A restricted vent Most common
Hot air carries the water out of the clothes, and it has to leave through the duct. Lint builds up along the run, at every bend and at the outside hood, and a crushed foil duct behind the machine chokes it further. The dryer still heats, so clothes come out hot and damp.
Colby checks the airflow from the drum to the hood and shows you where it’s blocked.
