A clogged dryer vent may be your problem if you notice heavy clothes such as blue jeans or towels taking a long time to dry, or clothes feel hotter than usual at the end of the cycle. Follow these few safety tips.

If clothing is still damp at the end of a typical drying cycle or drying requires longer times than normal, this may be a sign that the screen or the exhaust duct is blocked. Inspect lint screen for rips. If any are found, replace immediately.
Most manufacturers specify the use of a rigid or corrugated semi-rigid metal duct, which provides maximum airflow. The flexible foil type duct can more easily trap lint and is more susceptible to kinks or crushing, which can greatly reduce the airflow. Note: WHITE VINYL HOSE is prohibited and should never be used in dryer venting.
Some dryer vents may need more frequent inspection, such as in homes with complex construction where the dryer vents exceed 6 feet from the outside, or with smaller stack dryers and dryers that are older and do not have moisture sensors or high temperature safety limit controls. This will reduce the fire risk and increase the dryer's efficiency.
Outside wall dampers should have a covering that will keep out rain, snow, and dirt. However, do not use wire screen or cloth of any kind to protect the exhaust opening. It can collect lint and clog areas of the dryer vent. In order to deter birds and small animals from nesting in vents, make sure the dryer vent system and damper are working suitably. Keep the area around the dryer clean and free from clutter. Clean behind dryer, where lint can build up. Have a qualified service person clean the interior of the dryer chassis periodically to minimize the amount of lint accumulation.
If it malfunctions, no one will be there to avert possible disaster.
