Introduction
This new Arctica dual evaporator refrigerator has the following features:
Separate freezer and fresh food evaporators with independent cooling.
• No damper/air inlet assembly in the fresh food section creates more usuable space on the top shelf.
Greater fresh food humidity to keep food fresher, longer.
20% less freezer defrost for better food preservation.
3-Way valve to direct refrigerant fl ow.
Nearly silent, only 30 dBA.
The 3-speed compressor is controlled by an inverter that receives input from the low voltage DC side of the main control board. The inverter always has 120 VAC applied when the refrigerator is connected to power. The main control board still makes compressor decisions based on the input of thermistors, door-open time, and input from the temperature control panel. The main control board also operates the condenser fan, fresh food fan, freezer fan and adaptive defrost.
The most signifi cant difference from previous models is that the freezer and fresh food evaporators are separate. The 3-way valve directs refrigerant fl ow to each evaporator as needed. The fresh food section no longer relies on the freezer evaporator for cooling. The evaporators are controlled separately by the main control board through the 3-way valve.

Control Features
The temperature controls are preset in the factory at 37°F for the refrigerator compartment and 0°F for the freezer compartment.
Allow 24 hours for the temperature to stabilize to the preset recommended settings.
The temperature controls can display both the SET temperature as well as the actual temperature in the refrigerator and freezer.
The actual temperature may vary slightly from the SET temperature based on usage and operating environment.
Setting either or both controls to OFF stops cooling in both the freezer and refrigerator compartments, but does not shut off electrical power to the refrigerator.
To change the temperature, press and release the WARMER or COLDER pad. The SET light will come on and the display will show the set temperature.
To change the temperature, tap either the WARMER or COLDER pad until the desired temperature is displayed.
Refrigerator temperatures can be adjusted between 34°F and 44°F and the freezer temperatures can be adjusted between –6°F and +6°F.
Once the desired temperature has been set, the temperature display will return to the actual refrigerator and freezer temperatures after 5 seconds. Several adjustments may be required. Each time you adjust controls, allow 24 hours for the refrigerator to reach the temperature you have set.
To turn the cooling system off, tap the WARMER pad for either the refrigerator or the freezer until the display shows OFF. To turn the unit back on, press the COLDER pad for either the refrigerator or freezer. The SET light will illuminate on the side you selected. Then press the COLDER pad again (on the side where the SET light is illuminated) and it will go to the preset points of 0°F for the freezer and 37°F for the refrigerator.
Setting either or both controls to OFF stops cooling in both the freezer and refrigerator compartments, but does not shut off electrical power to the refrigerator.

About TurboCool.
How it Works
TurboCool rapidly cools the refrigerator
compartment in order to more quickly cool foods. Use TurboCool when adding a large amount of food to the refrigerator compartment, putting away foods after they have been sitting out at room temperature or when putting away warm leftovers. It can also be used if the refrigerator has been without power for an extended period.
Once activated, the compressor will turn on immediately and the fans will cycle on and off at high speed as needed for eight hours. The compressor will continue to run until the refrigerator compartment cools to approximately 34°F (1°C), then it will cycle on and off to maintain this setting. After 8 hours, or if TurboCool is pressed again, the refrigerator compartment will return to the original setting.
How to Use
Press TurboCool. The refrigerator temperature display will show TC.
After TurboCool is complete, the refrigerator compartment will return to the original setting.
NOTES: The refrigerator temperature
cannot be changed during TurboCool.
The freezer temperature is not affected during TurboCool.
When opening the refrigerator door during TurboCool, the fans will continue to run if they have cycled on.
About the ice and water dispenser. (on some models)
To Use the Dispenser
Select CUBED ICE , CRUSHED ICE or WATER .
Press the glass gently against the top of the dispenser cradle.
The spill shelf is not self-draining. To reduce water spotting, the shelf and its grille should be cleaned regularly.
If no water is dispensed when the refrigerator is first installed, there may be air in the water line system. Press the dispenser arm for at least two minutes to remove trapped air from the water line and to fill the water system. To flush out impurities in the water line, throw away the first six glassfuls of water.
CAUTION: Never put fingers or any other objects into the ice crusher discharge opening.
Locking the Dispenser
Press the LOCK CONTROL pad for 3 seconds to lock the dispenser and control panel. To unlock, press and hold the pad again for 3 seconds.
Dispenser Light
This pad turns the night light in the dispenser
on and off. The light also comes on when the dispenser cradle is pressed. If this light burns out, it should be replaced with a 6 watt 12V maximum bulb.
Quick Ice
When you need ice in a hurry, press this pad to speed up ice production. This will increase ice production for the following 48 hours or until you press the pad again.
Door Alarm
To set the alarm, press this pad until the indicator light comes on. This alarm will sound if either door is open for more than 3 minutes. The light goes out and the beeping stops when you close the door.
Spill Shelf

