  • Page 10 7-3.Relay Inspection method Operating principle The relay momentarily energizes the start winding to start the rotation of the compressor motor. Most later refrigerator models use a solid state type relay. Unlike the mechanical type relay, the solid state relay has no coil and no moving contacts. This relay consists of a small solid state wafer that has a low resistance at room temperature.

    8.HOW TO REPLACE MAJOR COMPONENTS 8-1. REFRIGERATION CYCLE COMPRESSOR: In evaporator liquid refrigerant is so expanded to absorb heat around evaporator that compressor sucts refrigerant in low temperature and low pressure and then compresses it to gaseous refrigerant in high temperature and high pressure which will be discharged to outside. Gaseous refrigerant in high temperature and in high pressure so radiates evaporation latent heat CONDENSER: absorbed from evaporator surrounding during passing through condenser and compression heat...
