    Trane Odyssey Heat Pump

    After troubleshooting and finding a bad board and to verify I exchanged boards with a running unit and Condenser started up then after a few days unit stopped working. I did get a new board and still same problem. I have 24 volts to terminals on new board and I have checked High and Low pressure switches and getting continuity. I also have checked relays and continuity on normally closed. I do have high Voltage on terminal coming from disconnect to unit. Anything else anyone could suggest I check?
