NordicTrack Treadmill T9si
Wondered if anyone had advice that could help. My treadmill shuts off (I think safety thing) when I press start. I had assumed it was the motor after testing so got another one. Same issue. If I unplugged the speed wire, it does not shut off. But also does not turn either as it relies on speed. So makes me think something to do with the speed cable or board (not sure it's the cable as I have tried with 2 on the motors). Don't really want to buy a board if it's not that as already spent money on a motor that I can't get back (bought off eBay).
