WATER HOOKUP
READ ALL DIRECTIONS COMPLETELY BEFORE YOU BEGIN.
IMPORTANT:
In order to prevent possible leakage resulting in property damage, be sure:
1. If you are operating the refrigerator before installing the water connection, turn the ice maker to the OFF position to prevent operation without water.
2. Use copper tubing.
3. Install tubing only in areas where tempera­tures will remain above freezing.
4. All installations must be in accordance with local plumbing code requirements.
5. See the “Installation Guide” for further information.
COLD WATER SUPPLY
The ice maker water valve contains a flow wash­er which is used as a water pressure regulator. The ice maker needs to be connected to a cold water line with water pressure between 30-120 psi. If you have questions about your water pressure, call a licensed, qualified plumber.
If your refrigerator has a water filter car-
• tridge, it may further reduce the water pressure when used in conjunction with a reverse osmosis system. Remove the water filter cartridge.
CONNECTING TO THE REFRIGERATOR
1. Unplug refrigerator or disconnect power.
2. Remove the shipping tape from the gray, coiled water tubing on the rear of the re frigerator.
Style 1
1. Thread the provided nut onto the coupling on the end of the copper tubing.
Style 2
1. Thread the provided nut onto the water valve, as shown. First tighten the nut by hand, then tighten it with a wrench two more turns. Do not overtighten.
-
REVERSE OSMOSIS WATER SUPPLY
IMPORTANT: The pressure of the water sup-
ply coming out of a reverse osmosis system going to the water inlet valve of the refrigerator needs to be between 30-120 psi. If a reverse osmosis water filtration system is connected to your cold water supply, the water pressure to the reverse osmosis system needs to be a minimum of 40 - 60 psi. If the water system to the reverse osmosis water system is less than 40 - 60 psi:
Check to see whether the sediment filter
• in the reverse osmosis system is blocked. Replace the filter if necessary.
Allow the storage tank on the reverse osmosis system to refill after heavy us age.
FINAL CHECKS
1. Turn water supply valve ON and check for leaks. Tighten any connections or nuts that leak (including connections at the valve).
2. Plug in refrigerator or reconnect power.
-
NOTE: It may take up to 24 hours for the ice maker to begin producing ice.

THEORY OF OPERATION
OVERVIEW
The design of the 69ʺ tall counter-depth side­by-side refrigerator is similar to freestanding side-by-side refrigerators. There are, however, some very unique and important differences. This section will review the operation of this product and explain those unique differences.
The control system consists of an electronic user interface, located on the ice and water dispenser, an electronic control board, located at the left rear of the unit compartment, and thermistors, located in the refrigerator and freezer compartments. These controls com municate with each other, and manage virtually all of the functions of this refrigerator, with the exception of the in-door ice making feature.
-
3-1
Page 16
USER INTERFACE
The user interface allows the customer to adjust the temperatures, choose what kind of ice to be dispensed, and monitor the remain ing water filter capacity. There are also lockout modes for the temperature controls and the ice and water dispenser. The temperatures are only displayed in Fahrenheit.
Each function is described below.
ON/OFF—Press the keypad for 2 seconds to turn the unit on and off.
When the unit is turned “off”:
• Only the central decimal point shows in both temperature displays.
• All functions are disabled.
• All lamps and lights are off.
When the unit is turned “on”:
• All functions are restored at power-up.
• Temperature settings before power­down are remembered.
• Fast Freeze and/or Grocery Savor mode will be discontinued after power­up, if selected prior to power-down.
• The compressor will wait 7 minutes to start.
• The condenser fan will wait 1 minute to start after the compressor starts.
NOTE: At the first power-up, the control will start in the following DEFAULT operating

