    When I turn on the treadmill the motor takes off(too fast)for just a
    second then shuts off.The control console says "motor controller
    error"

    PLEASE HELP!

    Not enough information. Make? Model?

    I suspect that the MOSFET (?) drivers in your treadmill controller are
    shorted, or perhaps the tacho feedback has failed. In any case, your
    post indicates that you probably do not have the requisite expertise
    to effect a repair.

    Contact the manufacture of the unit and order a new board that has the
    motor controller on it. Those are board level repair and very few
    treadmill makers have component level schematics available.

    manufacturer,National Gym Part and Sportssmith they
    all say that they do not work on a board this old.A
    new one is about $350.I buy and sell used fitness
    equipment,this comes up all the time and I need to
    learn to fix problems such as this that are common to
    treadmill controllers.I paid $5 for this unit either I
    will fix it or it will go to the dump.It is a Precor
    9.1.I had parts off a Precore 9.2 that I paid $8
    for.The 9.1 would not do nothing at first.I noticed
    where the circuit trace had melted right where the AC
    power entered the board so I fixed that and took the
    rectifier(I think)off the 9.2 board and exchanged it
    for the one on the 9.1 board.Now it starts up and runs
    for a second like I said then stops
