To answer your question your question about the sensor, it is magnetic and a small magnet is located on the flywheel. I was able to verify the sensor is picking up the magnet movement.The best way for trouble shooting these models is to power up and test each independently, IOW, both console and the motor board each have a micro-processor, the motor board can easily be tested on the bench but needs a 20Hz PWM signal plugged into HD2 in order to vary the speed.
Strange if it shows the track is moving as this is usually a sensor on the belt?
Thank you it has been so long since I have looked a schematic I forgot how good it was to "read" one.Post #39 for the reverse-engineered schematic, keep in mind that there is at least 5 ver of the board so this is just a general guide.

Yes the one on the control board.I failed to add that the reed switch for the belt is working but no signal indicated on the LED.
¡De nada! :Rodar los ojos:

Hola Max, tengo mi caminadora con un controlador dañado (STR G5551). ¿Existe alguno similar que pueda servir como sustituto?
