how can i get my treadmill to work?

Can I fix my BT 3120 motorised treadmill computer. The speed option on the computer will not work. It allows you to set the other options, calories, km, etc, but not speed. Can you help

You may have a bad lower board. We need to try a test.

Stand on the side of you treadmill and push the belt with one foot.
Push the start button and keep pushing the belt..
If your treadmill belt starts to run, you may have bad motor brushes caused by a dirty or worn belt and deck.

If it doesn’t start but the speed is being read then you could have a bad lower board.
A loose motor wire could do this too. For further help You can contact me here,
