Treadmill beaker goes off

I have a proform 770ekg. It come on and it runs for maybe 5min the the breaker trips.


  • You have a short either in the motor controller or drive motor, unplug the drive motor from lower board and then see what happens. if breaker still trips you have a bad motor controller. If it does not thrip then you have a short in motor.
  • I don’t know how to do that
  • Just take hood cover off treadmill and you will see the large drive motor and you will see a black wire & red wire going from motor to lower board, unplug those two wires.
  • It doesn’t trip. It only trips when the motor is running and I get on it. It runs fine if nobody it’s on it
