This unit came with a combined capacitor and a start capacitor. If I am reading what you are saying right, you are saying that I need to leave those two there and add a third capacitor that came in the kit?

In a word, YES. The new single-value, two-terminal capacitor that came with the new fan motor replaces EITHER:

1. A single Fan Run Capacitor (in which case there are already three capacitors on the unit: Single Fan Run, Single Compressor Run, Compressor Start)

or

2. One side of a Dual (two in one) Fan Run + Compressor Run capacitor (in which there will be three capacitors: The NEW Single Fan Run, Original Dual Capacitor with only HERM connected, Compressor Start)

In Case 2. the COM terminal of the Dual Capacitor has to be connected to either terminal of the new Single Fan Run Capacitor and the Fan capacitor wires to both terminals of the new capacitor.

You can try using the original Dual Capacitor and hope that the Fan Run side was not the cause of the fan not running. I put a new fan motor in our Coleman Mach. It didn't come with a Capacitor. The new motor runs fine with the original, 14-year-old capacitor. But, two things:

1. I have a meter that can test capacitors and ours tested OK on both sides, Fan and Herm.

2. Our original motor was replaced because of Bearings, not its Windings.

In passing, I still have that Coleman motor. If somebody can use it to salvage one with good bearings that failed electrically, let me know.

OK sorry, but I am going to appear extremely thick and I do not mean to, but I just do not understand.

My unit originally had two capacitors. One of them said Motor Starting which was skinny and small and had only two poles on it. Before I disassembled the red wire from the motor starting capacitor went to the Herm side of the three pole capacitor. The white wire from the motor starter capacitor wen to the common on the three pole capacitor. I have attached a photo and I hope it comes through.

Now what I am trying to understand is are you saying that I am going to have three capacitors up there? If so, how should they be connected?

OK I have it hooked up this way:

Only connection to dual capacitor is herm.
All other connectors going to new capacitor that came in the kit.

Right now the only thing that attemps to fire up is the compressor and I actually hear it filling up with freon.

When I just switch on fan, nothing happens. I hear a click in the ceiling, but that is it. Never starts.

Earlier in the day when I had the problem with the wiring harness order, I clearly remember that both the compressor and the fan motor did turn on independently, just not at the same time as normal. So I know they both work.

I took my capacitors, all of them, and tested them. Both are showing infinity.

Any ideas?
