Refrigerant Flow

The compressor compresses R134a refrigerant, raising its pressure and temperature. Refrigerant vapor is pumped out the compressor discharge, down through the drain pan loop, up through the condenser coil, around the condenser loop, through the drier, and into the 3-way valve. By the time the refrigerant has reached the 3-way valve, it has completely condensed into a liquid. Depending upon whether the main control board opens the 3-way valve to the freezer evaporator

FRESH FOOD AND FREEZER SECTION COOLING

Condenser Fan

or the fresh food and freezer evaporators, refrigerant ﬂ ows through the appropriate capillary tube and into the evaporator. As the high pressure liquid passes through the capillary and enters the low pressure evaporator, it quickly expands and evaporates. During evaporation, the refrigerant absorbs heat, becoming cold. At the outlet of the freezer evaporator, an accumulator captures any remaining liquid, allowing only low pressure vapor to return to the compressor through the suction line.

Evacuation and Charging Procedure

WARNING:

• Before cutting or using a torch on refrigerant tubes, recover the refrigerant from the system using approved recovery equipment.

• 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 a 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.

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.

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 ports.

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.

Ice Dispenser

The water, crushed ice, and cubed ice functions are controlled by the power control board (PCB).

To select a function, press the appropriate pad on the dispenser. The LED will light to identify the selection. To dispense the selected item, depress the dispenser pad located in the recessed area. With any ice selection, the duct door motor and cam will open the chute door, and upon release, delay its closure. A motor and cam replace the more familiar duct door solenoid.

The icemaker water line is routed from the water valve, through the machine compartment, and to the icemaker ﬁ ll tube. The water tank line is routed from the water valve, through the back of the machine compartment, down the back of the cabinet, through the bottom of the unit, and into the fresh food compartment where it is attached to the water tank. The water tank holds approximately 35 oz of water.

The door dispenser supply line is routed from the cold water tank, through the bottom of the unit, and into the freezer door.

When

CUBED is selected on the ice dispenser

control panel, the cube motor behind the ice bin rotates. The motor cam lifts a linkage arm allowing the ice to bypass the crusher blades. A motor and cam replace the ice cube solenoid.

Dispenser Light

The light bulb is a 6-watt 12 VDC bulb (WR02X10675). Check for 12 VDC at CN03 on the terminal board, between pin #4 and pin #5, with the dispenser switch in the closed position.

Dispenser Heater

Main Switch

The dispenser cavity heater is non serviceable. If defective, the freezer door must be replaced.

The amount of time the heater is energized is based on ambient temperature (provided by the ambient thermistor). Below 46°F (8°C), the heater is constantly on. Between 46°F (8°C) and 80°F (27°C), the heater cycles on and off with the compressor. Between 80°F (27°C) and 98°F (37°C), the heater cycles on for 5 minutes and off for 5 minutes, while the compressor is running. When the compressor is off, the heater cycles on for 5 minutes and off for 25 minutes. Above 98°F (37°C), the heater cycles on and off, with the compressor.

Check for 120 VAC at CN08 on the terminal block, between pin #4 and pin #5, when the heater should be energized or when the refrigerator is in test mode 0 9 (see

Diagnostics). Heater resistance is approximately

Service

1.9K Ω.

The main switch is mounted to a bracket at the front of the machine compartment. The main switch opens both the line voltage and neutral

side to the refrigerator.

Main Switch

When the refrigerator is plugged in, the line voltage and neutral is supplied at CN01, between pin #1 and pin #2.

Door Water Line Replacement

To remove the existing water line, remove the screws from the water line retainer at the dispenser, then pull the retainer off the tubing.

From the bottom of the door, disconnect the water line and pull it down and out.

To install the new water line, soak the new line in hot water (to make it pliable) and insert it into the door at the dispenser location. Feed the water line into the door, until it emerges through the bottom hinge as shown in the photo below. (The stainless steel panel is shown pulled away from the door for clarity).

Caution: Do NOT connect or disconnect CN1 connector with power applied. Always turn off power at the main switch to avoid arcing at connector terminals.

CN01

Note: On custom panel models, it may be necessary to remove the door handle and slide the panel to the right to feed the water line past the bend.

