SOURCE: Calibration Mode for nordic track treadmill model
Hello there, The calibration mode for a nordictrack is as follows.
With the safety key out, hold the stop and speed up arrow at the same time while inserting the key. Release the buttons. You will then be in diagnostics.
You then press the stop button one time.
If you are trying to calibrate the incline you just need to hit the incline up button and the machine will do an incline calibration. The unit should go all the way to the top and return to the bottom when completed.
If you need to calibrate the speed you will need to press and hold the speed up button on the console until the display reads 85. The machine should then be running at its maximum speed (either 10 or 12 mph depending on the unit)
The display will show a speed on the console and should be within .3 of the maximum speed.
If it is not then it will need to be adjusted using a potentiometer on the control pwb.
To access the control pwb open the hood cover. Should be 3 screws in the rear of the cover and 2 screws on the bottom of the unit.
Once inside the cover locate the control pwb. On the control pwb there will be a yellow/orange potentiometer. This is the adjusting part.
Use a non-metallic phillips head screw driver to adjust the potentiometer either clockwise for faster or counterclockwise for slower.
Hope this helps!
Good Luck! Tim
Testimonial: "Although I haven't attempted this solution, but it makes perfect sense and will attempt it as soon as I get back to the treadmill - Thank you"

If the calibration does not pass you may need to check the speed sensoralignment. You must understand the instruction for calibration is under the hood for motor.
1) Remove the motor cover hood by loosening the 4 screws that hold it inplace (you do not need toremove them completely).2) The speed sensor is located on the left side of the frame, right nextto the front roller pulley (thepulley will have a belt around it that also goes to the motor). Thespeed sensor is small and blackwith a wire connected to it.3) Make sure the sensor is as close as possible to the pulley withouttouching it. You will see a magneton the face of the pulley; make sure the sensor is aligned with themagnet. There is a screw thatholds the sensor in place that needs to be loosened to adjust thesensor. Re-tighten the screw whenfinished.
2) if the problem persist you must Test the main motor for open, ground 3) the main control board faulty. See the block diagram that I did as person like you that understand that 90% of functions the main motor controller board has effect.
good luck. sincerely. God bless you.

With the safety key in place, turn the treadmill ON . Press and hold SELECT. Now you can perform auto-calibration by pressing START.
(The treadmill will run through minimum and maximum speed and elevation. This will take 3 to 5 minutes. Let the treadmill perform this complete function. "END" will appear when auto-calibration is complete. When auto-calibration is complete, it will take about 30 seconds for the treadmill to reboot and return to the start-up screen)
If it doesn't help then the motor control module is faulty. You have to replace or repair the motor control module.
