  • Page 8: Principals Of Refrigeration

    Principals of Refrigeration Phases of Refrigeration The compressor is the heart of any refrigeration system. It serves as a pump to circulate the refrigerant and create pressure within the system. When the compressor is operating, one side of the system is at high pressure and the other side is at low pressure.

  • Page 10: Dryer

    Dryer The refrigeration system must be free from dirt and moisture. A single particle of dirt, or one drop SUCTION TUBE of water, can cause the system to fail. For this reason, a dryer is a necessary component of the refrigeration system.

  • Page 11: Capillary

    Capillary The capillary is a very small diameter tube that is about 6 to 8 feet long. Its primary function is to control the flow of refrigerant into the evaporator. SUCTION TUBE The flow rate of a capillary is determined by its diameter and is critical to the proper operation of the refrigeration system.

  • Page 12: Refrigeration System

    Refrigeration System The refrigeration system has several new components as well as several familiar ones. New components include: • Inverter compressor • Inverter • 3-speed condenser fan • Accumulator at the outlet of the evaporator Familiar components include: EVAPORATOR FAN •...

  • Page 13: System Pressure

    An accumulator has been installed at the outlet of the evaporator to prevent liquid refrigerant (low quality) from entering the suction line. Changes in compressor speed (transition state) can Accumulator temporarily reduce refrigerant quality. The accumulator compensates for this by collecting and holding up to 2 oz of liquid while allowing vapor to pass.

  • Page 14: Inverter Compressor

    Inverter Compressor The new inverter compressor is not controlled by 120 VAC output from the main control board, as in previous models. The compressor is controlled by the inverter. 6-PIN CONNECTOR Warning: Disconnecting the 6-pin connector does not disconnect power (120 VAC) from the inverter.
  • Page 15 High compressor torque enables the compressor to start against high pressure in the sealed system. When power has been disconnected from an operating unit, the high torque will enable the compressor to start immediately upon power restoration. Compressor and sealed system operation is extremely smooth and cool. The compressor exterior may be room temperature while operating;...

  • Page 16: Inverter

    Inverter Warning: Disconnecting the 6-pin connector does not disconnect power (120 VAC) from the inverter. The refrigerator must be unplugged before servicing the inverter. Note: Certain voltmeters will not be able to read voltage output from the inverter. If no voltage or erratic voltage is measured, it does not necessarily indicate a faulty inverter.
  • Page 17 Note: When servicing the inverter, it is important to dress the wiring to keep low-voltage DC wiring and 120 VAC wiring separate. To remove the inverter: 1. Unplug the unit. 2. Remove the rear access cover. 3. Remove the screw securing the water valve and position to access the inverter.

  • Page 18: Adaptive Defrost

    Adaptive Defrost Adaptive Defrost Adaptive Defrost (Pre-Chill Operation) When the main control board determines that Adaptive Defrost can be described as a defrost defrost is necessary, it will force the refrigerator system that adapts to a refrigerator’s surrounding into a continuous cool mode (pre-chill). During pre- environment and household usage.

  • Page 20: Fans

    Fans Evaporator Fan The position of the fan blade in relation to the shroud is important. Refer to illustration for specifications. 5/16" ± 0.03 Blade tip 1.0" ± 0.05 Target Orifice Air Flow Motor GEA01149 The evaporator fan is the same fan used on previous models; however a significant difference is that the main control board does not require, nor receive, input from the fan feedback/rpm (blue) wire.
  • Page 21 The evaporator fan has a 4-wire connection: White Wire (DC Common) The white wire is the DC common wire used for testing. During repairs, DC polarity must be observed. Reversing the DC polarity will cause a shorted motor and/or board. Red Wire (Supply) Each motor uses an internal electronic controller to operate the motor.

  • Page 22: Condenser Fan

    Condenser Fan The fan is mounted in the machine compartment with the No-Clean condenser. The fan and fan shroud are mounted on one end of the condenser, and the other end of the condenser is blocked. When the fan is operating, air is pulled from the center of the condenser, drawing air in through the coils.

  • Page 23: Fresh Food Fan

    One complete revolution of the motor is comprised of all 4 poles. To determine the rpm of the fan, do the following: Measure the frequency being applied to the motor. Multiply this number by 15 (60 seconds divided by 4 poles). For example, a frequency measurement of 200 Hz multiplied by 15 would show a fan speed of 3000 rpm (15 x 200 = 3000).
