Dryer Takes Too Long to Dry Clothes — Fixes
If clothes take two or three cycles to dry, the dryer is not broken in the heating sense — it cannot move enough air to carry moisture away. Restricted airflow is the cause in the overwhelming majority of "takes forever" complaints.
1. Clean the Lint Screen (Really Clean It)
Clean the lint screen every load. Then deep-clean it: if you use dryer sheets, an invisible film builds up on the screen that chokes airflow. Scrub it with a brush under hot water until water passes straight through. A clogged screen alone can double drying time.
2. Clean the Full Vent Run
Lint builds up in the vent hose, the wall duct, and the exterior vent hood. This is the biggest cause of long drying. Disconnect the hose behind the dryer and clean the entire run with a vent brush kit; clear the exterior flap. Do this once a year minimum.
3. Check the Exterior Vent Flap
Go outside and confirm the vent flap opens freely when the dryer runs and is not clogged with lint or blocked by a bird nest. A stuck flap traps moist air inside the dryer.
4. Don't Overload
A drum packed too full can't tumble clothes through the airflow, so they dry slowly and unevenly. Dry medium loads, and separate heavy items like towels from light ones.

FAQ
Almost always restricted airflow — a film-clogged lint screen or a lint-packed vent run. Deep-clean the screen and clean the full vent from the dryer to the exterior hood.
Yes, it is the most common cause. A blocked vent traps the moist air the dryer needs to expel, so clothes stay damp and cycles run long.
Always unplug an appliance and shut off its water supply before servicing. This guide is informational and not a substitute for a qualified technician.
