Probably 85% of the time, it's the sensor.
1. remove the screws from the bottom of the enclosure case. 2 or 3 in the front and 1 on each side
lay it back down, and power it up, and actuate your incline. watch the end of the motor, to see if the shaft is moving. It probably IS turning but only a little bit. NOT enough. In this case I'd say it is the sensor.
2. Unplug the unit of course.
3. the incline motor is in the middle of the pack,..you'll see a black tube looking thing sticking up.
4. on the bottom side of this, you will see,..or feel for a black square sensor attached to bottom of the motor casing.
5. follow the wires and unplug this.
6. pry it off with a screw driver. Remove incline assembly, if you cannot reach it.
7. replace sensor and try it again.
if the MOTOR does NOT turn when using the incline buttons, the problem backs up to possibly a bad control board. or a bad motor on your incliner, however, i'd say that's the last thing to go.
Order of failure: 1. sensor 2. control board 3. motor.

Check the drive belt. It may be loose or broken. If the belt is loose, then to tighten the drive belt, start by removing the front cover. loosen the bolts around the motor then tighten the drive belt by tightening the motor adjuster bolt. Once the drive belt is tight, tighten the motor back down.

If the incline moves but only just a bit, it could be a problem as simple as the gearbox on the motor being jammed. We remove the motor from the treadmill, reconnect the wiring, and then try to run the incline motor outside the treadmill. Many times, this will unjam it if that is the problem and then reinstalling it in the treadmill will get it to work. If you have the same problem or it doesn’t run outside the machine and you can hear it try to work, you need to replace the incline motor.

I have the same unit. First, remove the hood. Then, the motor has an adjustment screw on the belt side of the motor. Loosen the nut a little, adjust the motor up or down to make the belt as tight as you can by hand, then re-tighten the nut. This always fixes mine.
