Check the duct condition
If the test displays FLOW SENSE, check the exhaust system for
restrictions and damage. Repair or replace the exhaust system as
needed.
NOTE
When the dryer is first insralled, 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, FLOW SENSE
displayed during the two tests may not be the same.
Do not interrupt the test cycle, as this could result in the wrong
results.
Even if FLOW SENSE is not 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.
