This appliance is designed for storage of foods, storage of frozen foods, and making ice.  
Storage Volume  
Models - 962, 963 = 6.3 cu. ft.  
Models - 982, 983 = 7.5 cu. ft.  
Leveling  
Warning: Operating refrigerator outside of the cooling system specification of 3 degrees off level  
side-to-side and 6 degrees off level front-to-back can cause irreparable damage to cooling system  
and can create a risk for personal injury and property damage. Level vehicle before operating  
refrigerator.  
Comfortable vehicle leveling is well within the refrigerator’s operating requirements of 3 degrees off level side-to-side and  
6 degrees off level front-to-back (looking at the front of the refrigerator). Continued operation outside of these limits can  
result in irreparable damage to the cooling system.  
Freezer Compartment  
The freezer compartment is not intended for quick freezing of foods; it retains food in a frozen state. The recessed bottom  
helps to prevent the escape of cold air when the freezer door is opened. The freezer shelf can be adjusted or removed to meet  
your storage needs.  
Fresh Food Compartment  
The fresh food compartment stores and cools food.  
For best cooling performance, air must be free to circulate within the fresh food compartment. Do not cover the shelves with  
paper, plastic, etc.  
To reduce frost formation on the cooling fins, cover liquids and moist foods, do not place hot foods in the compartment, and  
do not leave the door open longer than needed.  
Allow the refrigerator to cool for 8 hours before loading foods. Loading a warm refrigerator with warm food increases the  
cool down period.  
Defrosting and Cleaning the Refrigerator Interior  
Your refrigerator is not frost free and will require periodic defrosting. To defrost, turn the refrigerator off. Empty the freezer  
and the fresh food compartments. Placing a pan of hot water in the freezer will reduce the defrosting time. Leave the drip tray  
under the cooling fins. After frost has melted, empty the drip tray and clean the refrigerator.  
Add a small quantity of mild dish detergent to lukewarm water and wash the interior of the refrigerator. Do not use abrasive  
cleansers; they can damage the interior surfaces of the refrigerator. Rinsing both compartments in a solution of baking  
soda and water (one table spoon of baking soda to one quart of water) will freshen the interiors and neutralize odors. Wipe  
the interior with a soft dry cloth to prevent water spots. Clean the door gaskets in the same manner as the refrigerator interior.  
This will help to prolong the life of the gaskets.  
Crispers  
The crispers, located in the bottom of the fresh food compartment, provide storage to preserve fruit and vegetable freshness.  
Wrap vegetables with strong odors so that their odor will not be transmitted to other foods. Always insure the crispers are  
pushed in all the way. Important! The crispers are not dishwasher safe.  
Moisture Reduction Heater  
Your refrigerator is equipped with a heater that prevents moisture from forming on the center divider between the freezer  
and fresh food compartment doors. This heater is activated and deactivated when the refrigerator is turned "On" and "Off".

Caution: Do not replace with a bulb of higher wattage.  
Higher wattage bulbs can damage the interior surface of  
the fresh food compartment.  
Interior Light  
The interior light is located at the top of the  
fresh food compartment. The light will turn on  
whenthefreshfoodcompartmentdoorisopened  
and off when the door is closed. Power to the  
light is activated when the refrigerator is turned  
on and deactivated when the refrigerator is  
turned off.

Door Handle  
Storage Latch  
The refrigerator door handles incorporate a  
latch which insures complete closure of the  
doors.  
The handle is equipped with a storage latch  
which enables the doors to be left partially  
open to prevent build-up of odor during ex-  
tended refrigerator shut-down periods.  
Do not use storage latch as a travel latch. Using  
storage latch as a travel latch allows doors to be  
partially open.  
Strike Plate

Checking Door Seals  
To insure cooling efficiency and to prevent  
frost formation, the door gaskets must seal  
completely.  
Pull paper away  
from refrigerator  
To check for proper door seal, lay a strip of  
paper between the gasket and the refrigera-  
tor. Close the door and withdraw the paper.  
A frictional drag should be noticed. Repeat  
all around the door. If the paper does not  
have a noticeable drag, the gasket is not  
sealing. Contact your dealer or a Norcold  
service center for corrective procedures.

fresh food compartments enable you to re-  
move the shelves for cleaning and to arrange  
the shelves to fit your needs. To move the shelf  
in the freezer, pull the shelf forward, select the  
new location, and slide the shelf into place.  
Retainer  
Strips  
To move the shelves in the fresh food com-  
partment; using a Phillips screwdriver, re-  
move the three screws from each retainer.  
Lift and pull the retaining strips away from  
the refrigerator. Pull the shelves forward to  
remove, select the new location, then slide  
the shelf into place. Reinstall the retainer  
strips by reversing the above procedure.  
To prevent child entrapment, Insure the

