Installation Test (Exhaust Check) - LG DLEX4270 Series Service Manual

9-2 Installation Test (Exhaust 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.
• Y our dryer features FlowSense, 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.
