Check the display for 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.
NO BARS:
OK
Four bars indicates that the exhaust system is
severely restricted. Have the system checked
immediately, as performance will be poor.

If the Flow Sense LED is turned on, check the
exhaust system for restrictions and damage. Repair
or replace the exhaust system as needed.
NOTE
When the dryer is first installed, this test should
be performed to alert you to any existing
problems with the exhaust duct in your home.
However, since the test performed during normal
operation provides more accurate information on
the condition of the exhaust duct than does the
installation test, the number of bars displayed
during the two tests may not be the same.
Do not interrupt the test cycle, as this could result
in inaccurate results.
Even if no bars are displayed during the test
cycle, some restrictions may still be present in the
exhaust system. Refer to the Venting the Dryer
section of this manual for complete exhaust
system and venting requirements.
Your dryer features Flow Sense™, an innovative
sensing system that automatically detects
blockages and restrictions in the dryer ductwork.
Keeping ductwork clean of lint buildup and free
of restrictions allows clothes to dry faster and
reduces energy use.
• Confirm that house
gas shutoff and the
dryer gas shutoff are
both fully open.
