Step-by-step fix
1. Clean the lint screen every load
This is the fastest preventive habit. Also wash the screen if residue from dryer sheets blocks airflow.
2. Check the outside vent
When the dryer runs, air should move freely from the exterior vent. Weak airflow can signal a blockage.
3. Look behind the dryer
Crushed, kinked or disconnected ducts reduce airflow and can collect lint.
4. Do not ignore burning smells
Stop the dryer. Let it cool. If the smell continues or the dryer overheats, call a qualified technician.
5. Schedule deeper cleaning
A home with frequent laundry may need more frequent vent cleaning than a light-use household.
Important warning
Dryer fire risk is serious. Stop using the dryer if you smell burning, see smoke, or the dryer overheats.
Prevention routine
- Fix the source before adding fragrance, sprays or candles.
- Keep wet areas dry and ventilated.
- Clean tools and filters, not just visible surfaces.
- Use the smallest effective amount of cleaner to prevent residue buildup.
- Recheck the same area 24 hours later; recurring odor means the source is still active.
FAQ
How do I know if my dryer vent is clogged?
Long drying times, hot clothes, weak exterior airflow and burning smells are common warning signs.
Is lint really a fire risk?
Yes. Lint is combustible and restricted airflow can cause overheating.
Can I clean the vent myself?
You can clean the lint screen and visible vent areas, but long ducts or repeated warnings may need a professional.
