Airflow problems:
Airflow problems are usually caused by restrictions,
leaks or short unrestricted vents resulting in longer dry-
ing times, hotter dryer surfaces and in extreme cases
causing the thermal limiter to open on electric dryers.
Restrictions:
Restrictions can occur any place in the airflow system,
but the most common are:
1. Installing the dryer in a small inclosed area; such
as a closet without a louvered door that reduces
the intake air.
2. Fan problems caused by either a slow running
motor, a broken or deformed fan blade or a
deformed fan housing.
3. A lint restriction in the lint screen area. Operator
may not be cleaning the lint screen before using.
4. A restriction in the exhaust system in the house
caused by the design of the vent, such as; the
diameter of the vent pipe being too small, too long,
too many right angles, or a collapsed or lint restricted
vent pipe.
Note: Problems caused by the vent pipe in the house
are not cover under the product warranty.
Air leaks:
Two types of air leaks may occur:
1. Air being drawn in around the door opening, between
the drum and the front panel, or around the foam seal
between the front duct and the blower housing, re-
places some of the air being drawn through the drum
and lowers the efficiency of the dryer.
Note: An air leak that occurs around the door
opening or between the drum and the front
panel usually will cause lint to build up on
the inner panel of the door.
2. Air being pushed out around the blower housing
or vent pipe inside the dryer, allows some of the
moisture that has been removed from the clothes
to be recirculated.
Short unrestricted vents:
The venting system in the dryer is designed to operate
under some back pressure. This back pressure is
needed to slow the airflow and allow the air to be heated
before it passes through the clothes.
Note:
With short direct vent runs; such as you have
when the dryer is installed against an outside
wall, use a 2 1/2” vent cap rather than a 4”
vent cap.
