The control allows three setting options.
Red Wine Use for the storage of red wines. This setting
will provide a storage temperature of 55°F(13°C), which
is optimum for the storage of red wine.
White Wine Use for the storage of white wines. This
setting will provide a storage temperature of 45°F(7°C),
which is optimum for the storage of white wine.
Custom Temp This setting allows the consumer to
customize the temperature when storing both red and
white wines. The custom temperature can be set any-
where between 40°F to 65°F(4°-18°C). The recom-
mended temperature when storing half red and half
white wine is 50°F (10°C). Pressing the
Custom Temp
pad will allow the Red Wine and White Wine pads to
be used as temp up and temp down pads.
When pressing a pad, the selected temperature will
momentarily show in the display, then revert to the
actual interior temperature.
The control pads can be locked by pressing the Red
Wine and Interior Light pads simultaneously for at least 3
seconds. The letters LOC will be displayed when a pad is
pressed. Exit lockout by pressing the Red Wine and
Interior Light pads again.
NOTE: In the event of a power failure, the unit will
default to the Red Wine setting.
NOTE: Moisture collecting and beading on outer glass is
NORMAL when the ambient temperature is 90°F, the
relative humidity is 85% and the control is set for a wine
temperature of 45°F or less.

To access the display board, remove the two Phillips
screws at the back of the tabletop cover. Lift the rear
slightly and pull the cover forward to clear the front lip.
Door
The door is available only
as an assembly. It
consists of three panes
of insulated glass, the
frame and door lock. The
lock is a part of the door
assembly and is not
serviceable. The door
is reversible. Refer to
the Owner’s Manual
(49-60201) for door
reversal instructions.
Door Gasket and Stop
The door gasket is a push-in style with a retaining
barb. It fits into a channel on the door frame. The stop
is held at the bottom of the door by two Phillips
screws. It allows the door to open to approximately
130°.
Light Bulb Circuit
The light is located in the ceiling at the front edge of
the cabinet. A light shield covers the bulb and is
attached by two Phillips screws. The bulb plugs
straight into the socket. It is a standard 5 watt, 12VDC,
available as WR02X11280 or at most automotive stores.
GASKET BARB
AND CHANNEL
NOTE: Do NOT use a bulb greater than 5 watts or
damage to the main board will occur.
Pressing the Interior Light pad on the display board
energizes a relay on the main control board in the
machine compartment. To test this circuit, check for
12VDC at CON3 on the main board. To test the wiring
harness, socket and bulb, look for approximately
3.6 ohms between the black and red wires when the
connector is removed from CON3.
Display Board
The indicator lights and pad switches for the control are
mounted to the display board. This display board is
referred to as a
tactile control since mechanical
switches are used rather than a touch membrane and
ribbon cable. The board receives 12VDC, but the majority
of components on the board operate on 5VDC. There are
two wiring connections. One five pin connector is routed
to the main control board in the machine compartment.
A second two pin connector is for the thermistor
mounted inside the cabinet on the back wall.
PAD SWITCHES

The display board is mounted to the tabletop by two
Phillips screws.
NOTE: There are plastic washers on the screws to
insulate the screw head from the board. Failure to
reinstall the washers could result in shorting the display
board.
Removing the board will expose the pad buttons housed
in the tabletop molding. When depressed, these buttons
engage the switches on the board. When servicing the
display, make certain the four buttons are fully seated
before reassembling.
Main Control Board
The main control board is enclosed in a plastic housing
to the right of the compressor.
To access the board, remove the Phillips screw on the
left side of the housing and slide left to disengage the
two mounting tabs. Pull the entire housing out and open
the cover by removing the two Phillips screws.
CONTROL BOARD
Due to the curved design of the tabletop, the buttons are
different heights and can be installed backwards. Make
certain to install the connecting bar towards the top of
the table.

NOTE: The display inlay is glued to front of the tabletop.
If the top requires replacement, make certain to order a
new adhesive inlay.

The main control board has three wiring connectors.
They are labeled CON1, CON2 and CON3. CON1 is the
120VAC input connection and the 120VAC output to the
CON1

compressor. CON2 is the 12VDC supply and feedback
from the display board. CON3 is the 12VDC output to the
interior light.

