Hi, so I have this small Sunny Health treadmill that suddenly stops as I was walking on it. The panel is still on and everything to indicate that it is running, but the motor will not spin. I tried turning it off and on, press the surge reset button to no avails. When I plug in the key and start the machine all I hear is a click and the motor will just lie there silently. I can see the light on the control board lights up. The control panel works. Everything is functional except the motor will not spin. I think it may be the control board but I don't know how to rule it out step by step and if it is whether i can find another board to replace it, or if it is worth it to fix at all. I have limited electrical knowledge so please bear with me. Many thanks!
