Multi-Duct Online Training Manual for LG Products - MultiDuct      
27_1 The multi-duct in the back of the refrigerator can include air ducts, vents, dampers, LEDs for the crisper drawers, and thermistors.

27_2 To remove the multi-duct, pry the covers off both ends of the bracket channel. Then remove the two Phillips screws (but not the silver one attaching the rack to the duct.)

27_3 Pull the multi-duct away from the refrigerator back at the top and lift it out of the opening at the bottom.

This opening allows the cold air from the freezer to come into the refrigerator.

Unplug the connector which powers the LEDs, the damper, and the thermistor to remove the multi-duct.

The bottom of the duct is inserted into the opening at the base of the refrigerator to ensure proper air flow and cold air distribution.
