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 num-
ber 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 sens-
ing 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.
