Dryer fires cause thousands of home fires every year in the U.S., and restricted airflow — from a clogged lint screen or a blocked exhaust vent — is consistently the leading cause.
Why Lint Buildup Is So Dangerous
Lint is highly flammable, and a dryer’s heating element operates at high temperatures right next to it. Restricted airflow raises internal temperature well beyond normal operating levels.
Warning Signs You Shouldn’t Ignore
Clothes taking multiple cycles to dry, the dryer or vent area feeling unusually hot, or a burning smell during operation are all signals that airflow is restricted enough to warrant immediate attention.
What to Do If You Smell Burning
Stop the dryer immediately, unplug it or switch it off at the breaker, and don’t run it again until inspected.
Prevention Is Simple
Clean the lint screen every load and schedule a full vent cleaning annually. Visit our dryer repair page if you’re overdue for an inspection.
