Installation Test (Duct Check) - LG W3S1 Series Service Manual

6-5. 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.
