Owner’s Manual 4
- Do not spray liquids near electrical outlets, connec-
tions, or the refrigerator components. Many liquids are
electrically conductive and can cause a shock hazard,
electrical shorts, and in some cases fire.
- The refrigerator cooling system is under pressure. Do
not try to repair or to recharge a defective cooling
system. The cooling system contains sodium chro-
mate. The breathing of certain chromium compounds
can cause cancer. The cooling system contents can
cause severe skin and eye burns, and can ignite and
burn with an intense flame. Do not bend, drop, weld,
move, drill, puncture, or hit the cooling system.
- At regular intervals, make sure that the refrigerator flue
the burner, the vent areas, and the ventilation air
pathway between the vents are completely free from
any flammable material or blockage. After a period of
storage, it is especially important to check these areas
for any flammable material or blockage caused by
animals.
CAUTION:
- The rear of the refrigerator has sharp edges and
corners. To prevent cuts or abrasions when working
on the refrigerator, be careful and wear cut resistant
gloves.

Owner’s Manual 5
For the best cooling performance:
- Let air move freely inside the entire food compartment.
- Do not cover the shelves with plastic, paper, etc.
To decrease the amount of ice that collects on the cooling fins:
- Cover all liquids and moist foods.
- Let all hot foods cool before putting them in the refrigerator.
- Do not open the door any longer than necessary.
Freezer compartment:
The freezer compartment is made to keep pre-frozen food
frozen and not to quick freeze food. Keep pre-frozen foods in
the freezer compartment.
NOTE: Do not put other items on the ice tray while the water is
freezing. The water freezes more rapidly if the
thermostat is at the COLDEST position.
Crisper(s):
The crisper(s) are located at the bottom of the fresh food
compartment and supply a storage area to preserve fruit and
vegetable freshness. Make sure that you always push the
crispers fully in.
NOTE: Do not wash the crispers in a dishwasher. The crispers
are not dishwasher safe.
Door bins:
You may put the door bins of the freezer and fresh food compart-
ment in a location that best meets your needs. To remove the
bins, lift them over the locator and pull them forward. To install
the bins, push them onto the locator.
NOTE: Do not wash the door bins and bin slides in a
dishwasher. The door bins and bin slides are not
dishwasher safe.
Adjustable shelves:
The shelves in the freezer and the fresh food compartment are
made so you can remove them or move them.
To remove or move the shelf of the freezer:
- Pull the shelf forward out of the slot.
- Push it fully into the slot that you wish.
To remove or move each shelf of the fresh food compartment:
- Remove the screw from the retainer of each shelf at the rear
of the refrigerator.
- Pull each shelf forward out of the slot.
- Push each shelf fully into the slot that you wish.
- Attach the retainer with the screw.
Door handles:
During travel, the door latch prevents the door from opening.
When closing each door, push the door toward the refrigerator
until you hear a “click” sound.
To open each door, pull the handle away from the refrigerator.
During storage, the storage latch prevents the door from
completely closing. Use it to prevent odors when the refrigera-
tor is stored for an extended period of time.
To operate the storage latch (see Art00991), open each door
about 1/2 inch and push the storage latch [1] into the cutout [2]
of the strike plate. Do not use the storage latch as a travel latch
because the doors will not be fully closed.
Interior light:
The interior light is at the top of the fresh food compartment. It
comes on when the refrigerator is ON and the door is open. To
replace the bulb:
1. Remove the DC power supply wires from the power board at
the rear of the refrigerator.
2. To remove the cover [1] , push it toward the rear of the
refrigerator (See Art00988).
3. Remove the light bulb [2] from the holder [3].

6. Connect the DC power supply wires to the power board at
the rear of the refrigerator.
Moisture reduction heater:
The refrigerator has a heater that prevents moisture from
forming on the center divider between the doors of the freezer
and the fresh food compartment. The heater operates only
when the refrigerator is ON.

