How to Fix a Dryer That Takes Too Long to Dry

A dryer that takes too long usually has a clogged lint filter, blocked exhaust vent, or overloaded drum that restricts airflow and heat circulation.

1. Clear the First Blockage. Remove the lint screen and clean off all visible lint. Wash it with warm soapy water to remove fabric softener buildup that blocks airflow. A clogged filter forces your dryer to work twice as hard and cuts drying efficiency in half. Let it dry completely before reinstalling.
2. Unblock the Exit Route. Go outside and locate your dryer vent. Remove any debris, lint, or bird nests blocking the opening. The vent flap should move freely when the dryer runs. A blocked exterior vent creates back-pressure that prevents hot, moist air from escaping, leaving clothes damp.
3. Free the Hidden Lint Trap. Pull the dryer away from the wall and disconnect the flexible duct. Check for kinks, crushing, or lint buildup inside the duct. Vacuum out any accumulated lint and ensure the duct has a smooth, unrestricted path to the outside. Reconnect securely with clamps.
4. Give Clothes Room to Breathe. Overloading prevents clothes from tumbling properly and blocks airflow. Remove half the load if it fills more than two-thirds of the drum. Shake out tangled items and redistribute heavy pieces like jeans and towels. Clothes need space to move and allow hot air to circulate.
5. Match Heat to Fabric. Match heat settings to fabric types. Heavy cottons need high heat, while delicates require low heat. Using too low a setting extends drying time unnecessarily. Check that your dryer is actually producing heat by feeling the exhaust air outside during a cycle.
6. Reset the Smart Sensors. Locate the metal sensor strips inside the drum, usually on the front wall. Wipe them clean with a damp cloth to remove fabric softener residue. Dirty sensors give false readings, making the dryer think clothes are dry when they are still damp.
