Safety Awareness
Read this manual carefully and understand the contents before you use the refrigerator.
Be aware of possible safety hazards when you see the safety alert symbol on the refrigerator and in this manual. A signal word follows
the safety alert symbol and identies the danger of the hazard. Carefully read the descriptions of these signal words to fully know their
meanings. They are for your safety.
This indication means a hazard, which if ignored, can cause dangerous personal injury, death, or much
property damage.
This indication means a hazard, which if ignored, can cause small personal injury or much property damage.
- The storage of ammable materials behind or around the refrigerator creates a re hazard. Do not use the area
behind the refrigerator to store anything, especially ammable materials (gasoline, cleaning supplies, etc.)
- Do not remove the round ground prong from any of the AC power cords. Do not use a two prong adapter or an
extension cord with any of the AC power cords.
- A circuit overload can result in an electrical re if the wires and/or fuses are not the correct size. Use only the wire
and fuse sizes as writtten in the “Installation Manual”.
- Incorrect installation, adjustment, change to, or maintenance of this refrigerator can cause personal injury, property
damage, or both. Have service and maintenance work done by your dealer or by an Norcold authorized service
center.
- Disconnect both the AC and DC power sources before doing any maintenance work on the refrigerator. All service
work on this refrigerator must be done by a qualied service technician.
- Do not bypass or change the refrigerator’s electrical components or features.
- When you discard an appliance, remove all doors to prevent accidental entrapment and suffocation.

Ignition and start up:
Control boards are extremely sensitive. Evidence of tampering or removal from protective case
will VOID any warranty.
Before ignition or start up of the refrigerator:
- Make sure the air ow in the lower intake vent, through the refrigerator coils and condenser, and out the upper
exhaust vent is not blocked or decreased.
- Make sure there are no combustible materials in or around the refrigerator.
- Make sure the DC voltage to the refrigerator is 12.0VDC
Air in the propane gas supply lines
For safety reasons,the refrigerators electronic controls are designed such that while operating in the LP
GAS mode, the trial for ignition (maximum amount of the time the gas valve and igniter can be left on
without a ame present) is limited to 30 seconds. When starting the refrigerator for the rst time, after
storage, or after replacing the propane gas tank, the propane gas supply lines can have air in them.
Due to air in the gas supply lines, the burner may not ignite within the 30 second time limit. In the event this
should happen the gas valve and igniter outputs will be turned off, the LP Gas mode will be “locked out”,
and the appropiate fault code will be shown in the display. See fault code section of this manual.
The gas lock out condition can be reset by powering the refrigerator OFF and then back ON, at which time,
a new 30 second trial for ignition will commence. It may be necessary to repeat this procedure several times
before expelling all the air from the LP gas supply line. If after repeated attempts, a ame is not established,
stop and consult your local dealer or Authorized Norcold Service Center.
Automatic Mode Operation:
- Touch and release the ON/OFF button [30] to turn the refrigerator
on. (See Art 02629).
- Touch the TEMP SET button [32] as needed to set the
temperature setting.

setting.
- Number nine(9) shown in the display [187] is the coldest
setting.
- If the AUTO icon [277] and AC PLUG icon [278] are lit up, it means that:
- 120 volt AC power is available to the refrigerator.
- The refrigerator is operating on AC electric power.
- After ten seconds, the backlight of the display goes off.
- If the AUTO icon and the FLAME icon [289] are lit up, it means that:
- 120 volt AC power is not available to the refrigerator.
- The refrigerator is operating on propane gas.
- After ten seconds, the backlight of the display goes off.

