Artlessly stated, a shut dryer vent is caused by the build-up of lint in the dehydrating ventilation system. There are many causes a clothes dryer vent may be clogged. First, the complex construction of new houses built today tends to have dryers located away from an out wall. This means dryers tend to be vented longer ranges make more curvatures in the vent through the house. The extra length creates more places for lint to gather or for animals and birds to hide. Secondly, dryer vents are often made from elastic plastic or foil duct, which may be readily kinked or crushed where they egress the dryer and enter the wall or floor. |
