Everything seems to work fine, but the motor won't rotate. The power cord is good. I am thinking either a bad motor or a bad motor board. How can I narrow it down? Thanks

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,
