N62X/N82X Optical Control Assembly
The optical control assembly communicates with the
power board through a "foamed in" wire harness.
Drilling or puncturing the refrigerator rear panels may
cause damage to the wire harness. Controls and
related features are shown in Figure 39. The optical
control assembly with front box attached is shown in
Figure 40. The optical control assembly connected to
the wire harness is shown in Figure 41.
Front Box
Two tabs lock the front box to the optical control
assembly. A retaining screw on the hinge side retains
the front box to the divider. Shifting the refrigerator door
swing requires shifting the front box to the selected
hinge side.
