Incline motor on incline trainer moves but will not go the full range motion.

The motor may not be calibrated with the console due to the console not receiving a signal from the incline sensor. First calibrate the machine. If incline calibration doesn't fix the issue, and the incline only moved up a little ways then down a little ways during calibration, then replace the incline sensor on the unit (models NTL15008 & 24816 only).
