The quick answer
Stop if you smell burning.
Turn the dryer off for a burning odor, visible smoke, scorching, abnormal heat or unusual mechanical noise. Do not run another test load. For slow drying or weak airflow, clean the lint screen and arrange inspection of the exhaust path.

02 — Check today
Do the user-level checks only.
With the dryer off and cool, clean the lint screen and inspect the accessible area around it. Look behind the machine without moving it unsafely. From outdoors, observe whether the exhaust hood is blocked by debris; do not insert tools while the dryer is operating.
03 — Arrange service
Protect the full airflow path.
The U.S. Consumer Product Safety Commission warns that lint can block airflow, create excessive heat and contribute to dryer fires. It recommends cleaning the lint screen each load and periodic professional cleaning of the dryer interior and exhaust duct.
Safety basis: CPSC — Overheated Clothes Dryers Can Cause Fires.
04 — Prevent
Build a visible maintenance rhythm.
- Clean the lint screen before or after every load.
- Do not run the dryer while sleeping or away from home.
- Keep the area around the dryer clear of combustible clutter.
- Use the duct material and configuration required by the manufacturer and local code.
- Record the last professional inspection or cleaning date.

05 — FAQ
Questions people ask next.
How often should a dryer vent be cleaned?
There is no single interval for every home. Vent length, bends, dryer use, pets and materials affect buildup. Follow the manufacturer guidance and arrange cleaning sooner when warning signs appear.
Is cleaning the lint screen enough?
No. It is essential before or after each load, but lint can also collect in the exhaust path. The CPSC recommends periodic professional cleaning of the dryer interior and exhaust duct.
Can I keep using the dryer if clothes take longer?
Pause and investigate. Longer drying can signal restricted airflow, which raises heat and fire risk. Do not compensate by repeatedly extending cycles.
