Installation Test (Duct Check)

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.
