If the incline is stuck, it could be a problem as simple as the gearbox on the motor being jammed. Unplug the treadmill remove the motor shroud then remove the incline motor from the treadmill, reconnect the wiring, plug in the treadmill 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.
If the incline motor does not move, we need to figure out if the motor is getting voltage. Use a simple multi-meter and set it to AC volts. When you put it into calibration, it tries to calibrate the directions one at a time. Measure across the white and black wires first, then measure across the white and red wires second. If the motor is getting voltage you will read 120VAC (or thereabouts) one one of the measurements. If you have voltage but the motor won't move, you need to replace the motor. . If the incline motor does not move and you have done the voltage test and you do not have any voltage present, there is a problem in the electronics board that supplies the power, you need to replace the board.

try thisSometimes incline motors will get frozen in position and need broke free. Try this:
take the motor cover off and take the screw out of the bottom of the incline motor that is attached to the screw assembly. Once you remove the screw you should be able to break the incline motor free. run the incline up and down with the screw still off( laying the treadmill on its side may make this easier). Once it goes up and down (hold the screw so it goes in and out) reattach it then run the calibration described below. If it was just stuck it should work fine.
1. remove safety key
2. press and hold the speed+ and stop keys at the same time
3. Put the safety key in/on and release the keys
4. press stop once
5. hit the incline + arrow and let the incline go the whole way up and down
6. remove safety key and try
If these instructions do not work to fix the incline motor
check your main harness running down the right leg for breaks in the wires or a loose connection if nothings found you can switch the red and black wires on the incline motor terminal block and see if it goes down. If it does you know you are only getting voltage to one side of the motor. There is a schematic under the motor hood that tells you what the voltage should be when you press the up or down keys. Use a multi-meter to see if you are getting the correct voltage coming from the console to the motor control board and then from the board to the motor. If no voltage from console-replace console if you have voltage from console but not from board - replace board and finally if you have voltage from console and from board replace motor. You will need to test the voltage both when pressing the up key and the down key.

Although it is fairly rare the incline motor can jam up into the highest position and get stuck there. To fix this take off the plastic hood that covers the incline motor and depending on the motor you should be able to wind it with your hand out of the highest position. When it is out of the highest position run the calibration as described in the owner's manual and it should go all the way up and all the way down. If it is not this type of motor that can be wound by hand then the first and last thing to do is to try calibration of the incline as described in your manual. If this does not work then a new incline motor is needed.

SOURCE: lower incline
I STRONG recommend RUN the calibration Software Inmediately, for eay Diagnose and troubleshooting, most of them instruction has coming in the Hood of Motor, follow the instruction or use your instruction manual.
Adjust the sensor speed attached the diagram. Tight the wires from sensor speed. The sensor speed can be faulty. Adjust the Pot with the gear in the same motor, both can be faulty. And finally the main motor board can be wrong. sincerely.
God bless you.