Compressor

The refrigerator contains a variable speed inverter compressor (2200 to 3800 RPM). The inverter is part of the main power control board (PCB). The compressor will start (if required) one minute after power is applied to the refrigerator. Compressor operation is determined by the fresh food and freezer thermistors.

OVER-LOAD PROTECTOR

Refrigerant Charge

The refrigerant used in the sealed system is R134a. Proper system charge is 8.11 oz.

Heat Exchanger

The heat exchanger is located at the rear of the machine compartment, behind the compressor. The tubing is coiled and foamed into a galvanized cover. A replacement heat exchanger and cover come as a complete assembly.

Should the compressor fail to start when required, check the compressor windings and associated wiring harness BEFORE checking for a power control board (PCB) problem. The compressor resistance between each pin should be approximately 12 Ω. Measure the resistance at CN08, between pin #7 (black wire), pin #8 (purple wire), and pin #16 (blue wire).

A thermal overload, designed to protect the compressor, is mounted within the compressor terminal cover. The overload will open at 257°F (125°C) and close at 156°F (69°C). The overload should be checked at CN08, between the pin #14 and pin #15 (light blue wires).

Note: An open compressor overload will prevent the main control board from operating. If voltage is present at CN01, and the refrigerator is dead (except for the interior lights), check to make certain the thermal overload is closed.

To test whether the 3-way valve is receiving a signal from the power control board:

1. Turn the power OFF at the main switch for at least 10 seconds.

2. Place a ﬁ nger on top of the valve.

Caution: Be careful of the condenser fan and any exposed wires.

3. Turn the main switch back on. You should feel movement, and you may hear the 3-way valve move to the home position.

4. If movement is detected, the power control board and valve coil should be OK.

When replacing the 3-way valve, note the red sleeve on the valve tube. This tube connects to the freezer capillary. The corresponding freezer capillary has red paint above the braze joint.

Thermistors

The main control board uses input from 5 thermistors:

• Ambient

• Freezer

• Fresh Food

• Freezer Evaporator

• Fresh Food Evaporator

The thermistors have a negative coefﬁ cient. As the temperature increases, the thermistor’s resistance decreases.

Testing

The most accurate method of testing a thermistor is to place it in a glass of ice water for several minutes. The thermistor should read approximately 13K Ω in the glass of 33°F ice water.

Note: Thermistors can also be checked for an open or shorted condition by using the diagnostic mode (see

Ambient Thermistor

The ambient thermistor measures room temperature and is clipped to the back of the dispenser cover. Check for thermistor resistance

Thermistor Emergency Operation

If the freezer thermistor opens (or shorts), the unit defaults to the freezer evaporator thermistor. The compressor and freezer fan cycle off when the freezer evaporator temperature is -22°F (-30°C) or colder. The compressor and freezer fan cycle on when the freezer evaporator temperature is

-2°F (-19°C) or warmer.

If the fresh food thermistor opens (or shorts), the fresh food cooling operation defaults to the freezer thermistor. Refrigerant will ﬂ ow through the fresh food evaporator any time the freezer evaporator is cooling. The fresh food fan will cycle off once the fresh food evaporator thermistor reaches 5°F (-15°C) or colder.

– 39 –

Defrost Cycles

The refrigerator incorporates two different methods of defrost. Once the compressor has accumulated 2 hours of compressor run time, and certain conditions are satisﬁ ed, the fresh food evaporator goes through a "natural defrost" cycle. In addition, at a speciﬁ c time interval, both the fresh food and freezer evaporators go through a

"heated defrost" cycle.

Natural Defrost (Fresh Food Only)

Once the fresh food temperature is satisﬁ ed, natural defrost occurs on the fresh food evaporator, if the following conditions have been met:

• The compressor has accumulated 2 hours of run time.

• The ambient room temperature is above 66°F (19°C).

• The freezer temperature is satisﬁ ed.

If the above conditions have been met, when the fresh food temperature is satisﬁ ed, and the compressor cycles off, the 3-way valve will open to both the fresh food and freezer evaporators. This allows the refrigerant within the system to equalize back through the evaporators. This warm thermal mass (refrigerant) ﬂ owing through the evaporators helps to remove any frost buildup on the fresh food evaporator (it has very little impact on the freezer evaporator due to the freezer temperature). In addition, when the fresh food evaporator thermistor is below 23°F (-5°C), the fresh food evaporator fan will run to help move air across the evaporator. Once the thermistor reaches 28°F (-2°C), the fan will cycle

off.

