You have to check the Driver circuit board for the motor. There is motor control IGBT Insulated Gate Bipolar Transistor) in this board .If the IGBT is short then the treadmill will not run or will run at high speed. . You have to check the OHMS between the seocnd and third of lead of the IGBT. If it shows less than 100 Ohms then the IGBT is short and you have to replace the same. Also you have to check the connection to the control pannel. Is there is any loose conatct. Remove the connection in the motor control board which go to the control pannel and reconnect it. Also check the speed sensor. In most of the treadmill you can find the speed sensor near the motor pully. Remove the speed sensor and clean it and the refix it. Remember one thing remove the power of the treadmill and leave it for 30 minutes then only oppen the treadmill. Because there is high voltage storage capacitors in the motor control board which will hold charge for some time even after the power is disconnected. i have added the picture of IGBT for your refference
