verify the heat setting is functioning and the load isn't too large.
Confirm the symptom
- Clothes remain damp after a full drying cycle
- Dryer runs for longer than usual without drying
- Excess moisture or musty smell in clothes
Tools and prep
- Screwdriver (flathead and/or Phillips)
- Vacuum with brush attachment
- Lint brush or comb
- Thermometer (optional)
- Work gloves
- Turn off the dryer and unplug it before starting
Step-by-step troubleshooting
- Check Lint FilterDo: Remove and clean the lint filter thoroughly.Observe: Is the filter clogged with lint?Means: A clogged filter restricts airflow and reduces drying efficiency.Next: If clogged, clean it and run a test cycle.
- Inspect Vent HoseDo: Check the vent hose from the dryer to the wall/roof for kinks or blockages.Observe: Is the hose blocked or crushed?Means: A blocked vent prevents proper airflow, causing poor drying.Next: If blocked, clear the obstruction or replace the hose.
- Clean Exterior VentDo: Remove the exterior vent cover and clean out lint or debris.Observe: Is the vent area outside clear of lint?Means: A clogged exterior vent restricts airflow and traps heat.Next: If clogged, clean it and test the dryer again.
- Test Heat SettingDo: Run a dry towel on the highest heat setting for 10 minutes.Observe: Does the towel become hot and dry?Means: If the towel remains cool, the heating element or thermostat may be faulty.Next: If no heat, check the heating element or thermostat.
- Check Dryer LoadDo: Ensure the load is not too large or too small.Observe: Is the load size appropriate for the dryer’s capacity?Means: Overloading or underloading can prevent proper drying.Next: Adjust the load size and dry again.
- Inspect Dryer DrumDo: Check for any obstructions or damage inside the drum.Observe: Are there any foreign objects or damaged parts?Means: Obstructions or damage can interfere with proper tumbling and drying.Next: Remove obstructions or consult a professional for repairs.
Common causes
| Cause | Likelihood | Difficulty | Part often needed |
|---|---|---|---|
| Clogged Lint Filter Restricts airflow, reducing drying efficiency. | Common | Easy | None |
| Blocked Vent Hose Prevents proper airflow and heat escape. | Common | Easy | Vent Hose |
| Clogged Exterior Vent Traps lint and heat, reducing airflow. | Common | Easy | Vent Cover |
| Faulty Heating Element Fails to generate heat, preventing clothes from drying. | Sometimes | Medium | Heating Element |
| Malfunctioning Thermostat Incorrectly regulates temperature, leading to no heat or overheating. | Sometimes | Medium | Thermostat |
| Overloaded or Underloaded Dryer Improper load size affects drying efficiency. | Sometimes | Easy | None |
| Damaged Drum or Obstructions Interferes with proper tumbling and airflow. | Rare | Hard | Drum Repair |