If the lower door remains open and the interior light remains on for more than two minutes, the light turns off, a warning  
beeper sounds, a bell flashes, and code A3 appears in the center display panel. Refrigerator operation will not be  
interrupted; this alarm is intended to alert you to the fact that the door is ajar. Closing the door will turn off the alarm.  
Refrigerator Controls and Operating Instructions  
Warning: Improper refrigerant flow or cooling system blockage can cause severe personal injury,  
substantial property damage, or irreparable damage to the cooling system. Do not leave refrigerator  
unattended for more than one (1) hour after initial refrigerator start-up. If no cooling is observed in  
the freezer compartment within one (1) hour of initial start-p, turn refrigerator OFF and contact your  
dealer or an authorized Norcold Service Center for corrective action.  
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 engine battery. The 12 VDC system not only supplies power to  
the refrigerator, but to other DC components in the vehicle.

Control Panel - Figure 9  
The control panel, positioned between the freezer compartment and the fresh food compartment, conveniently locates all of  
the functionality needed by the owner. The window (B) 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 refrigerator "On"or"Off". When refrigeratoris "Off", pressing this button will turn refrigerator  
"On" and set the mode to "AUTO". When refrigerator is "On", pressing this button for 2 seconds will turn refrigerator "Off".  
8
 
Pressing and holding "MODE" button (C) allows the user to cycle through 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 "MODE" button is released.  
The "TEMP SET" (thermostat) button (D) controls 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 "TEMP SET" button  
to select the desired temperature setting. The temperature settings are shown in the form of a thermometer (A) in the display  
window, with the shortest thermometer reading indicating the coldest setting.  
Auto Mode  
When "AUTO" mode is selected, the operating control automatically selects the energy source using the following priority  
scheme:  
When 120 volts AC is available to 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 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 be used only to maintain temperatures when other modes are  
unavailable (for example; while in transit).  
During operation in "AUTO" mode, when a higher priority energy source becomes available, the operating controls will  
cease using the current energy source and will switch to the higher priority energy source. For example, if AC electric becomes  
available while the refrigerator is operating in the "AUTO LP GAS" mode, the refrigerator will switch to "AUTO AC "  
operation.  
If an operating mode is not functional, a diagnostic code will appear and the refrigerator will attempt to operate in a lower energy  
priority source. If a lower energy priority source is not available, an alarm will sound and the refrigerator will cease operation. Refer  
to "Diagnostic Codes and Their Meaning" for corrective actions.  
Manual Mode  
To operate in "MANUAL" mode, press and hold "MODE" button until "AUTO" disappears and the desired operating mode  
is displayed. If the energy source is interrupted while operating in the "MANUAL" mode, a diagnostic code will appear, an  
alarm will sound, and the refrigerator will cease operation. Refer to the "Diagnostic Codes and Their Meaning" on page 10  
for corrective actions.  
"AUTO" and "MANUAL" Modes - Gas Operation Only  
If the gas does not ignite within 30 seconds, which may occur on initial start-up, the refrigerator’s gas valve will automatically  
close and the operating controls will select an alternate energy source ( "AUTO" Mode) or, "MANUAL" mode, will revert  
to a stand-by mode in which an alarm will sound and code A1 will be displayed in the center window. The alarm and code  
will remain on until the operating controls are turned "OFF" and then "ON" again. If the gas does not ignite after several  
attempts, check the input gas supply, or consult with your dealer or a Norcold authorized service center. A different mode of  
operation may be selected by pressing and holding the "MODE" button. The refrigerator will not switch to the new operating  
mode until the "MODE" button is released.  
Backup Operating System ("BOS")  
Your refrigerator features a Back-Up Operating System which provides a means for the refrigerator to cool in the event of  
a failure within the refrigerator’s operating controls. In the event this failure occurs, the refrigerator will display Diagnostic  
Code C5 and will switch automatically to the "BOS" mode. This mode provides refrigeration until the refrigerator is serviced.  
The fresh food and freezer compartment temperatures should be monitored to prevent over-freezing or thawing of refrigerator  
contents when operating in the "BOS" mode. If the refrigerator temperature is too cold, adjust the thermostat up (warmer) in  
one bar increments. If the refrigerator temperature is too warm, adjust the thermostat down (colder) in one bar increments.  
Allow the refrigerator to operate at the new setting for one hour before rechecking the freezer and fresh food compartment  
temperatures (frequent door opening prevents the temperatures from stabilizing). While the refrigerator can operate in this  
mode, Norcold recommends that you seek service as soon as practical to restore normal operation.

