Also, read c. sensible Electrical pressure 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 order for a PTC relay's resistance to drop low enough for a motor to start again, it must have enough time to cool down. Carefully disconnect the wires with a pair of pliers, and then remove the relay by pulling it off of the prongs on the compressor. 12,000 b.
