In this video, I show how to replace a single pole contactor to a double pole contactor. This comes in handy for many air-conditioning repairs. The single pole contactor and double pole contactor have a always hot side. The always hot side always has voltage for the loads. The low side of the contactor only sends power, to loads. When the contactor coil gets energized. Therefore oh you have to do is connect all of your always hot loads to the back end of the contactor the L one side. On the other side of the contactor most the time one leg of power is broken by the switch. You can break both legs a power for your compressor. As an HVAC tech this is an important tip in case you do not have a single pole contactor.
