REPORTED TO THE SELLING DEALER WITHIN NINETY (90) DAYS FROM DATE OF ORIGINAL RETAIL PURCHASE.
Viking Range Corporation uses the most up-to-date processes and best materials available to produce all color

Any sealed refrigeration system component, as listed below, or any automatic ice maker is warranted to be free
from defective materials or workmanship in normal household use during the third through the sixth year from
the date of original retail purchase. Viking Range Corporation, warrantor, agrees to repair or replace, at its option,

cover any food or medicine loss due to product failure. Warrantor is not responsible for consequential or

purchase upon request, and making the appliance reasonably accessible for service. If the product or one of its
component parts contains a defect or malfunction during the warranty period, after a reasonable number of
attempts by the warrantor to remedy the defects or malfunctions, the owner is entitled to either a refund or
replacement of the product or its component part or parts. Replacement of a component part includes its free

Operation
Settings and Functions
In order for your new refrigerator to work properly,
it is important that you understand its various
features, controls, and how to use them.
Power On/Off Switch (Power Interruption Switch)
The power on/off switch is located behind your
refrigerator’s top grille. It is used to turn the power
“OFF” when cleaning the refrigerator or changing
the light bulbs. Your refrigerator arrives from the
factory with the power interruption switch “ON”.
To turn power “OFF”, remove the center grille
blade. Press the power on/off switch to the “OFF”
position.
To turn power “ON”, press power on/off switch to
the “ON” position. Replace the center grille blade.
IMPORTANT: Be sure the power on/off switch is in the
“ON” position after cleaning or changing light bulbs.
Showroom Mode Initiation
Showroom mode allows electronic controls and
interior lights to function independently of the
refrigeration system.
To enter Showroom mode: Press and hold
the “ACTIVATE CONTROLS” pad. While
holding, press and hold the “HIGHER”
and “ALARM OFF” pad simultaneously.
One beep will be heard indicating that
sequence was entered properly. Continue
holding until three beeps are heard and
then the Blue LED two steps to the right of
the “HIGH TEMP” indicator will illuminate.
Showroom mode is entered.
To exit Showroom mode: Press and hold the
“ACTIVATE CONTROLS” pad. While holding, press
and hold the “HIGHER” and “ALARM OFF” pad

control panel, press “ACTIVATE CONTROLS” pad.
All other pads, except the “Alarm Off” pad, will
remain inactive until the ”ACTIVATE CONTROLS”
pad is pressed. Once activated, pad remains
programmable for at least ten minutes.
When you first plug your new refrigerator in, you
will find that five bars of nine are displayed. This
means that all unit controls are pre-set at the mid-
range setting. Wait 24 hours after plug-in for the
cabinets to reach this setting. After 24 hours, you
may adjust controls as desired. The warmest setting
displays one bar, while the coldest setting shows
nine bars.

temperature, simply press the
”ACTIVATE CONTROLS” pad, then
“REF TEMP” pad or “FRZ TEMP” pad.
Press the “HIGHER” or “LOWER” pad to
adjust temperature setting one level at
a time. Holding down the “HIGHER” or
“LOWER” pad adjusts temperature more
than one level at a time.
Key Press Confirmation
The key press confirmation is the “beep” heard when
a control pad is pressed. The confirmation can be
activate or inactive.
To activate the key press confirmation,
press and hold the “ACTIVATE CONTROLS”
pad for three to five seconds. Three beeps

household temperature thermostat that can read
temperatures between -5° to -50°F (-21° to 10°C).
Checking the Temperature (freezer)
Place the thermometer snugly between frozen
packages in freezer section. Wait five to eight
hours, then check the temperature. If the freezer

8 hours.
Checking the Temperature (refrigerator)
Place the thermometer in a glass of water in the
middle of the refrigerator. Wait five to eight hours,
and then check the temperature. If the refrigerator
temperature is not 38° to 40°F (3° to 4°C), adjust
the control one number at a time. Check again after
five to eight hours.
Automatic Ice Maker
After the refrigerator reaches normal temperature,
the ice maker fills with water and begins operating.
Under normal conditions, the ice maker will
produce seven to nine batches of ice per 24 hour
period.
Note: Allow 24 to 48 hours after installation before
looking for ice in your ice drawer. You should
discard the first three full drawers of ice produced
by your refrigerator, and should also throw out the
first drawer full of ice your refrigerator produces
after extended periods of non-use.
Door Stop Adjustment
Your refrigerator is factory set at 110° door stop
position. To change to either the 90° or 120°
position, remove the door stop pin located in the
bottom hinge using a 3/16” allen wrench. For 120°
