I have the norditrac c2150. The machine won't do anything but incline the decline then go thru process all over again. It will not respond to any keys. Unplugging it doesn't fix it. Is there a reset button or how can I fix

Method 1: Press Stop and Speed Up, Insert the Key
To calibrate the incline, press and hold the stop and speed increase buttons. While holding the buttons, insert the safety key. The machine will now be in calibration mode. Press the Stop button once. Then, press one of the incline buttons to begin the calibration. It is recommended that you do not stand on the machine while the calibration is taking place.
The machine will move to its highest incline position, then to its lowest decline position. Please wait for the machine to come to a complete stop. When the machine stops moving, the calibration is complete. Remove the safety key from the console to exit calibration mode.
Method 2: Press the Stop Button, Insert the Key
To calibrate the incline, press and hold the stop button. While holding the button, insert the safety key into the console. The machine will now be in calibration mode. Press the stop button once. Then, press either the incline up or incline down button to begin the calibration. It is recommended that you do not stand on the machine while the calibration is taking place.
The machine will move to its highest incline position, then to its lowest decline position. Please wait for the machine to come to a complete stop. When the machine stops moving, the calibration is complete. Remove the safety key from the console to exit calibration mode.

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.

Without insulting you, I assume that you have waited long enough for the incline calibration to complete (while standing on the treadmill, say one or two minutes). I also assume that you would agree that moving the machine has somehow caused it to malfunction. Check that the new location is reasonably level and that all four "feet" touch and rest on the floor. If nothing remedies, it may be time to call a technician.

Check the end sensing switch on both side.

Bad contact in the switch

get a new battery

LUBE the rack and gear very well. Adjust the POT small attached, and try again. However you must see the diagram attached Tight any wires and connector very well and clean .Will be a good idea RUN again the software calibratin after you did the adjustment, clean and lube.God bless you

I have a Proform ZT5 model - had the same incline/decline problem. It needed calibrated.
- unplug, turn off, and take the key out
- plug machine in
- turn switch on
- Pres and hold the STOP and SPEED UP button at the same time, while holding them insert the RED KEY
- let go of both buttons
- press STOP 1 time
- pres INCLINE UP 1 time
- this should reset it.

The tech on the phone mentioned the importance of turning the maching off, taking the key out, and unplugging after each use. Leaving it plugged in there is still an electrical current running and this can cause more seriouc problems that require a new control panel.

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..
