Top 5 Causes of Dryer Fires

Improper dryer vent material is one of the most common things we point out at an inspection. Vinyl or foil vent material can trap lint and is often kinked or crushed behind the dryer.    Dryer fires are most often caused by a buildup of highly combustible lint in the dryer's vent and duct system, which can be ignited by the dryer's heating element. To prevent these fires, homeowners should regularly clean the lint filter after every load, check and clean the entire vent system (including behind the dryer and the exterior vent), and use rigid metal venting instead of plastic or foil. Warning signs of a potential fire include a burning smell, clothes taking longer to dry, or clothes feeling hotter than usual. In case of a fire, leave the door closed, turn off the dryer, and call 911 immediately.    What Causes Dryer Fires?   Lint Buildup: The most significant cause, where lint accumulates in the dryer's heating element, exhaust duct, and on the back of the machine, providing fuel for a fire.    Improper Venting: Long, twisted, or restricted vent pipes create more opportunities for lint to collect.    Flammable Venting Materials: Using flimsy plastic or foil-based ductwork is a hazard because it can trap lint and melt when exposed to heat.    Overloading: Packing the dryer with too many clothes can cause it to overheat and take longer to dry, increasing the risk of lint buildup and ignition.    Electrical/Mechanical Issues: Faulty wiring or damaged machine parts can also contribute to dryer fires.
