REFRIGERATOR CONTROLS AND OPERATING INSTRUCTIONS

A 12-volt DC supply is required to maintain the refrigerator's operating control functions. The
refrigerator receives its DC power from the vehicle's 12-volt system; either an auxiliary battery, a
converter or the engine battery. The 12-volt DC system not only supplies power to the refrigerator,
but to other DC components in the vehicle.
NORCOLD
The control panel, conveniently located between the freezer compartment and the fresh food
compartment, contains the functionality needed by the owner. The window (A) of the control panel
is equipped with a light which illuminates the LCD display. This light turns on when any button is
pressed, and remains on for 10 seconds after the button is released.
The On/Off button (E) turns the refrigerator "On" or "Off". When the refrigerator is "Off", pressing
this button will turn the refrigerator "On" and set the mode to "AUTO". When the refrigerator is
"On", pressing this button for 2 seconds will turn the refrigerator "Off".
Pressing and holding the "MODE" button (C) allows that user to cycle through the four mode
choices; one "AUTO" and three manual modes (AC, LP GAS, OR BATT). The refrigerator will not
switch to the new operating mode until the "MODE" button is released.
The "TEMP SET" (thermostat) button (D) controls the refrigerator and freezer temperature during
both gas and electric operation, eliminating the need to reset each time a different energy source is
selected. Press and hold the "TEMP SET" button to select the desired temperature setting. The
temperature settings are shown in the form of a thermometer (B) in the display window, with the
shortest thermometer reading indicating the coldest setting.
AUTO MODE
When the "AUTO" mode is selected, the operating control automatically selects the energy source
using the following priority scheme:
• When 120-volts AC is available to the refrigerator, "AUTO AC" will be visible in the display
panel, indicating the refrigerator is operating on AC electric.
• If 120-volts AC is not available, the refrigerator will switch to the gas operation, and "AUTO
LP GAS" will be visible in the display panel.
• When neither 120-volts AC nor LP gas are available, the refrigerator will switch to DC
electric (3-Way models only) and "AUTO BATT" will be visible in the display panel. DC
electric operation is not as efficient as LP gas or AC electric operation, and should therefore
