    Hayward (EUS) fan motor wiring

    Need to replace a fan motor in a Hayward/EUS heat pump. Unfortunately, the old motor has 4 wires (+ green) coming out of it while manufacturer specified new motor has only 3 wires (+ green)

    Stupid upside down picture; photobucket having some, uh, issues apparently.

    Regardless, any idea(s)...Tech Support for product has been, uh, a bit lacking. And nobody seems to have wiring diagrams to identify old/vs new wiring. Heat pumps...argh!!!!

    New Motor:


    Old Motor:

    Does the new motor have a wiring diagram on it like the old motor does? If it does post it.

    Can you get a clearer pic of the old motor wiring diagram? At least tell me what the colors are on the diagram. I think I can make out Black and maybe Yellow. I could guess the other two but I don't like guessing.

    New motor on left, old motor on right:


    Can't even find a telephone # for EUS (that works, anyway)

    And that's all we need!

    Power goes on red and yellow instead of black and red
    And the cap that was between brown and yellow still goes between brown and yellow.

    On the new motor, red goes to red, yellow goes to black and yellow, and brown goes brown.

    Gonna give it a shot, thanks for the info. A question for the electrically ignorant: What is SEP. CAP.? Is that a start capacitor or something similar?

    Thanks again...great place.
