Check the Duct Condition
TM
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 appliance 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 the installation test, the results during the
two tests may not be the same.
• Do not interrupt the test cycle, as this could
result in inaccurate results.
• Even if the LED doesn't light up 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.
