About Y our Refrigerator
Your refrigerator was thoroughly cleaned before shipment from
the factory. It is advisable, however, to clean the interior once
more before using. See “Cleaning”.
Storage Volume:
This refrigerator is made to store fresh and frozen foods and for
making ice.
DC68XX models 1.5 cubic feet capacity
DC85XX models 1.5 cubic feet capacity
DC39XX models 3.2 cubic feet capacity
DC73XX models 3.2 cubic feet capacity
Food compartment:
Start up the refrigerator and let it cool for eight hours before
loading with food. If the refrigerator does not start to cool down
after about two hours, contact your dealer or an authorized
Norcold Service Center.
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 freezer
plates:
- 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: When making ice, put the ice cube tray directly on the
freezer surface. Do not put other items on the ice cube
tray while the water is freezing. The water freezes
more rapidly if the power switch / thermostat is at the
coldest temperature setting.
Installation and Owner’s Manual 4

Operation
Controls:
- Make sure the air flow in the lower intake vent, through the
refrigerator condenser and coils 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 combustible materials, especially gasoline and
other flammable vapors and liquids.
Defrosting:
It is normal for frost to collect on the freezer plates of the
refrigerator. Excess frost decreases the cooling performance of
the refrigerator. Defrost the refrigerator as necessary:
- Put the power switch / thermostat in the OFF position.
- Remove all food from the refrigerator.
This refrigerator is made for refrigerating purposes and
operates on a 12/24 volt DC power supply when installed as
written in this manual.
On DC68XX and DC85XX models, the controls are located
in the right-hand upper rear corner of the food compartment
of the refrigerator.
On DC39XX and DC73XX models, the controls are located
inside the freezer door on the right-hand side of the freezer
compartment.
The refrigerator temperature is controlled by a thermostat [1],
located on the panel above the door. A green power light [2],
located on the panel comes on when the refrigerator is “ON”.
Number “1” is the warmest and number “5” is the coldest
thermostat position. For efficient operation, change the
thermostat according to the types of food stored and the
ambient temperature.
CAUTION: Do not operate the refrigerator when the
ambient temperature is higher than 110° F. Operation at
this temperature will start the over heating shut-off
device. See “Over heating shut-off device operation”.
Refrigerator Care Checklist
NOTE: Defrosting the refrigerator makes excess water inside
the refrigerator.
- Put dry towels (etc.) inside the refrigerator to absorb the
water.
- Put trays of hot water in the freezer until the frost is melted.
- Empty the drip tray in either of these two ways:
- Pull the drip tray forward to remove it from the refrigerator.
- Remove the drain plug from the drip tray and allow the
water to flow into another container.
- Remove the wet towels (etc.) and dry the interior.
- If removed, put the drip tray in the refrigerator.
- Put all food in the refrigerator.
- Put the power switch / thermostat at the temperature setting
that you wish.
Cleaning:
A good time to clean the refrigerator is just after you defrost it.
Your refrigerator will give you years of trouble free service if you
do these simple checks every three to six months:
- Defrost the refrigerator as necessary. See “Defrosting”.
- Keep the food compartment and the freezer clean. See
“Cleaning”.
- Make sure the door seals correctly. See “Door sealing“.
- Be aware of any cooling changes that are not because of
weather, loading, or thermostat changes. If changes occur,
contact your dealer or an authorized Norcold Service
Center.
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 scour-
ing 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.
Installation and Owner’s Manual 5
Page 6
- Dry with a clean cloth.
- Put all food into the refrigerator.
Troubleshooting
Door sealing:
If the door does not seal correctly, excess frost will collect inside
the refrigerator. Make sure the door seals correctly:
- Close the door on a piece of paper that is about the size of
a dollar bill (See Art00980).
- Gently pull the paper.
- You should feel a slight drag between the gasket and
the cabinet.
- Do this on all four sides of the door.
- If you do not feel a slight drag on the
paper, the door is not sealing correctly.
- Have your dealer or an authorized Norcold Service
Center correct the seal of the door
Refrigerator Maintenance Checklist
If you are not going to use the refrigerator for an extended period
of time, put the thermostat to the “OFF” position.
NOTE: Norcold is not responsible for installation, adjustment,
alteration, service, or maintenance performed by
anyone other than a qualified RV dealer or an
authorized Norcold Service Center.
Have a qualified RV dealer or an authorized Norcold Service
Center do these annual safety and maintenance checks:
- Make sure the DC voltage is 10.2 - 30.5 volts.
- The wire connections must be clean, tight and free of
corrosion. If any of these items are not correct:
- A voltage drop to the refrigerator will occur.
- The voltage drop will decrease the cooling performance of the refrigerator.
CAUTION: Disconnect the positive (+) DC power supply
wire from the battery before you do a “fast charge” of the
battery. Failure to disconnect the positive (+) power
supply wire from the battery during a “fast charge” can
cause damage to the refrigerator or other 12 volt DC
appliances.
If the refrigerator does not cool correctly:
- Make sure the power switch / thermostat is not in the OFF
position.
- Make sure that the refrigerator is correctly installed and that
the vents are not blocked.
