If your Reebok Jet 200 treadmill is stuck at an incline and you are unable to lower the incline to the 0 position, there are a few things you can try to fix the problem:

1. Check the incline motor and make sure that it is properly installed and functioning. If the motor is damaged or not functioning properly, it may be causing the incline to remain stuck.
2. Check the incline control board and make sure that it is properly connected to the incline motor and other treadmill components. If the control board is damaged or not functioning properly, it may be causing the incline to remain stuck.
3. Check the incline cable and make sure that it is not frayed or damaged. If the cable is damaged, it may be causing the incline to remain stuck.
4. Check the treadmill's belt and make sure that it is properly aligned and tightened. If the belt is misaligned or loose, it may be causing the incline to remain stuck.
5. Check the treadmill's power supply and make sure that it is properly connected and functioning. If the power supply is not functioning properly, it may be causing the incline to remain stuck.

If you have tried all of these steps and are still having issues with the incline on your Reebok Jet 200 treadmill remaining stuck, you may want to consult a professional for further assistance. A treadmill repair technician will be able to diagnose the problem and recommend the best course of action to fix it.

Hold down the "Stop" button and the "Speed" up button. Insert the safety key into the console then release the "Stop" and "Speed" buttons. Press the "Stop" button then press either the "Incline" up or down button. Wait while the treadmill raises then lowers the incline ramp.

This sounds like the treadmill is running an incline calibration. It will run to fully inclined, then to minimum incline.
It should not do this every time you want to operate the machine, but they will do it automatically if the operation of the machine is stopped by the power being interrupted..

My wife had the same problem with her treadmill. I turned the beast on it's side, and unscrewed the plastic casing that houses the motor, computer, and all the electronics to the treadmill. I unplugged the incline/decline motor. Then on the bottom of the treadmill the long threaded rod that causes the incline needed to be moved. So I unbolted it from the catch, and manually screwed the rod back in with a wrench. Now the treadmill works fantastically, of course the incline/decline mechanism has been disabled, but I would rather have a treadmill with the incline disabled than have one always on 100% incline. Hope you found this helpful :)

Open the motor cover. There should be a service sheet in there.
Read Option 2 & try it.