Owner’s Manual 9
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.
Ice Maker (N10LXIM, and NA10LXIM models)
The ice maker is assembled to the refrigerators at the factory as optional equipment. If the refrigerator does not have a factory installed
ice maker, one can not be added to the refrigerator at a later time.
The ice maker is fully automatic and will operate in ambient temperatures as low as 0° F. To allow operation at temperatures between
0° F and 32° F, the ice maker has a heater on the solenoid water valve and on the water line between the solenoid water valve and the
ice maker.
The water line heater does not protect the water supply line from the vehicle shut off valve to the solenoid
water valve on the back of the refrigerator.
When the freezer temperature of the refrigerator is low enough, the ice maker opens the water solenoid valve and lls the mold. The
ice maker ejects the frozen ice into a storage bin. As the storage bin lls, the ice raises the shut-off arm until it turns off the ice maker.
As you use the ice and lower the ice level in the storage bin, the shut-off arm also lowers. This turns the ice maker on and begins the
process of making ice.
The ice maker operates on:
- Cold potable water at a pressure of 15 psi - 125 psi.
- 120 Volts AC (108 VAC min. - 132 VAC max.).
Ice maker operation:
1. Make sure the separate (white) AC power cord which supplies AC to the ice maker is secure.
2. Open the water shut off valve of the vehicle.
Effects of Freezing Temperatures on Refrigerator Operation
A gas absorption refrigerator is not designed to operate in freezing temperatures. If the refrigerator is not equipped for low temperature
operation, and if the cooling system of the refrigerator is exposed to temperatures of 32° F. or lower for an extended period of time,
the refrigerator operation may be disrupted. The refrigerator operation will resume when the cooling system of the refrigerator warms
sufciently.
If the refrigerator is equipped for low temperature operation, the refrigerator will operate in temperatures down to 0° F.
Disrupted operation of the refrigerator, due to extended exposure to temperatures of 32° F. or lower, and any costs incurred to warm the
cooling system of the refrigerator are not covered by the Norcold limited warranty. Please contact your local RV dealer for information
about how to resume refrigerator operation or about how to equip your refrigerator for operation in freezing temperatures.
Do not change the installation or the venting of your refrigerator. Refrigerator failures, which are the result of changes to either the
refrigerator installation or to the venting, are not covered by the Norcold limited warranty.
CAUTION

Owner’s Manual 10
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 ame. See “Gas Flame Appearance”.
- Make sure the air ow 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 ammable vapors and liquids.
Defrosting
The cooling ns 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 ns. At regular intervals, the temperature control system
automatically melts most of the frost from the cooling ns. The water from the cooling ns 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.
Make sure that the ice maker arm can move freely and does not touch the frozen
foods in the freezer.
3. Push the ice maker arm down to the ON position [50] (See Art 01015).
If you operate the refrigerator without connecting the water supply line and/
or opening the water shut off valve of the vehicle, make sure the ice maker
arm is up in the OFF position.
4. Allow the freezer to cool enough and ice production will begin to ll the storage bin [61].
New plumbing connections and/or impurities in the water supply line after winterizing
can cause the rst ice to be discolored or have an odd avor.
5. To stop the ice maker, push the ice maker arm up to the OFF position [62].

Reinstall the Refrigerator
Your dealer or Norcold authorized service center must do this procedure.
Make sure the combustion seal is not broken, is completely around the refrigerator mounting anges, and
is between the mounting anges and the wall of the enclosure. If the combustion seal is not complete,
exhaust fumes can be present in the living area of the vehicle. The breathing of exhaust fumes can cause
dizziness, nausea, and in extreme cases, death.
1. Push the refrigerator completely into the enclosure.
2. Install the screws in the upper and then the lower mounting anges on the front of the refrigerator.
3. Install the upper and lower trim pieces to the mounting anges of the refrigerator.
4. Install the screws in the mounting ange at the rear of the refrigerator.
To avoid possible propane gas leaks, always use two wrenches to loosen and tighten the gas supply line
connections.
5. Attach the garden hose adapter to the water solenoid valve (N10LXIM and NA10LXIM models only).
6. Attach the gas supply line to the combination gas valve of the refrigerator.
7. Open the valve at the propane gas tank(s).
Do not allow the leak checking solution to touch the electrical components. Many liquids are electrically
conductive and can cause electrical shorts and in some cases, re.
8. Examine the gas supply line for leaks.
9. Connect the DC wiring to the refrigerator:
- Connect the DC wires to the refrigerator.
- Install the DC fuse or connect the DC wiring to the battery or the converter.