Owner’s Manual 6
Temperature control system:
Although the refrigerator is not frost -free, it is made to limit frost
on the cooling fins. At regular intervals, the temperature control
system automatically melts most of the frost from the cooling
fins. The water from the cooling fins drains into a collection cup
that is attached to the back of the refrigerator. The heat of the
cooling system evaporates the water from the collection cup.
Backup operating system:
This refrigerator has a backup operating system. The backup
operating system allows the refigerator to continue to cool if the
temperature sensor of the refrigerator should fail.
If this failure occurs:
- The refrigerator automatically changes to the backup
operating system.
- The ON light flashes a fault code. See the “Fault
Codes” section of this manual.
- The backup operating system can overfreeze or thaw
the contents of the freezer and the fresh food compart-
ment.
- Make sure the temperatures of the freezer and the fresh
food compartment are satisfactory.
NOTE: If you open the door(s) too often, the tempera-
tures inside the freezer and fresh food compart-
ment do not become stable. Allow the refrigera-
tor to operate for about one hour after each
adjustment change before you examine the
contents. The number “5” is the coldest
temperature setting.
- If the temperature is too warm, push the tempera-
ture switch to the right to raise the temperature
setting by one number.
- If the temperature is too cold, push the tempera-
ture switch to the left to lower the temperature
setting by one number.
- Have the refrigerator serviced by your dealer or an Norcold
authorized Service Center as soon as possible.
Operating the Refrigerator Controls
Control panel:
The refrigerator control panel (see Art01560) is between the
freezer compartment and the fresh food compartment. A 12 volt
DC power supply is necessary for the control functions of the
refrigerator to operate. The refrigerator receives DC power from
the 12 volt system of the vehicle; either an auxiliary battery, a
converter, or the vehicle engine battery.
The selector switch [1] starts and shuts down the refrigerator:
- Push the selector switch to the AUTO position to start the
refrigerator in auto mode.
- Push the selector switch to the GAS position to start the
refrigerator on propane gas.
The temperature switch [2] controls the temperature adjustment
of the freezer and the fresh food compartment. The temperature
adjustment that you select does not change if the mode of
operation of the refrigerator changes.
- Push the temperature switch to the desired temperature
setting.
- The number “5” is the coldest temperature setting.
Refer to the “Display Codes” section of this manual.
Automatic mode operation:
When the refrigerator is in AUTO mode, it automatically uses the
most efficient energy source that is available for operation.
During operation, if a more efficient energy source becomes
available, the refrigerator controls change from the current
energy source to the more efficient energy source as follows:
- The first choice is AC operation if 120 volts AC is available to
the refrigerator.
- The second choice is propane gas operation if 120 volts AC
is not available to the refrigerator.
Removing air from the propane gas supply lines:
For safety reasons, the burner is made to ignite on propane gas
within a specified amount of time. When starting the refrigerator
for the first time, after storage, or after replacing propane gas
tank, the propane gas supply lines can have air in them. Due to
the air in the gas supply lines, the refrigerator may not ignite on
propane gas within the specified amount of time.
To remove the air from the propane gas supply lines:
- Make sure that all of the gas valves are open.
- Push the selector switch to the GAS position and the
refrigerator will start a 30 second trial for ignition.
- During the 30 second trial for ignition, the refrigera-
tor controls open the gas safety valve and the
igniter sparks.

Owner’s Manual 7
- During the 30 second trial for ignition, both the ON
and the GAS light show.
- If the ON light [3] and the GAS light [4] both show after
30 seconds, it means that the refrigerator is operating
on propane gas.
- At this time, all of the air is removed from the
propane gas supply lines and you may select
AUTO mode of operation if you wish.
- If the air in the propane gas supply lines prevents the
burner from igniting on propane gas after 30 seconds
the refrigerator controls close the gas safety valve and
the igniter stops sparking.
- Both the ON light and the GAS light flash about
once every second.
- Push the selector switch to the OFF position and
then to the GAS position and the refrigerator will
start a 30 second trial for ignition.
- Depending on how much air may be in the propane gas
supply lines, you may need to repeat the 30 second trial for
ignition two or three times.
- If the burner does not ignite on propane gas after two or
three attempts, stop and consult your local dealer or an
authorized Norcold Service Center.
Set the controls to automatic mode operation:
Push the selector switch to the AUTO position.
- If 120 voltsAC is available to the refigerator, the ON light [3]
shows.
- This means that the refrigerator is operating on AC
electric.
- If 120 voltsAC is not available to the refigerator, the ON light
and the GAS light both show.
- This means that the refrigerator is operating on
propane gas.
If the energy source is interrupted:
- The refrigerator shows a fault code.
- Refer to the “Fault Codes” section of this manual.
Set the controls to manual mode operation:
- Push the selector switch to the GAS position.
- When the ON light and the GAS light both show, this means
that the refrigerator is operating on propane gas.
If the energy source is interrupted:
- The refrigerator shows a fault code.
- Refer to the “Fault Codes” section of this manual.
Cooling unit sensing:
The controls have the ability to sense the operation of the
cooling unit. If the controls sense that the cooling unit has
stopped cooling:
- The heat sources to the cooling unit are turned off and are
locked out by the controls.
- The ON light flashes about five times every three seconds.
You can reset the controls and remove the fault code one time.
To reset the controls, shut off and then start the refrigerator.
- To turn off the refrigerator, push the selector switch to the
OFF position.
- To turn on the refrigerator, push the selector switch to the
AUTO position.
If you reset the controls and the fault occurs again before the
refrigerator completes a full cooling cycle:
- The heat sources to the cooling unit are turned off and are
locked out.
- The ON light flashes about five times every three seconds.
- This time you can not reset the fault. Have the refrigerator
serviced by your dealer or a Norcold authorized Service
Center as soon as possible.
Effects of High Altitude on Propane Gas
Operation
When you operate the refrigerator on propane gas at altitudes
higher than 5500 feet above sea level:
- You may experience reduced cooling performance of the
refrigerator.
- You may experience burner outages.
To avoid these possible problems, Norcold recommends that
you operate the refrigerator on AC when at altitudes higher than
5500 feet above sea level.

