I have been having problems getting my condensing unit to fire up and the fan I ask earlier and got a response I have 24 volts coming in and I do have 220/240 also but it still will not start?? is their a low or high pressure shut off switch?? I also bought a new thermostat and the new one had a different wiring diagram as follows E,Aux,Y,G,O,L,R,B,C, the wires coming to unit are as follows,Brown,white,yellow,green,orange,red,light blue,where would the white go?? Is it the AUX? Is brown the E, And blue the B, or C?? Not really sure thanks

You will need to go to the air handler and remove the access panel to see what wires go where , the white will probably go to Aux. heat, the other wires may go to the outside unit and you will have to see what goes where on the terminal board out side. Good luck.
