    Trane XE 1200 Heat Pump - Condenser Fan Motor Replacement

    I am trying to replace a fan motor on a Trane XE 1200 heat pump condenser. It decided to wait until I was laid off from my job to break on me, so I really can not afford to have someone come out and do it for me. I usually repair things on my own when they break in my house, so I am very familiar with DIY. However, I have never had to replace a fan motor on my AC system before. The only part I'm not sure about is the wiring. The new motor has 4 wires. The wiring diagram shows to put the brown and brown/white to the capacitor. And to put the white wire and black wire to LINE.

    However, my system does not have any type of schematic\wiring diagram. I have attached a picture of the wiring in hopes that someone could help shed some light on where to connect the wires for the new fan motor. The old motor was a 3 wire system, this new one is 4. I labeled different parts with letters to make it easier to identify\discuss parts if that helps. "A" is the capacitor. I'm not even sure what "D" is. Another capacitor? If so, what for? "C" is the defrost board and "B" is the contactor. "E" looks to be a relay, but I'm not sure what that is for either.

    By looking at the picture, does could anyone shed some light as to how this thing is wired and where to wire the fan motor connections to? I've been running on AUX heat and it's making my electric bill jump, as was expected. I don't have the cash to have someone come out so I have no choice but to do it myself. I just need a bit of guidance on this part.

    Thanks!

    Its best to get a new capacitor for the motor only and not use the dual run cap for the new motor,after you finish the motor clean the condenser coil !

    I see your motor problem. You have a wire disconnected.

    Maybe call your local Trane dealer and get a wiring diagram for your unit?
