Check the exterior vent cap
Go outside and find where the dryer vents. Remove any debris, lint buildup, or animal nesting blocking the flap.

Inspect duct routing
Flexible foil or plastic ducts kink easily. Replace with rigid metal duct for runs longer than 4 feet. Maximum recommended run is 25 feet with fewer than two 90° turns.
