NordicTrack Adventurer NTHK9990 incline stuck

SOURCE: nordictrack apex4100i level incline will not work

Try this calibration procedure.
Turn the power switch on. Remove the safety key. Hold the Stop and Speed Up or Speed Plus buttons down then insert the safety key.
The display should show some numbers.
Press the stop key one time and the display should show some other numbers and some 00's. Press the Incline Up button and see if the Incline begins to move, if it does let it go all the way up and then all the way down, wait a few seconds after it stops, then hit the stop key 4 times. It should be calibrated. If it didn't move then the board or the incline motor is bad.

it is trying to calibrate itself, let it go the whole way up and then down without interrupting it. Then it should be fine.