Dispenser Light
The LIGHT pad turns the dispenser light on and off. When the light is turned off, it will fade out. The dispenser light will come on automatically when the dispenser cradle is depressed and will fade out 5 seconds after it is released. The LIGHT pad will not turn off the light during dispensing.
Dispensing Functions
The water, crushed ice, and cubed ice functions are controlled by the main control board. To select a function, press the appropriate pad on the dispenser. The LED will light to identify the selection.
To dispense ice cubes or crushed ice, choose the appropriate pad and depress the dispenser cradle. The solenoid and linkage assembly will open the ice chute duct door to dispense the ice. If cubed ice is selected, a solenoid located behind the ice bucket will lift a rod along the side of the bucket. This rod pulls a fl apper away from the cutter blades, allowing cubes to bypass the ice crusher. The dispenser duct door will remain open for 3 seconds after dispensing to allow all ice to clear the chute.
The dispenser light will come on automatically when the dispenser cradle is depressed and will fade out 5 seconds after it is released.
Dispenser Lock
When the dispenser system is locked, no dispenser command will be accepted. This includes the dispenser cradle and will prevent accidental dispensing that may be caused by children or pets. If a pad or the cradle is depressed with the system locked, it will be acknowledged with three pulses of the LOCK LED accompanied by an audible tone.
To lock or unlock communication between the dispenser and main control board, press the LOCK pad and hold it for 3 seconds. The LOCK LED will fl ash while the LOCK pad is pressed. When the communication is locked, the LOCK LED will be illuminated.
The status of other functions selected prior to the initiation of the lock feature will be displayed. If the lock is engaged while a mode is active, the LED will remain on until that mode times out.
If the lock is engaged when the fi lter timer expires, the LED will come on but cannot be reset until the lock is turned off.
The lock feature will be restored in the event of a power disruption.
Liner Protection Mode
The dual evaporator model has separate liner protection modes for each section. The specifi c evaporator fan (freezer or fresh food) will start and run on high speed if the door has been open for 3 minutes.
This mode is controlled by 2 timers. Timer #1 monitors door-open time. A 3-minute door-open count begins when the door is opened. If 3 minutes elapse before the door is closed, the liner protection mode will become active. Once the door is closed, timer #1 resets and liner protection mode goes into standby. In standby, normal fan operation resumes and timer #2 begins a 3-minute door-closed count. If 3 minutes elapse without a door opening, liner protection mode will completely deactivate. If a door is opened within the timer #2 door-closed count, the remaining time in the door-closed count will be deducted from the timer #1 door-open count.

Evacuation and Charging Procedure
WARNING:
Before cutting or using a torch on refrigerant tubes, recover the refrigerant from the system using approved recovery equipment.
4. Open the ball valve. Recover the purge/ sweep charge using the recovery pump and the refrigerator compressor until a 20-in. vacuum is attained. Close the ball valve and remove the recovery hose.
5. Charge the system with the exact amount of R-134a refrigerant specifi ed.
Never charge new refrigerant through the purge valve. This valve is always located on the high pressure side of the system.
Never apply heat from any source to a container of refrigerant. Such action will cause excessive pressure in the container.
Always wear goggles when working with refrigerants and nitrogen holding charge in some replacement parts. Contact with these gases may cause injury.
1. Attach the hose from the R-134a charging cylinder to the process tube port on the compressor.
2. Evacuate the system to a minimum 20-in. vacuum using the refrigerator compressor and recovery pump, which is attached to the new drier assembly.
3. Turn off the recovery pump. Close the ball valve on the hose connected to the high-side port connection. Add 3 ounces of R-134a refrigerant to the system. Let the refrigerator operate and circulate the refrigerant for 5 minutes.
6. Disconnect the power cord to the refrigerator. This allows the pressure to equalize. After 3 to 5 minutes, the low side pressure will be positive and then the hose-to-charging port can be disconnected.
7. Using an electronic leak detector, check all brazed joints and both schrader ports. Reinstall caps to schrader.

Fresh Food Evaporator Thermistor
The fresh food evaporator thermistor (part # WR55X10025) is located in an aluminum thermal block on the back of the evaporator. It is attached to the fresh food evaporator by a wire tie. See
Fresh Food Evaporator for accessing instructions.
If the fresh food evaporator thermistor is either open or shorted, the main control board defaults to a fi xed defrost cycle of 1 hour at high speed fan.
Thermal Block
Thermistor
Insert the new thermistor into the thermal block. Add RTV102 silicone to hold the thermistor in place. Make certain to wire tie the thermal block back to the evaporator.
Fresh Food Evaporator Fan
A variable speed 12 VDC motor is mounted in front of the fresh food evaporator. The fan and evaporator cover are replaced as a complete assembly.
Barbs on the molded housing hold the thermistor in the thermal block.
Barbs
Replacement
Should the evaporator thermistor require replacement, splice a new thermistor into the harness using plastic bell connectors (part # WR01X10466). Fill the connector with RTV102 silicone as shown in the illustration.
When activated, the fresh food evaporator fan recirculates the air in the fresh food compartment, providing cooling independent of the freezer evaporator fan.
The main control board gathers information from the fresh food thermistors to determine when, and at what speed, fan operation should occur.
A constant 13.6 VDC is provided to the fan from the main control board and switching occurs on the neutral side.
Speed is regulated by pulse width modulation on the common side of the fan. When operating, the common side of the circuit is pulsed open and closed. This pulsing produces effective voltage being received at the motor, which is equivalent to a reduction in voltage. Fan speed is selected and maintained by the main control board regulating the length and frequency of the 13.6 VDC pulse.
