An obstruction inside a dryer exhaust duct is more than an inconvenience — it’s a serious fire risk. Lint, debris, bird nests, or collapsed ducting can restrict airflow, causing the dryer to overheat and increasing the chance of ignition.

Signs you may have an obstruction

• Dryer takes much longer to dry clothes

• Excessive heat in the laundry room or on the dryer exterior

• Burning smell during or after a drying cycle

• Lint accumulating around the dryer vent hood or inside the lint trap despite regular cleaning

Immediate steps to take

1. Stop using the dryer until you’ve confirmed the duct is clear.

2. Unplug the dryer and disconnect the exhaust duct at the back.

3. Inspect the duct and vent hood for visible lint, debris, nests, or crushed/flattened sections.

4. If you can remove the obstruction safely, clear the lint and reattach the duct. If not, call a professional.

5. Consider a professional dryer vent cleaning and inspection to ensure the entire run is clear and properly installed.

Why professional inspection matters Homeowners often miss obstructions hidden deep in duct runs, in rigid or flex duct collapses, or at exterior vent hoods. A trained inspector or dryer‑vent technician will check for fire hazards, proper vent termination, correct materials, and safe clearances.

Preventive tips

• Clean the lint trap before every load.

• Vacuum lint around the dryer and vent opening regularly.

• Use rigid or semi‑rigid metal ducting—not plastic or foil accordion ducts.

• Keep exterior vent hoods free of debris and ensure they close properly.

• Schedule professional vent cleaning annually (more often for heavy use).
