LMX28983ST Page 28 FOUR DOOR REFRIGERATOR
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.
LAMP (LED ARRAY, REFRIGERATOR)
The light in the refrigerator is provided by
an LED array which is switched on when
either refrigerator door is opened.
Remove the four screws along the front
edge of the cover and release the two snap
fittings on the back to take the array out of
the ceiling of the refrigerator compartment.
The individual parts for the array are
available, allowing repairs, including
replacement of the LEDs themselves, rather
than replacing the array as an assembly.
The freezer LED array is smaller but works
in a similar manner.
DAMPER
The stepping motors for the dampers are
wired with four connections; the blue and
red control the A coil, and white and yellow
control the B coil.
