Introduction

2001 Arctica SxS models are being introduced in response to the requirement for more energy-efficient refrigerators by mid year 2001, along with having feature and operation enhancements.

One of the innovative features is the “CustomCool

bin. The system will provide optimum rapid cooling, (ExpressChillTM) , and safely thaw frozen foods (ExpressThawTM).

The main system components consist of two air dampers, a DC exhaust fan, reed switch, control board with buzzer, 3 color light diodes, a heater, and a thermistor. These components provide feedback to the main refrigerator processor board, and control the temperature and air flow in the “CustomCool

pan at the bottom of the fresh food compartment. A tray, which has a metal surface on one side is provided to place the foods on for chill or thaw.

The consumer sets the temperature from the touchpad controls at the top of the fresh food compartment, and selects mode of operation, and length of cycle. Air circulates from the freezer and is heated or maintained by the thermistor and control settings.

The CustomCool

pan is tightly sealed and has a tray which when placed in the metal plate facing down position, helps provide the chill, and in the metal plate up position helps to provide thaw. It also provides a method of catching liquid when thawing

”

and defrosting. The seals in their orginal position are extremely important in maintaining fresh food and feature temperatures.

”

Three selection choices are provided for the consumer:

• ExpressThaw

(maintains 41

Operation

Operation is initated by the consumer when the selection is made using the touch control at the top of the fresh food section. The user will have placed the chill/thaw tray in the proper position, metal plate facing down for chill, and up for thaw, and pan closed. A reed switch is mounted on the right side of the pan to provide a completed circuit when the pan is tightly closed. Open reed switch initiates a “beep” from the processor located in the CustomCool

pan assembly.

The warmed air is circulated through the pan to satisfy the temperature setting. Response to drastic temperature change is limited between two and ten minutes. The main control board located in the rear of the refrigerator will only respond to 8 degrees of temperature change per minute as determined by the resistance of the thermistor.

NOTE: DO NOT MANUALLY FORCE DAMPER DOORS OPEN, IT WILL DAMAGE THE ASSEMBLY

Based on users input one of the three selections is selected, with multiple inputs indexing to provide TIME, WEIGHT, or TEMPERATURE and countdown LED. One of three leds will light the selection portion of the touchpad to provide feedback and selection information to the user. The signal is then sent to the main processor and uses preset software parameters to provide DC inputs to the CustomCoolTM processor board mounted in the cover assembly.

When the selection is made a thermistor located in the side of the lower cover sends temperature information (resistance) to the main processor. The processor software determines what combination of dampers or heater need to be used to achieve the desired setting. (See thermistor temp chart on page 8).

A double door damper 12VDC operates in the

ExpressChill

mode, and both sides open to allow cold air to be drawn in and circulated within the lower cover. The single damper door is also closed to prevent loss of cold air and it is returned through the other side of the diverter back to the freezer compartment. The double door is cycled open and shut to maintain the temperature selection selected by the user, based on thermistor resistance feedback to the main processor board.

Airflow is directed from a diverter in the freezer side wall to provide cold air or drawn from fresh food compartment, and is circulated by a 12VDC fan in the front of the lower cover. When the thermistor is calling for warmer air the single damper motor is energized (12VDC) to open and the 30 watt strip heater is turned on.

CustomCoolTM feature has a third temperature preset selection which is SelectTempTM. It shows on the control panel as Citrus (43

F), Produce (340 F) and Meat (300 F). Note airflow, damper, and fan

operation as described below.

SelectTempTM-Meat Setting

NOTE: After ExpressThaw cycle is complete, the pan will reset to the MEAT setting (300 F) to help preserve thawed items until they are used.

Mechanical Assembly and Disassembly

To Service complete

CustomCool

pan and

Component access.

WARNING: MAKE SURE POWER IS DISCONNECTED!

To Service Components:

1. Remove 1 fresh food section.

2. Lift up and out to remove the CustomCool front chill cover (WR17X10915).

3. Remove two screws in front of CustomCool lower cover (WR31X10006), two screws on either side of the pan, and one screw in the back of the housing.

and 2nd bin from bottom of

7. Remove the freezer grill mullion (must be

removed prior to CustomCool

(WR02X10829) from the freezer side, by inserting a #2 Phillips screwdriver into the center of the diverter and turning the screw counterclockwise. (See illustration below)

service),

4. Remove two screws holding chill water reservoir assembly to back of refrigerator, and plastic deflector cover.

5. In the freezer compartment lift up on freezer baskets to remove (no need to remove rails), to completely provide access to the lower air duct cover.

6. Push in on the plastic lower freezer air tower, and then push up to remove. It is attached by two tabs one located on the backside of the freezer and the other rest on the air diverter asm.

8. The CustomCool assembly to the right to free from refrigerator wall. A large StyrofoamTM insert is located in the raised end of the upper cover housing, note position for replacement, it must be repositioned correctly to reassemble. The upper cover can be removed, components exposed.

9. Slots molded into the lower pan hold the fan, single damper assembly, and dual damper assembly. Pull up to release and push back into slot to reassemble.

assembly is now free, slide

NOTE: It is critical that all seals be replaced to

maintain proper temperatures in the CustomCoolTM pan and in the refrigerator.

Several variations in the lighting components at

the CustomCool

bin have been used in limited numbers. You may encounter a version that has light tubes, colored diodes on the pan PC board, or a colored insert. Service is obvious on each system. The terms CustomCoolTM has been referred to as QuickChillTM on some models.
