NOTE: See ELECTRIC SHOCK WARNING at begin-
ning of this section.
The upper light strip is held in the channel of the light
strip housing at the top of the upper wine storage com-
partment. To remove the upper light strip, you will need
to remove the top wine rack assembly first. Then,
extract the two light strip housing mounting screws.
Lower the end of the light strip housing opposite the
false wall down while pulling forward, and disconnect
the light strip electrical leads. Now, slide the light strip
out the end of the channel.
(See Figure 6-41)
NOTE: When reinstalling the light strip housing, care
must be taken to ensure that all wire leads are tucked
behind the light strip housing before re-securing it.
NOTE: Since the lower light strip housing is attached
to the control panel assembly in the models 427 and
427R, the complete control panel assembly must be
removed in order to gain access to the lower light strip.