ELECTRONIC CONTROL BOARD
The main electronic control board is located at the right rear of the unit compartment (fac ing from the rear). The main electronic board communicates with the user interface. It also receives and reacts to feedback from other
THERMISTORS
Temperature is regulated with the use of two thermistors that provide feedback to the main control board. One thermistor is located on the back wall of the refrigerator section, and the other is located on the left wall of the freezer section.
NOTE: Thermistors are very reliable and sel­dom fail.
sources, such as water valves, thermistors, defrost bimetal, refrigerator and freezer light
­switches, and the air damper. The electronic control board directly controls, or supplies power to, virtually all functions of the refrigerator.
The refrigerator thermistor controls:
• Motorized air baffle (damper)
• Evaporator fan (only when the air baffle is open)
The freezer thermistor controls:
• Compressor
• Condenser fan
• Evaporator fan (only when the air baffle is closed)

Page 19
DEFROST OPERATION
Defrost is controlled by the main control board, and incorporates the use of the “pulsed” de frost. However, this defrost system is uniquely different than other Whirlpool electronic refrig erators.
• Defrost is initiated by a different set of criteria (listed below).
• The bimetal/thermofuse combination switches off the defrost heater, and provides additional defrost circuit pro tection.
• The defrost bimetal is placed on the neutral side of the defrost heater, and the thermofuse protects the “line” side of the circuit.
• The electronic control does not “time­out” and terminate the defrost cycle. Defrost is terminated only by the open ing of the bimetal switch contacts, or the opening of the thermofuse in case the bimetal fails.
• The bimetal opens at 45 and closes at 19°F ±5° (–7°C ±3°).
• The thermofuse will open at 162 (72°C).
The defrost cycle is initiated:
• When power is connected (after the initial power-up) to the refrigerator and the bimetal is closed (unit is cold).
• With no door openings.
- When 30 hours of compressor run
time, or 50 hours actual time, has passed since the last defrost cycle.
°F ±5° (7°C ±3°)

The following occurs when the defrost cycle is initiated:
-
-
When defrost bimetal thermostat opens:
- After 8 hours of cumulative compres sor run time.
• The compressor runs continuously for at least 8 hours.
• Cooling function switches OFF (com­pressor and both fans are OFF).
• The air-baffle/damper switches to the CLOSED position.
• The heater starts to heat the evaporator with the following timing:
- 5 minutes ON, 1 minute OFF.
- 3 minutes ON, 1 minute OFF repeat-
edly.
- Bimetal thermostat opens at 45°F ±5°
(7°C ±3°).
• The defrost heater is switched OFF.
• The compressor is activated after 7 minutes of drip time.
• The condenser fan is activated 1 minute after the compressor.
• The evaporator fan is activated after 10 minutes from bimetal opening, or 3 minutes after the compressor starts.
• The air baffle is opened 3 minutes after the compressor is activated, or a total time of 10 minutes from the bimetal opening.

Page 20
FAN OPERATION AND DELAY
Both the condenser and evaporator fan mo­tors operate on DC voltage. The control board supplies 115 volts AC to each motor, where it is converted to DC.
EVAPORATOR FAN
• Fan Start Delay—Fan is energized 3 minutes after the compressor starts.
• Fan Stop Delay—Fan is switched OFF 1 minute after the compressor stops.
IMPORTANT: Evaporator fan shuts off when either the refrigerator or freezer door is opened.
CONDENSER FAN
• Fan start delay—Fan is energized 1 minute after the compressor starts.
• Fan stops when the compressor shuts off.
POWER FAILURE / TEMPERATURE RISE
This product has no audible alarm. However, it will alert the customer of a long power outage, or temperature rise, if the temperature rises above 17.6 following will happen:
• The “alert” will only be indicated on the
• The freezer temperature display blinks
• The actual compartment temperature

are continued after power has been re­stored, i.e. FAST FREEZE, GROCERY SAVOR, and ice preference.
DEFAULT SETTINGS
If communication between the user interface and the control board is lost for more than 3 minutes, the user interface assumes the board is working correctly. The control board stores the current temperature settings, but will go into a “default mode,” and maintain preset temperatures. Once communication is restored, the stored settings are again used.
If communication is broken between the user interface and the control board during an “ON” cycle:
Electronic Control
• Default temperatures that will be main­tained are:
- Refrigerator section: 41
- Freezer section: 0
User Interface
• Freezer display flashes “CF” and Set Temp alternately (Communication Fault).
• Refrigerator display flashes the Set Temperature.
• The user interface keypads will be dis abled
• The ice maker will be disabled.
• The water filter status indicator light will blink, and the reset keypad will be disabled.
• The refrigerator and freezer interior lights will be off, except for the indicators above.
Default Operation If Thermistors Fail:
• Refrigerator thermistor fails:
- Damper and evaporator fan will be
cycled “on” 15 minutes and “off” 30 minutes.
• Freezer thermistor fails:
- Compressor and evaporator fan will

