Flow check (duct condition test) – LG PROTOCOL P154 User Manual

Page 24

Your 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: When the dryer 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 does the

installation test, the number of bars displayed during

the two tests may not be the same.

To activate the fl ow check (Duct condition test) :

NOTE: Dryer heating test must be performed before

proceeding. Then perform the duct condition test

Press and hold the DAMP DRY BEEP and

TEMP. CONTROL buttons at the same time.

While holding these buttons, press POWER

mode.
