Treadmill won't slow down

After I have set a speed and want to slow it down it does nothing and I'm not certain the incline works, you hear a noise as If it's changing but doesn't feel like your walking uphill. Also sometimes when turn on it auto sets to run for 90minutes. What could be wrong?

    Set the speed to 2.5 MPH. Let the treadmill run without anyone on the belt. Check to see if the speed is constant or if there is a variation.
    If there is no variation, step on the belt. If the speed slows down or speeds up, you may have an output problem on the DC board. This is the board that connects directly to the motor.

    The speed is constant with or without someone on it

    Sounds like a short circuit console issue, can you unplug the ribbon cable that goes from buttons to main console and clean the ends real good then plug back in and see if that helps?

    If that does not help - make sure there is no crimping in the wires...

    It could be that the lower board is not sending voltage to the console and the only way to know this is if you have a voltmeter and can test the red wire & the black wire.

    You should have anywhere from 8vdc to 12vdc on those two wires.
    If you have that voltage then the console is bad.
    If you do not have the voltage then the motor controller is bad