Service Test Mode
The electronic control has two built-in features during
normal operation. First, the temperature board only
updates the temperature displayed every 45 seconds.
This lag in time between updates eliminates any flicker
that might occur if the temperature was exactly between
two display points, such as 45.5°F flashing 45°F, then
46°F. Second, the control has a 4 minute delay in start-
ing the compressor if power is lost.
NOTE: This 4 minute compressor delay feature is
important to remember when diagnosing the compressor
circuit.
To override these two features, the control can be
placed into Service Test Mode. To enter this mode, press
and hold the
Red Wine, White Wine and Interior Light
pads for 5 seconds. At least two pads must be pressed
simultaneously. It may be easier to press Red and White
Wine simultaneously and while holding those pads,
press the Interior Light pad. After 5 seconds, the word
“SEr” will be displayed for 3 seconds, then a factory test
code will be momentarily displayed. Also, the
Red Wine,
White Wine and Custom Temp
LEDs will be on and the
interior light and compressor will be off. In the service
mode, the temperature lag feature is overridden and
updates from the thermistor are instantaneous on the
display. In addition, the
Custom Temp pad will toggle the
compressor on and off for testing. To exit the Service
Test Mode, depress the same three pads,
Red Wine,
White Wine
and Interior Light simultaneously for at least
5 seconds. Exiting the Service Test Mode is automatic
after 2 hours have elapsed.
Thermistor (Sensor)
During normal operation, the thermistor temperature is
sampled every 3 seconds and the display is updated
every 45 seconds. In order to better represent the actual
wine temperature rather than air temperature, the
display is “conditioned” in the software to avoid display-
ing wide changes in temperature, such as when the door
is opened. The display will update in one degree incre-
ments every 45 seconds. To determine the actual value,
enter the Service Mode.The thermistor can be checked
at the display board. Unplug the 2 wire connector and
measure the resistance across the two terminals of the
wiring harness. The thermistor has a negative coeffi-
cient. As the temperature goes up, the resistance value
goes down. At the specified temperature, it should read
approximately the following ohms:
32°F (0°C) 13.3K ohms
40°F (4.4°C) 11.8K ohms
45°F (7.8°C) 9.5K ohms
50°F (10°C) 8.8K ohms
60°F (15.5°C) 7.1K ohms
68°F (20°C) 6.0K ohms
77°F (25°C) 4.9K ohms
THERMISTOR
NOTE: If the thermistor fails to open, the control will
display a temperature of 32°F (0°C).
If the thermistor is shorted, the control will display a
temperature of 99°F (37.2°C).
If either of these conditions occur, the wine chiller is
programmed to run approximately 25% of the time. This
is equivalent to about 55°F (Red Wine) at 90°F ambient
and 45°F (White Wine) at 70°F ambient.
The thermistor is located behind a plastic cover on the
evaporator. Grasp the cover on the right edge and slide
to the right while pulling towards you. The thermistor
has a short harness plugged into the back of the liner.
The connector has a flat edge for correct orientation.
Make certain it locks with a “click” when reinstalling.

Evaporator
The evaporator plate is screwed to the back interior wall
with four Phillips screws.
To replace the evaporator, remove the screws and rotate
the left edge towards the front of the cabinet. The heat
exchanger is foamed into the cabinet and cannot be
replaced. To prevent damage to the plastic liner, the use
of LOKRING fittings are recommended. The suction line
requires a 1/4" to 1/4" brass connector (WR97X10031).
The capillary connector is a .079 to 5/32" brass connector
(WR97X10037).

EVAPORATOR
Electromagnetic Interference (EMI)
There is a very low possibility of interference if the
consumer places a television or radio directly on the
tabletop of the wine chiller. In these rare instances, two
ferrite filters can be installed. Part number WR49X10071
contains two filters. The ferrite filter housing wraps
around the power cord and locks with two snap tabs.
The filters are designed to prevent the power cord from
acting like an antenna. They should be installed between
the power cord strain relief and the main control board.