IN-DOOR ICE
IMPORTANT:
The In-Door Ice (IDI) feature and function on this product is the same as on all other IDI refrigerators.
Although physically interchangeable with other IDI electronic controls, these control boards are unique to this product and will not function in other IDI product, nor will other IDI controls function in this product.
If replacement controls are needed, order by model number.
The IDI control board and the ice maker are powered directly from the control board. This allows the main control board to monitor the ice maker water fill, and the closing of the freezer light switch when the door is opened. When the freezer door is opened, the ice maker is temporarily disabled.
The IDI diagnostic routine is also identical, and the checkout procedure is the same. For more information on diagnostics, or IDI design and function, refer to Job Aid #4322658A.

DIAGNOSTICS & TROUBLESHOOTING
WARNING
Electrical Shock Hazard
Disconnect power before servicing. Replace all parts and panels before operating. Failure to do so can result in death or electrical shock.
Diagnostics on this product are different than on other Whirlpool SxS refrigerators. Several error codes are available, however there is no “diagnostic mode” that can be “entered” on the electronic control to allow operation of each function separately.
Virtually all functional component testing must be performed similarly to a non-electronic product by verifying whether the component is “good,” or whether there is voltage present at the component. To know how these com­ponents function in this product, refer to the “Theory of Operation” section and the contents of this section.
IMPORTANT INFORMATION
Electronic Control Board
Virtually all components and functions are
electrically connected to and controlled by the Electronic Control Board both on the “line” and “neutral” side. The exception is the ice dispenser motor and the dispenser light. These components are directly connected to and controlled by the User Interface.
The majority of components and functions controlled by the Electronic Control Board are switched on the “neutral” side of the circuit. This means the “line” side of the circuit to the component(s) always has voltage potential.
User Interface Control Board
The User Interface Control Board is also energized by “line” and “neutral” circuits through the Electronic Control Board. Communication between the two boards is through the “TX” and “RX” circuits (refer to the Wiring Diagram and Strip Circuit).
Turning OFF the refrigerator turns off all of the interior and indicator lights except two dots (“.”) in the temperature displays.
6-1
Page 38
SUGGESTIONS ON DIAGNOSIS
IMPORTANT:
1. Check harness connectors for good con­tact.
2. Before replacing any component verify, whenever possible, that the component has proper continuity or resistance values. There must be proper power to operate the component.
Display Shows Error Codes
If error codes “C”, “d” or “CF” show in the display, refer to the “User Interface Failure Feedback” and “Component Testing” charts and check out the appropriate compo­nent(s).
Display Is Normal
Disconnect power for 10 seconds and re­connect power. If error code is displayed after 3 minutes, refer to the “User Interface Failure Feedback” and “Component Test­ing” charts, and check out the appropriate component(s).
If no error codes display and a malfunction is occurring, check or troubleshoot the fol lowing appropriate areas. Also refer to the “Component Testing” and “Troubleshooting” charts.
- Electrical system
- Restricted or lack of proper airflow
- Defrost system
- Unusual noises
- Cooling system

TECH TIPS
REMOVING THE ORIGINAL GASKET
NOTE: Replacing the gasket requires trimming
away only the soft part of the original foamed­in-place (FIP) gasket. Once the soft part of the FIP gasket is removed, a channel is exposed to install the service gasket.
To remove the original door gasket:
1. Cut the soft corner section of the FIP gas­ket.
3. Clean the remaining soft gasket burr from all sides of the door.

4. Clean the FIP gasket corner from the flash and burr that was created when the gasket was manufactured. The service gasket may now be installed.
2. Trim the soft part of the gasket with a knife around all four sides to expose the channel where the service gasket will be mounted.
