TL;DR
A dryer vent restriction is a partial or full blockage of the exhaust duct — packed lint, a crushed flex transition, a nest in the exterior hood, or simply too many elbows — that chokes airflow from the dryer to the outdoors. Symptoms are long drying times, a hot laundry room, and a machine that trips its thermal fuse; it is also a leading cause of dryer fires.
What it means
A dryer vent restriction is a partial or full blockage of the exhaust duct — packed lint, a crushed flex transition, a nest in the exterior hood, or simply too many elbows — that chokes airflow from the dryer to the outdoors. Symptoms are long drying times, a hot laundry room, and a machine that trips its thermal fuse; it is also a leading cause of dryer fires. Technicians verify it with an airflow or back-pressure reading and clear the full duct run, not just the lint screen.
