Your board should light up with red ,green, or amber L E Ds now manually move the running belt and you should see one of those lights flickers that should tell us the speed sensor is working, if not it needs to be replaced , their maybe other issues, Unplug unit then find the red and black wire that connects the motor to board disconnect them used a simple DC power source like a 9v battery connect them to the motor leads and if the motor armature rotates then all problems point to the motor controll board.
