32 INSTALLATION
Installation Test (Duct Check)
Once you have completed the installation of the
dryer, use this test to make sure the condition of the
exhaust system is adequate for proper operation of
the dryer. This test should be performed to alert you
to any serious problems in the exhaust system of
your home.
• Your dryer features Flow Sense™, an innovative
sensing system that automatically detects
blockages and restrictions in dryer ductwork.
Keeping ductwork clean of lint buildup and free of
restrictions allows clothes to dry faster and reduces
energy use.
NOTE
The dryer should be cool before starting this test.
If the dryer was warmed up during installation, run
the AIR DRY cycle for a few minutes to reduce
the interior temperature.
To activate the installation test:
1
Remove the drying rack and literature, and
then close the door.
Do not load anything in the drum for this test, as
in may affect the accuracy of the results.

During the test cycle, monitor the Flow Sense™
display on the control panel. If no bars are
displayed, when the cycle ends, the exhaust
system is adequate. If the exhaust system is
severely restricted, the display will show four
bars. Other problems may also be shown with
error codes. Refer to the next page for error
code details and solutions.
