First, check that the safety key is correctly fitted.
Next, check for any loose cables or wiring inside the console.
If you need further assistance, please confirm the model number of the NordicTrack treadmill, and the approximate age.
Ok, that does seem to indicate that the left side cables may be loose - did you get a chance to check the cable connections inside the console?
If the cable connections seem good you will next need to test them for continuity in case there is a break in one of the cables.
If the cables all test good, then the buttons will need to be checked out next.
