Installation and Owner’s Manual  7

Read and understand the following maintenance sections of
this manual.

Have a qualified RV dealer or an authorized Norcold Service
Center do these annual safety and maintenance checks:

-  Make sure the AC and DC voltages are correct (See the

“Electrical current necessary” section).

-  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 perfor-

mance of the refrigerator.

  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.

-  Make sure the area at the rear of the refrigerator is free of

anything, especially combustible materials, gasoline, and
other flammable vapors and liquids.

-  Make sure the 

power switch / thermostat is not in the OFF

position.

-  Make sure the power switch / thermostat is at the tempera-

ture setting that you wish.

-  Make sure that the power source(s) to the refrigerator is

serviceable.

-  Make sure that the fuse or circuit breaker is intact (See

“Overcurrent protection system”)

-  Make sure that the refrigerator is correctly installed and that

the built in vents are not blocked.

-  Make sure that the ambient temperature is not unusually

high (more than 110° F. / 43° C.) (See “Overheating shut-off
device operation”).

-  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.

Operating the refrigerator in high ambient temperatures can over
heat the cooling unit and cause premature failure of the compres-
sor (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 intermit-
tent 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 clock-
wise to the desired thermostat position.

The refrigerator will not restart until the air temperature is lower
than 110° F.

Your refrigerator has an over current protection system in the
electronic circuit to prevent damage to the inverter which may
occur due to a reverse polarity connection.

If the refrigerator does not operate and the green power light
does not come on, check the  fuse, which is located in-line with
the DC connector, and the polarity of the DC power supply.  If the
refrigerator still does not operate, another problem can exist in
the inverter.  Have an authorized Norcold Service Center check
the refrigerator.
