Common Causes of Extended Drying Times
If your dryer used to finish a load in 40 minutes and now needs 80, something has changed. Here are the most common causes and what actually fixes them.
Restricted Vent Airflow
The number one cause of longer drying times is restricted vent airflow from lint buildup. When moist air can't escape efficiently, clothes stay damp longer. This is a gradual problem — you may not notice the slow decline until it's severe.
Professional vent cleaning restores full airflow and typically returns drying times to normal immediately.
Blocked Exterior Hood
The exterior vent hood can become blocked by lint accumulation, bird nesting, or a stuck damper flap. Go outside while the dryer runs and check if the flap opens freely. If not, there's a blockage at the termination.
Crushed Transition Duct
The flexible duct behind the dryer is easily crushed when the machine is pushed too close to the wall. Even partial crushing significantly restricts airflow. Pull the dryer out and check for kinks or flattening.
Overloading the Dryer
An overloaded dryer can't tumble clothes properly, trapping moisture. Dry smaller loads and ensure clothes have room to move.
When to Call a Professional
If you've checked the obvious causes and drying times are still long, your vent system likely needs professional cleaning. Deep blockages in wall or attic runs can't be cleared without proper equipment.
