So we have a Proform 590Qs treadmill that when we plug it in starts to incline on it's own and the decline button does not work. We've tried the reset and even opened the cover to the board and pulled the cable for incline up and manually pushed it down which temporarily fixed it but when we plugged it in the treadmill would not roll. Maybe the incline up wire needs to be attached for that but anyone have any idea on what to check to fix the decline function?
