    Yes, I agree with Rick, sounds like your control board is possibly the culprit. Yes, you have to transfer the jumper wire from the old control board to the new control board in the exact same place it was on the old control board.

    You can actually test your control board.

    Communication voltages are sent from the Control Board to the Motor. Test for these steady and pulsing serial voltages at the Control Board J7 Connecter.
    Check for approximately 12.8 Volts DC steady from RED to BLUE. The BLUE wire is DC ground.
    Check for the pulsing DC communication voltage from the RED and YELLOW. This is a pulsing, not a steady, voltage. If either voltage is absent at the Control Board J7 Connecter, replace the Control Board.

    Here's the control board for THIS model:
    WH12X10614 Control Asm


    If the steady and pulsing voltages are OK at the Control Board J7 Connecter, disconnect the communication harness at the Motor and check the Motor harness connecter for the same voltages found at the Control Board.
    If voltages are OK at the Motor harness connecter, replace the Motor.

    Here's the motor for THIS model:
    WH20X10094 Motor and Inverter Asm
