Airflow is almost always the cause
A dryer is designed to pull room air, heat it, tumble it through wet clothes, and push moist air out through the vent. When any part of that path is restricted, cycles get longer and the appliance runs hotter.
The most common causes are lint buildup in the vent line, a blocked or damaged exterior termination, or a vent path that is too long, kinked, or built with the wrong materials.
Signs the vent is the problem
Clothes still feel damp after a full cycle. The laundry room feels warm or humid during use. There is a burning smell during the cycle. Excess lint is visible around the trap or the exterior hood.
What to check first
Clean the lint trap before every load. Confirm the exterior vent flap opens when the dryer runs. If either of those checks looks off, the vent line likely needs professional cleaning or repair.
