The marked terminal of a run capacitor should always be connected to the ________side of the circuit. the widow's son in the windshield continuation which is a part of the kit may be good to re-use or it may not be good to re-use. 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. In Fig. All of the above. c. relay Bye what is ptc heating element, That is really nice to hear. Required in the start winding to energize a potential relay coil.
