Electrical Requirements and Components - cont'd.
AC Power Cord
The AC power cord shown in Fig. 33 is used on units without
ice maker. On all AC power cords the round side of the plug
that connects to the power board faces the left side of the
power board. The cord's grounding prong on the AC outlet
connector must be left intact and never be modifi ed or cut. The
cord's ground wire (green wire) must always be fastened to the
refrigerator cabinet metal plate.
Power Cord for Ice Maker Units
The AC power cord shown in Fig. 33 is used on NX64XIM /
NX84XIM and NXA64XIM / NXA84XIM units (IM = ice maker).
The cord has two short wire leads originating at the rear of
the power board connector plug to connect the ice maker wire
harness black and white leads. The smooth wire is the (hot)
line voltage lead; it has a male quick-connect type terminal.
The ribbed wire is the neutral lead and has a female quick-
connect type terminal. Refer to Ice Maker section for ice maker
wiring pictorials and diagrams.

12VDC Ventilation Fan

The 12VDC ventilation fan, shown in Fig. 34, enhances
ventilation in sidewall venting installations (unit installed in
RV slide out enclosures). The letter "F" in a model number is
used to identify refrigerators with a factory installed 12VDC
ventilation fan. All sidewall vented units must be equipped
with a ventilation fan to prevent combustion gases and hot
ventilation air from stagnating in the enclosure.
Ventilation fans are supplied 12VDC through power board
connections. Fan operation is automatically controlled by
a thermostatic switch mounted on the condenser fi n. The
thermostat will be on the fi rst fi n from the left (as seen
looking from the back). See Fig. 35 and 36. The switch turns
the fan on when the temperature on the fi rst condenser fi n is
approximately 130 °F. The switch turns the fan off when fi n
temperature falls to approximately 115 °F.

connections using "Y" type wire connector. The fan circuit is
protected by an in-line fuse (included in the kit). The fuse, part
of the fan kit wiring is a fast acting 1 amp,
See Fig. 36. The wiring pictorial for fi eld installed fan is shown
in Fig. 37.
