Ac Power Cord; Power Cord For Ice Maker Units; 12 Vdc Ventilation Fan - Norcold N61X Service Manual

AC Power Cord

The AC power cord shown in Figure 23(a) 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 modified 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 Figure 23(b) is used on
N64X IM and N84X IM 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 short ribbed
wire is the line voltage lead, it has a female quick-
connect type terminal. The smooth wire is the neutral
lead, has a male quick-connect type terminal. Refer to
pages 71 and 72 for ice maker wiring pictorials and
diagrams.
All N643IM and N843IM units are equipped with an
independent AC power cord (white in color) to supply
120 Vac to the ice maker only.

12 Vdc Ventilation Fan

The 12 Vdc ventilation fan, shown in Figure 24,
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 12 Vdc 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 12 Vdc through power
board connections. Fan operation is automatically
controlled by a thermostatic switch mounted on the
first condenser fin. See Figure 25. The switch turns the
fan on when the temperature on the first condenser fin
is approximately 130 °F. The switch turns the fan off
when fin temperature falls to approximately 115 °F.
NORCOLD fan kit is wired to the power board 12 Vdc
®
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 x 1 " AGC type. See Figure 26. The wiring