Note: If the compressor is still cooling the freezer section when the fresh food cycles off, or the ambient room temperature is below 66°F (19°C), natural defrost will not occur.

Heated Defrost

In normal cooling operation (normal food load, door openings, etc.), the power control board (PCB) will energize the fresh food defrost heater every 5 hours of compressor running time and the freezer defrost heater every 10 hours of compressor running time.

For example, after approximately 10 accumulated hours of compressor running time, the freezer evaporator will have gone through one defrost cycle, and the fresh food evaporator will have gone through two defrost cycles.

The fresh food heater cycles off when the fresh food evaporator thermistor reaches 63°F (17°C). The freezer heater cycles off when the freezer evaporator thermistor reaches 68°F (20°C). The compressor and fans do not operate when either section is defrosting, regardless of the cabinet temperature. There is a 10-minute dwell period after the heater cycles off.

Note: Upon initial power-up, the fresh food and freezer go into heated defrost simultaneously, after 4 hours of accumulated compressor run time.

During unusual cooling situations where there are no door openings (such as vacations), the time between heated defrost cycles may increase. If the ambient room temperature is above 82°F (28°C) and there are no door openings, the fresh food defrost occurs every 8 hours, and the freezer defrost occurs every 16 hours. If the ambient room temperature is below 82°F (28°C), defrost occurs at the normal intervals – fresh food defrost every 5 hours and freezer defrost every 10 hours of accumulated compressor run time.

Thermistor Error Defrost Operation

If either evaporator thermistor fails (open or shorted), the power control board (PCB) defaults to a timed defrost cycle based on cabinet temperature.

If the freezer evaporator thermistor fails (open or shorted) and the freezer temperature is below 27°F (-3°C), the freezer defrost heater will be energized for 20 minutes. If the freezer temperature is above 27°F (-3°C), the heater will not come on.

If the fresh food evaporator thermistor fails (open or shorted) and the fresh food temperature is below 68°F (20°C), the fresh food defrost heater will be energized for 10 minutes. If the fresh food temperature is above 68°F (20°C), the heater will not come on.

During thermistor error operation, the control defaults to fresh food defrost every 5 hours and freezer defrost every 10 hours of accumulated compressor run time.

Fans

All 3 fans (condenser, freezer, and fresh food) are variable-speed DC fans. The speed of each fan is controlled by an algorithm in the power control board (PCB) and determined by many factors, such as room ambient, thermal load, temperature settings, number of door openings, etc. The fans are extremely QUIET, and determining fan speed is very difﬁ cult. As a general rule, if the voltage measured at the fan is within limits and airﬂ ow is felt through the vents, assume the fans are working correctly.

Note: The fans will run on a 9-volt battery for testing purposes. Use the two higher voltage pins as described in the following procedures.

Freezer Evaporator Fan

The freezer fan assembly is mounted directly to the freezer evaporator. The fan assembly (motor, blower and housing) is available as a separate part or complete and preassembled on a new freezer evaporator.

Operation of the freezer fan is also affected by room temperature. If the ambient thermistor senses a temperature of 82°F (28°C) or higher, the freezer fan will delay 5 minutes (after the compressor has started) before starting and circulating the freezer air. Below 82°F (28°C), the fan will start immediately with the compressor.

The freezer evaporator fan motor supply voltage can be checked at CN06 on the terminal block.

The fresh food evaporator fan motor supply voltage can be checked at CN05 on the terminal block. When the power control board (PCB) is energizing the fan, check for approximately 7 to 8 VDC between pin #2 and pin #6, and approximately 2 VDC between pin #2 and pin #5 at CN05.

Condenser Fan Assembly

Ambient temperature affects the operation of the condenser fan. If the room temperature is less than 45°F (7°C), the condenser fan will not run when the compressor is on. If the temperature is between 45°F (7°C) and 50°F (10°C), the fan will start 5 minutes after the compressor has started. Above 50°F (10°C) (or if the ambient thermistor is open or shorted), the condenser fan is synchronized with the compressor.
