Understanding Why Clothes Dryers Catch Fire
Clothes dryers are among the few appliances in your home that purposefully combine intense electrical or gas heat, high-speed motorized air movement, and dry, combustible textile fibers.
When airflow is unobstructed, the appliance safely expels hot moisture outdoors before temperatures reach critical ignition thresholds. But when airflow is restricted by lint accumulation, internal heat climbs rapidly until trapped lint ignites.
Daily, Weekly, and Monthly Maintenance Habits
1. Clean the Filter Screen Every Single Load: Remove lint before and after every drying cycle, without exception.
2. Wash the Screen Seasonally: Remove the screen, scrub with a soft brush, warm water, and dish soap to remove waxy softener buildup, and dry thoroughly before reinstalling.
3. Never Overload the Drum: Jamming excessive laundry into the drum chokes the circulation blower and forces the motor to overheat.

Eliminate Hazardous Vinyl and Thin Foil Transition Hoses
If the flexible hose connecting your dryer to the wall is white ribbed plastic or thin paper foil, replace it immediately. These materials are non-code-compliant, trap lint in every groove, crush easily, and burn like kindling.
Upgrade to smooth-walled rigid aluminum or semi-rigid metal tubing secured with metal clamps and foil tape.

Yes! Wax-coated fabric softener sheets leave a fine, invisible chemical film across the mesh lint filter, choking airflow even if no lint is visible. Wash your screen with warm water and soap every few months.
