  • Page 20 3.2 REFRIGERATION SYSTEM All refrigeration units cool by removing heat from the cabinet rather than pumping in cool air. In a conventional refrigeration unit, liquid refrigerant enters the evaporator and vaporizes (boils) due to the low pressure, creating a very cold surface which removes heat from inside the cabinet. This causes the refrigerant to boil (evaporate) into a vapor state and be drawn into the compressor.
  • Page 21 3.3 REFRIGERATION SYSTEM COMPONENTS Compressor The compressor is the "heart" of the refrigeration unit, consisting of an electrical motor and a "pump" sealed inside a steel case. The compressor used on R134A refrigerant systems is virtually the same in external appearance as the compressor used with R600a refrigerants. However, due to changes in lubricants and other internal differences, the compressors are not to be interchanged, otherwise system failure will result.

  • Page 23 that is connected to the discharging hose leading to the outside. When discharging the residual refrigerant, repeat 3 cycles that includes 3min of the pump running->pump off->30sec of the compressor running. After the refrigerant (R600a) is completely discharged, repair any defective parts and replace the filter dryer.
  • Page 24 3.5 SERVICE PRECAUTIONS FOR R134A SYSTEM LIMIT TIME OF EXPOSURE TO THE ATMOSPHERE Whenever a sealed system is repaired, do not expose an open line to the atmosphere for more than 15 minutes. Replacement components will come sealed by either brazing (filter drier) or plugs (compressor).
  • Page 25 too far into the drier and contacting the screen. To facilitate the installation, place a slight bend in the capillary tube about 3/4inch from the end and insert into the drier. Remove the process tube adapter from the condenser outlet and prepare the tube for connection to the drier inlet. The drier inlet joint will be the only copper-to-steel connection which will require the silver solder and flux.
  • Page 26 remain open throughout sweep procedure), open valve A to allow three (3) ounces of refrigerant into the system. Close valve A. Check low side for leaks. After system has equalized (about 3 to 5 minutes), start system compressor, check for high side leaks and allow refrigerant to circulate in the system about 5 minutes.
  • Page 27 accumulation of frost. Where possible, check the capillary tube and straighten any kinks to relieve the restrictions. Check the unit operation. If the condition persists, replace the defective part. If the freeze-up condition does not exist and there is not a kink, you can assume that a foreign particle is causing the restrictions.

  • Page 62  Remove the air duct cover.  Disconnect the PTC lead connector from the cable.  Connect the PTC heater to a rated power source on the rating label. If the PTC heater fails to operate, it is defective and must be replaced. 8.4.7 OVERLOAD PROTECTOR The overload protector prevents the compressor from burning out its electrical windings in the event the compressor becomes overheated or draws too much current.
  • Page 63 compressor, the PTC device's low resistance shorts out the run capacitor; thus producing adequate motor starting torque. As the compressor motor approaches run-ning speed, the current through the PTC device causes the temperature and resistance of the PTC device to increase to where it appears to be an open circuit.
  • Page 64 8.4.10 ABNORMAL NOISE / NORMAL NOISE Compressor Noise  The working of the electrical motor and the pump inside the compressor will cause noise during the run time. The noise should be stable and not exceed 42 dB(A). If the noise is excessive, the compressor is failed and should be replaced.
  • Page 65  The foams at the two sides of evaporator are lost or damaged. Replace the foams.  The temperature sensor is failed.  The compressor operates continuously & independent from the set temperature. At the same time the condenser fan motor does not operate. The POWER PCB has been failed and replace the POWER PCB.

Wrong connection of thermistor for left/upper zone and right/lower zone. 8.4.20 DSIPLAY “E7” “E7” indicates the door switch failure. It may be caused by the following reasons: The door is not closed properly. Pls open and close the door with a little more force. The door switch is defective.
  • Page 68 8.5.7 The appliance never seems to stop: the unit is always on. Make sure the door is closed properly. Add a separate thermometer inside the cellar to see if the cellar thermostat indicates the same temperature. If the results are different, replace the thermistor or Control PCB or Main PCB.
