This problem is typically brought on by kinked vent tubing, a blockage in the vent, or too much venting material between the location of the dryer and the vent outside the home. If the venting material is excessively lengthy, it should be cut as close to the desired length as feasible. If the venting material appears sufficient in size, there may be a blockage in the vent or an excessively lengthy line from the dryer vent to the outside. Turning on the dryer without any clothes is an easy way to check the vent airflow. The airflow rate must match the amount of air venting from the dryer without using any.
