Enter calibration mode and do a calibration first.
Press the stop & speed up key, insert the safety key/magnet. Press stop 1 more time. Press speed up, the speed display should start to increase in value. By 30-40, the motor should be running. If not, you either need a motor or motor controller PCB. What model is the treadmill?? PCTL???
