Hi, There are two possibilities for this problem 1. Check the speed sensor on near the motor pulley. Remove the sensor and clean it and re-fix it. then make a try. if problem remains then 2. The motor speed controller is faulty. There is an IGBT for controlling the motor speed. If it get shorted the motor will run it its correct speed.
Be sure before opening the treadmill remove the power. ok
