Defrosting and Cleaning the Refrigerator Interior
Your refrigerator is not frost free and will require periodic defrosting. To defrost, turn the refrige rator off. Empty the freezer
and the fresh food compartments. Placing a pan of hot water in the fre ezer 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.
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 so da to o ne 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 refr igerator interior.
This will help to prolong the life of the gaskets.
Do not use abrasive
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.

Door Alarm
If the lower door remains open and the interior light remains on for more than two mi nutes, 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

Page 9
Pressing and holding "MODE" button ( C) allows the user to cycle through fo ur 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 a re shown in the form of a thermome ter (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 s witch 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 op eration, and should therefore be use d only to maintain temperat ures when other mode s 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.
Operating Controls
Manual Mode
To operate in "MANUAL" mode, press and hold "MODE" button until "AUTO" disappears and th e 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 s ound and cod e 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 refrige rator te mper ature is too cold, a djust the thermostat up (war mer) 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 dia gnos tic s yste m which alerts the user to
a problem in any mo de of oper at ion. When a problem occurs within a given mode, the operating controls will revert to a stand-by mode in which an alarm
will sound and a diagnostic code will be displayed in
the cent er cont rol w indo w. The alarm will sound until
an alternate operating mode is selected. The diag-
nostic code will co nt in ue t o be di splay e d until the
controls are turned "OFF" and then back"ON".

Refrigerator Failure
Diagnostics
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 re frige rator 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 r ef rigerator is cycling properly. This will dete rm ine 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.

Burner Flame Inspection
Maintenance
The efficiency of your refrigerator while operating in the
gas mode is depe ndent up on the corr ect burn er flame . The
burn er flam e p rovides energy to the refrigerat or’s cooling
system.
The burner flame effici ency is a function of corre ct input
gas supply pressure, air input, and burner and burner
orifice cleanliness.
A visual check of the burner flame should be made
regularly. The flame should be sharp blue with a stable
burning appearance (Figure 11). If there is a constant
yellow component observed or if the flame appears erratic or unstable, switch the refrigerator to electr ic or turn the refrigerator
"OFF" and contact a qualified installer, service agency, or gas supplier.
