Found you folks because of the Supco SPP6E mod on your site. Here's where I am ….

I have a Carrier 15000btu A/C ducted unit. It came with a 45mfd/12mfd dual-value capacitor, wired like this

Common junction - 3 white wires, 2 red wires (one of the red goes to a PTC)

Fan junction - 1 brown wire

Herm junction - 2 blue wires (one to the PTC)

I bought the SPP6E and a 12mfd run capacitor (the run cap only has two junctions), because Carrier quit making my air conditioner and I can't find the original dual-purpose cap anywhere.

I had no problem cross-wiring from the single dual-purpose cap to the two caps until I realized I'm not sure what to do with the brown fan motor wire.

Assuming (and all that it implies) I use one side of the run cap for common and the other side for the blue compressor wire, do I also put the brown fan motor wire on the same junction as the compressor wire, or do I need to go back to the parts place and get a three-junction run capacitor …. or have I looked at this all wrong in the first place?

Any advice would help … thanks, john

Can you use a spp8e on a duo therm 15000 watt ac, or is it to much ?