Owner’s Manual 8
A good time to clean the refrigerator is just after you defrost it.
Clean the inside of the refrigerator as often as necessary to
avoid food odors:
- Remove all food from the refrigerator.
NOTE: Do not use abrasive cleaners, chemicals, or
scouring pads because they can damage the
interior of the refrigerator.
- Wash the interior with a mild cleaner or a solution of liquid
dish detergent and warm water.
- Rinse with a solution of baking soda and clean water.
- Dry with clean cloth.
- Put all food in the refrigerator.
Cleaning
Defrosting
Refrigerator Care Checklist
Your refrigerator will give you years of trouble free service if you
do these simple checks every three to six months:
- Keep the food compartment and the freezer clean. See
“Cleaning”.
- Defrost the refrigerator as necessary. See “Defrosting”.
- Make sure the door seals correctly. See “Door Sealing“.
- Be aware of any cooling changes that are not because of
weather, loading, or gas control changes. If changes occur,
contact your dealer or service center.
- Make sure the gas supply is propane gas only and not
butane or a butane mixture.
- When in propane gas operation, examine the appearance
of the flame. See “Gas Flame Appearance”.
- Make sure the air flow in the lower intake vent, through the
refrigerator coils and condenser, and out the upper exhaust
vent is not blocked or decreased.
- Make sure the area behind the refrigerator is clear. Do not
use the area behind the refrigerator for storage of anything,
especially gasoline and other flammable vapors and
liquids.
The cooling fins of the refrigerator operate at below freezing
temperature and will naturally form frost from humidity, which is
always present in the air. The humidity inside the refrigerator
increases:
- with higher outside temperature and humidity.
- with the storage of non-sealed fresh foods or warm foods.
- with the amount of time that the door(s) are open.
- with any air leakage into the refrigerator.
Although the refrigerator is not frost -free, it is made to limit frost
on the cooling fins. At regular intervals, the temperature control
system automatically melts most of the frost from the cooling
fins. The water from the cooling fins drains into a collection cup
that is attached to the back of the refrigerator. The heat of the
cooling system evaporates the water from the collection cup.
It is normal for frost to collect inside the freezer. Excess frost
decreases the cooling performance of the refrigerator. Defrost
the refrigerator and freezer as necessary:
- Remove all food from the refrigerator.
- Turn the refrigerator OFF.
NOTE: Defrosting the refrigerator makes excess water inside
the refrigerator.
- Remove the drain hose from the drip cup at the rear of the
refrigerator.
- Put the drain hose into a half-gallon or larger container to
capture water.
- Put dry towels (etc.) inside the refrigerator and freezer to
absorb melted frost.
CAUTION: High temperatures can cause the inside
surfaces of the refrigerator to warp or melt. Do not use
pans of HOT water, a hair dryer, or any other high
temperature devices to defrost the refrigerator. Do not
use any hard or sharp objects to remove frost. Damage
to the interior of the refrigerator can occur.
- To increase the speed of defrosting, put pans of WARM
water in the refrigerator and freezer.
- Remove the wet towels (etc.) and dry the interior.
- Remove the drain hose from the large container and put the
drain hose back into the drip cup.
- Remove the large container from the enclosure.
- Start up the refrigerator.
- Allow the refrigerator to cool down.
- Return all food to the refrigerator.

Owner’s Manual 9
