Are you familiar with the contactor?
The contactor has the high voltage wires coming in on one end and then when closed sends it out the other side.
On the new motor we want black to one side and white beside it on other side...then 2 browns to new capacitor...and no other wires to the fan capacitor...
2 wires to the contactor and 2 wires to capacitor.
The old motor black does (did) go to the contactor. You will ee this part has 2 feeds in and 2 feeds out.
So black to where it was, white on the pole beside it. Then the 2 browns to the NEW capacitor with no jumper. Leave all the rest of the wires where they were as far as compressor and other capacitors.
Great. found the contactor. Sound easy from here on out. Ok. It's getting late and I am out of daylight. Plus the white and black wires on the new motor do not have the clips on them for the poles. Too late to run to Lowes. They are already closed. So, can we finish this transaction tomorrow when I have the unit up and running? I may need to ask you more questions.
This repair started with a sheared fan blade. The old original motor is still kicking. But, I couldn't get the orignial fan hub off of the shaft. It was rusted on. So, thus the new motor. New capacitor and 5 bladed fan for more efficiency. Thought this would be a 2 hour job at most. But, not sure on all the wires. Thanks for your help.
The contactor has a bunch of poles on it. The black wire from the old motor is plugged into the "L" side of the contactor which I assume is the left side. There are other black and blue wires on the "R" side of the contactor. Ok, almost there.Do I plug the white motor wire intot the R or L side. I would think the wire would go opposite the black which is in the L side. Thus, the white goes into the R side. But not sure. There are literally, 13 different posts there on the contactor. R or L for the white wire?
You are correct..opposite of black.
white r and black l
sounds like the white and black are on the wrong end of the contactor.
The black wire is in the same place it was when the old motor was in. I just switched the black and white wires. Had the same result. The fan is still going on but off when the compressor kicks on. Back on when the compressor is turned off.
I am going to try and send you a photo of the contactor. The motor black wire will be on the bottom (L). The motor white wire will be on the top (R). The white is wire nutted to a yellow wire I stole off of the old motor. It had a clip on it. Shouldn't make a difference. But I thought I would tell you if you notice the white wire is actually yellow. I headed outside to take a photo now. Back in a few. . .
The picture would be great....
Ok I see the issue. This is a one pole contactor instead 2 pole contactor. This makes one line always hot.
Do you see where the main 2 power wires come into the ac unit? and only one goes to the contactor?
That is where the white goes.
This is an older style using a one pole switch instead of 2....this means one hot comes in direct without going to the contactor (switch).
Leave black where it is and attach white to the other main coming in.
Correct. Wire nut white to the bundle.
Now you have 2 hots coming in....the black goes to the contactor and the other feeds the compressor, capacitor and motor direct from bundle.
let me know if this does it.
Eureka! Works like it should. Cold air is coming out the vents.
Thanks for all your help. All my paper instructions referred to a two post system. Thus the confusion. Thanks for hanging with me on this one. Definately worth the money.

I am very glad you had the patience to see this out. I was not picturing a 0ne pole contactor. Sorry for dragging it out.
