Most dryers have at least one primary lint trap, usually located just inside the door or on the top panel.

Some dryer vent installations also have an external lint trap, which is also known as a secondary dryer lint trap or a 4″ In-Line Dryer Lint Trap.
In order to help keep your drying in top working order, clean your lint trap after each load. You can also perform deeper cleaning of the lint trap every 6 months or as needed, in which you clean it with a nylon brush, detergent and water to remove any residue from fabric softener or stuck-on lint.

A dryer taking 2 hours to dry clothes is almost always caused by restricted airflow or a heating failure. The three biggest culprits are a clogged exhaust vent, a dirty lint screen, or an overloaded drum.
Checking for lint buildup involves inspecting both the visible airflow and the hidden pathways. Look for warning signs like clothes taking multiple cycles to dry or a burning smell. Next, perform the airflow and paper tests, and inspect the exterior exhaust vent to confirm proper venting.
