Freezer room and Refrigerator don't cool. Flowing sound of Refrigerant is not heard and frost isn't formed. Cooling operation stops periodically, Flowing sound of Refrigerant is not heard and frost melts, o COMPO _ RESSION :um rnQ 03-4 __ O rn Z NO COMPRESSION Freezer and Refrigerator don't cool. No compressing operation, Low flowing sound of Refrigerant is heard and frost forms in inlet only. Flowing sound of Refrigerant is not heard and no frost, TEMPERATURE OF THE COMPRESSOR A little high more than ambient temperature, Equal to ambient temperature. A little high more than ambient temperature. Equal to ambient temperature. Low than ambient temperature A little high than ambient temperature, Equal to ambient temperature, REMARKS • A little Refrigerant discharges. • Normal cooling is possible when injecting of Refrigerant the regular amount. • No discharging of Refrigerant. • Normal cooling is possible when injecting ef Refrigerant the regular amount. • Normal discharging of refrigerant, • The capillary tube is faulty. • Normal discharging of Refrigerant. • Cooling operation restarts when heating the inlet of capillary tube. • The pressure of high pressure part in compressor is low. • No pressure of high pressure part in the compressor. • Leakage Detection • Observe discharging point of refrigerant which may be in the oil discharging part in the compressor and hole of evaporator. Whether Compressor runs or not, Whether frost YES forms or not in Evaporator. Frost formed normally Normal amount No frost or forms in inlet only > Wleahkestheorr nooilt. | Observe the discharged amount of Refrigerant. Moisture Clog. Faulty Compressor.
