Dryer Vent Fires: How Cleaning Protects Your Home

Why dryer vents catch fire

Lint is highly flammable. Every load sends more of it into your vent, where it gradually packs together and restricts airflow. With nowhere to go, hot air backs up and temperatures climb. Add a spark or an overheating heating element, and that trapped lint can ignite inside your wall or ductwork. According to fire-safety agencies, failure to clean is the number-one cause of home dryer fires.

The warning signs of danger

A dryer that's becoming a fire risk usually shows symptoms first:

• A burning smell during or after a cycle
• The dryer or laundry room getting very hot
• Clothes that are hot to the touch but still damp
• Lint building up around the outside vent or behind the dryer

If you smell burning, stop using the dryer until the vent is inspected.

A simple prevention checklist

• Clean the lint screen before every load
• Have the full vent professionally cleaned at least once a year
• Don't run the dryer while you're asleep or away from home
• Make sure the exterior vent flap opens freely and isn't blocked by nests or debris