- Make sure that the power source to the refrigerator is
serviceable.
- Make sure that the fuse or circuit breaker is intact (See
“Over current protection system” section).
- Make sure that the ambient temperature is not unusually
high (more than 110° F. / 43° C.) (See “Over heating shut-off
device operation” section).
- Make sure that the door is closed.
- If the weather is hot, make sure that the door is sealing
correctly.
- Make sure that the air circulation inside the refrigerator is
not decreased by foods or by shelves that are covered with
plastic, paper, etc.
- Make sure that hot foods were not placed in the fresh food
compartment of the refrigerator.
- Make sure that the freezer is defrosted.
After you make these checks, if the refrigerator does not
operate, contact your dealer or an authorized Norcold Service
Center.
Over heating shut-off device operation:
Operating the refrigerator in high ambient temperatures can over
heat the cooling unit and cause premature failure of the compressor. (See the label inside the refrigerator.)
To protect the cooling unit from over heating, the refrigerator will
automatically shut-off when the vehicle air temperature is higher
than 110° F. If shut off occurs, an audible alarm tone (an intermittent beeping) operates from the refrigerator.
To stop the audible alarm tone and restart the refrigerator, turn the
thermostat counterclockwise to the “OFF” position and then clockwise to the desired thermostat position.
The refrigerator will not restart until the air temperature is lower
than 110° F.
- Make sure the area at the rear of the refrigerator is free of
anything, especially combustible materials, gasoline, and
other flammable vapors and liquids.

Ventilation
1. Norcold recommends that you use the following wire and
fuse sizes:
This refrigerator is made for a built-in installation. Correct
ventilation is necessary for the correct operation of the
refrigerator and to increase the life of the refrigerator cooling
system.
Correct ventilation allows the natural air flow that is necessary
for good refrigeration. Cooler air comes in through a lower
intake vent, goes around the refrigerator coils where it removes
the excess heat from the refrigerator components, and goes out
through a side exhaust vent. If this air flow is blocked or
decreased, the refrigerator will not cool correctly.
The refrigerator has a fan which will operate only when the
ambient temperature is higher than approximately 95° F.
CAUTION: The refrigerator has built in vents on the right
and left sides. Make sure that the flow of air through
these vents is not blocked in any way. Blockage of air
through these vents can cause:
- shortened life of the refrigerator cooling unit.
- poor cooling performance of the refrigerator.
- continuous operation of the refrigerator.
- fast battery discharge.
- void of the refrigerator warranty.
- Measure the distance from the vehicle battery to the
refrigerator:
- If the distance is less than 12 feet, use 16 AWG wire
and a 10 Amp fuse.
- If the distance is between 12 and 20 feet, use 14 AWG
wire and a 10 Amp fuse.
- If the distance is more than 20 feet, use 12 AWG wire
and a 10 Amp fuse.
- Twist the lead wires to reduce the radio interference and
induction of a high voltage surge from the outside (See
Art01518).
Correct ................................................................................. 1
Incorrect ............................................................................... 2
Refrigerator ..........................................................................3
Battery .................................................................................. 4
Electrical equipment ............................................................ 5
Twisted lead wires...............................................................6
NOTE: This wiring is already in the vehicle. It is located
behind the wall trim panel.
2. Push the DC connector of the refrigerator completely into the
DC plug of the vehicle.
Connect the 12 Volt DC Supply
This refrigerator operates on 12/24 volts DC current from a
battery.
CAUTION: Only connect the refrigerator directly to the
battery. Because they often generate high voltage pulses
and cause transistor defects in the inverter, no other
switches, lead wires, or electrical equipment should
share the wiring between the refrigerator and battery.
When using either a converter or a battery charger, make sure
that they are connected in parallel between the battery and the
refrigerator. Do not use a converter or battery charger to supply
the DC power directly to the refrigerator because these two
devices do not supply filtered DC power (See Art01521).
Correct ................................................................................. 1
Incorrect ............................................................................... 2
Refrigerator ..........................................................................3
Battery charger or AC/DC converter , etc............................... 4
Transistorized DC power supply ......................................... 5
Condenser...........................................................................6
Battery .................................................................................. 7
As the distance from the vehicle battery to the refrigerator
increases, the correct AWG wire size also increases. If the wire
size is too small for the distance, a voltage drop occurs. The
voltage drop decreases the cooling performance of the refrigerator.
Install the Refrigerator
The refrigerator should be installed only on a solid surface in
the vehicle.
1. Align the mounting rails on the bottom of the refrigerator [1]
with the mounting rails on the bottom of the refrigerator
enclosure [2] (See Art01652).
2. Carefully push the refrigerator completely into the enclosure.
3. Open the door of the refrigerator.
4. Align the hole in the mounting rail on the bottom of the
refrigerator and the hole in the mounting rail on the bottom of
the refrigerator enclosure.
5. Put the mounting screw down through the opening [3] in the
bottom trim of the refrigerator (See Art01651).
CAUTION: Make sure that the mounting screw is not
cross-threaded in the mounting flanges. Cross-threading will damage the mounting flange and/or the screw.
6. Turn the mounting screw down into the mounting rails.
7. Tighten the mounting screw.
