Question about Heating & Cooling
Hi, the 2 - brown wires are for there own run capacitor they should have sold you. One of the browns will have a white stripe. The new cap has only 2- terminals and you put a brown on each side. The black and yellow wires are both hot which 1- will go to 120 volts on the load or out side of the contactor, and the same with yellow, 120 volts. This gives you 220 volts to run the motor. Look on the new motor and you will have a diagram or on a paper that comes in the box. The old motor used the dual cap to run the compressor to. The green is just a ground wire. Screw it to any metal part or screw. You should be able to put the black and yellow hot wires where the old black, red, or blue were as long as they are 120 volts which I am sure they are. Get a cheap tester when you go get the cap for the new motor, and check the old blk, red, and blue terminals to ground and you should have 120 volts on at least 2 of them. Put the new yellow to 1 and black to another, browns to the new cap and your off and running. Keep me posted. I do this everyday. Please be kind when rating me, thank you.
