Dryer Vent Maintenance: A Simple Checklist
A clear lint screen and an unobstructed exhaust path help a dryer move warm, moist air outside. These short checks can make routine laundry care more complete.

The lint screen is easy to see, but lint can also collect in the exhaust duct and around the dryer. The U.S. Fire Administration reports that failure to clean was the leading factor contributing to clothes-dryer fire ignition in homes from 2018–2020. The CPSC recommends cleaning the lint filter before or after each use and cleaning lint from the vent pipe at least annually.
Remove lint from the screen. Keep the filter installed and follow the appliance manual for cleaning it.
Check that the outside exhaust outlet is clear and its flap can open while the dryer is running.
Clean lint from the vent pipe, following the dryer maker’s instructions or using a qualified service provider.
Longer drying times or damp clothes after a typical cycle can indicate restricted airflow; check the manual and arrange service if needed.
A quick visual check
- Turn off the dryer before inspecting the screen, area behind the appliance or reachable duct connections.
- Remove lint from the screen and look for visible tears or damage. Do not run the dryer without a properly seated lint filter.
- Keep boxes, laundry and other items that can burn away from the dryer.
- When the dryer is operating, check from outdoors that air is leaving the exhaust outlet and the flap moves freely. Do not reach into a running vent.
- Look for a crushed, kinked or damaged section of duct where visible. If access is tight or anything looks damaged, ask a qualified technician to inspect it.
Know when to call for help
Vent cleaning may involve moving a heavy appliance or disconnecting ductwork. If you cannot reach the entire exhaust path safely, the duct is damaged, airflow remains weak, or drying takes longer than usual after basic cleaning, use a qualified dryer-vent or appliance service professional. Follow your appliance maker’s instructions for approved vent materials and maintenance. CPSC’s safety alert notes that foil or plastic accordion-style ducts can trap lint more easily and can kink or crush; check the manual before changing any installed ducting.
A small recurring habit
Add the lint screen to your normal laundry routine and put a reminder on your calendar for the vent inspection and cleaning interval recommended by the manufacturer and local safety guidance.
