In the PTC relay the supply goes direct to the run winding but between the supply and start winding a thermistor is connected in series and when we switch on the refrigerator the current start flowing through the thermistor to the auxiliary and compressor start-up, this current flows heat thermistor and due to temperature, the resistance of thermistor high and thermistor remove the start winding from the supply. a. In many cases, we connect a capacitor that works and works in the relay for which it aids in the suction of the compressor.
