    Condenser fan motor replacement
    I have a Rheem heat pump and have purchased a replacement condenser fan motor. It had an Emerson KA55HXPAM-7255 and was crossed over to an A O Smith ORM 1008. My problem is the wiring, the new motor has one more wire than the old one. I had orange, brown, black on the old one. The new one has Brown, Brown w/ white stripe, black, and yellow. According to cross references this motor is a replacement, but I'm not sure what to do with the extra wire.
    There is also a slight hp and amperage difference. HP went from 1/10 to new one with 1/6 and the amp went from .75 to 1.1. Will this be a problem?

    Answer is simple. The two brown wires go to the fan motor capacitor and the other two wires go to each side of the 220/240 volt contactor. Lower left side diagram. Instead of white make it yellow since the diagram is generic.

    Brown, Brown w/ white stripe go to cap, black, and yellow get the voltage.