Diagnostic Codes  
The refrigerator’s operating controls are equipped  
with a diagnostic system which alerts the user to  
a problem in any mode of operation. When a prob-  
lem occurs within a given mode, the operating con-  
trols willrevertto astand-by mode in which an alarm  
will sound and a diagnostic code will be displayed in  
thecentercontrolwindow.The alarm will sound until  
an alternate operating mode is selected. The diag-  
nostic code will continue to be displayed until the  
controls are turned "OFF" and then back"ON".

Refrigerator Failure  
Failure of refrigeration does not necessarily indicate that the cooling system is defective. Other factors governing its  
operation must be checked.  
If a diagnostic code appears, refer to "Diagnostic Codes and Their Meanings" on page 10. If the refrigerator is operating on  
gas and a loss of cooling is noticed, switch the refrigerator to the AC mode of operation (see Start-Up Instructions on pages  
8 and 9). If the refrigerator has been operating on electric, switch to gas operation. After the refrigerator has been switched  
from one power source to the other allow several hours to assure the refrigerator is cycling properly. This will determine if a  
component failure in the electric or gas controls is causing the cooling fault. If no cooling is evident after eight hours (or  
overnight), the cause of failure may be the cooling unit. To determine the actual cause for failure, contact your dealer or a  
Norcold service center.  
Maintenance Requirements  
Important Notice:  
Read and understand this notice before removing this refrigerator, re-installing this refrigerator, or performing any  
maintenance on this refrigerator. Norcold will not accept responsibility for installation, adjustment, alteration, service,  
or maintenance performed by anyone other than a qualified dealer or Norcold service center. Costs or related  
consequential problems resulting from improper installation, adjustments, alteration, service, or maintenance are the  
refrigerator owner’s responsibility.  
1. Leak test gas supply piping and fittings at least once a year. This procedure should only be performed by your dealer or a  
Norcold service center. These facilities are familiar with gas refrigerators and propane gas systems.  
2. Check the main line gas pressure and adjust if necessary. The correct gas pressure is 11 inches water column. It is  
recommended that your dealer or a Norcold service center perform this task.  
3. Clean the refrigerator’s burner and burner orifice. This procedure is required once a year minimum and should  
only be performed by your dealer or a Norcold service center.  
4. Insure that the LP gas supply is Propane, not another fuel such as Butane or Butane mixtures. Question the facility in  
which you purchase your gas.  
5. Check the burner flame appearance during gas operation. Inspect burner electrode assembly to insure it is secure to burner bracket.  
11  
 
7. Inspect the flue of refrigerator’s cooling system. This area must be free of foreign materials. Foreign materials observed  
in the flue indicate the burner requires cleaning.  
8. Insure the area directly behind the refrigerator is not being used for storage. Keep the refrigerator area clear and free from  
combustible materials, gasoline, and other flammable vapors and liquids.  
9. Periodically inspect the ventilation system. The air passage from the bottom intake vent to refrigerator coils and from the  
refrigerator coils through the upper exhaust vent must be unobstructed.  
10. Inspect combustion seals (visual check without removing the refrigerator). Combustion seals are  
attached to the back surfaces of the refrigerator’s mounting flanges and must be continuous between the wall and the  
mounting flanges.  
11. Periodically inspect door seals.  
Refrigerator Storage  
When the refrigerator will not be in use for an extended (seasonal) period of time, it is recommended that all power to the  
refrigerator be disconnected. Unplug the refrigerator’s AC power cord from the wall receptacle and disconnect the 12 volt  
DC supply wires from the refrigerator’s power board located at the rear of the refrigerator. Clean the refrigerator interior and  
latch the doors in the storage position. After the extended shut-down period, the burner, burner orifice, and flue must be  
inspected before igniting the burner flame. These areas must be free from dust, spider webs, or other obstructions which might  
restrict the combustion system.  
Refrigerator Removal and Replacement  
To remove the refrigerator, disconnect both AC and DC power sources from the refrigerator. Turn off the propane gas at  
the main supply tank. Turn the refrigerator’s manual shut-off valve. Disconnect the gas supply piping at the manual shut-off  
valve. Remove the mounting screws securing the refrigerator to the enclosure. Remove refrigerator from the enclosure.  
Before reinstalling the refrigerator, inspect the areas behind the mounting flanges for damaged or missing seal strips.  
These seal strips serve as a combustion seal which isolates the living space of the vehicle from refrigerator’s combustion system.  
Reinstall the refrigerator by reversing the above procedures. After reinstalling the refrigerator, check the gas fitting connections for  
leaks. Do not check for leaks with an open flame. Use an approved leak-detection solution.
