If your clothes are coming out of the dryer wrinkled or damp, the air pressure may be set too low. You can easily adjust the air pressure on most home dryers by turning a knob or moving a lever located near the front of the machine.
To increase the air pressure, simply turn the knob or lever to the right. To decrease the air pressure, turn the knob or lever to the left. As you make adjustments, keep an eye on your clothes as they dry to see if further adjustments need to be made.
