Treadmill Incline Motor Repair – Nordic Track 1750

How to deal with the error message “The incline calibration is not correct; Trans Max value = 0” and how to perform a treadmill incline motor repair.

Trans Max value = 0

With much searching on the internet, I couldn’t find much about treadmill incline motor repair and this error, so I’ve decided to publish my findings for any people encountering the same problem.  In searching about incline motor problems I did find some information. The most common problem is the gears getting jammed, and this can be solved by manually cycling the incline motor top to bottom. This can be done by turning the screw on top of the fan.

This will take you about 4 hours if you try to do it with a screw driver, you may be able to clear a jam, but you won’t cycle through 0 – 15 incline.  So I recommend using a cordless drill
with a screw driver attachment.  You do not have to take the motor out to do this, I just used a picture from when it was out, as it was easier to see.  If the motor doesn’t go through the range of motion there may be some broken gears indicating you need to replace the motor.  If you are getting the Trans Max Value = 0 error, it is unlikely to be just a gear jam.

I went ahead and ordered a replacement motor. Removal of the previous motor was fairly straight forward. Make sure the treadmill is powered off and unplugged and has been for a significant period of time so you don’t get shocked. Take the cover off the treadmill.

You will need to disconnect the wires indicated by the yellow arrows. Don’t forget to disconnect the incline motor sensor indicated by the yellow arrows in the next picture. Just the red piece, the black connector piece should stay on the board.

After disconnecting these wires you can disconnect the two bolts holding the incline motor in place. These can be difficult to access in the cramped space of the treadmill.

I recommend removing the bottom bolt first(left). Once these are removed the treadmill will swing down to a lower portion, so be ready to swing the motor up so it doesn’t colide with the motor control board.  It sounds difficult but it’s not.

Installation is opposite of removal. Once the new one is installed, Click on the information button and then on the setting gears to get into the incline calibration settings.  This should run the incline all the way up and down.

There is a third cause of the Trans Max Value = 0 error. Interruption of the connection between the incline motor and the upper console.  The incline motor sensor connection on the control board can be loose, or wires can be cut or fractured on installation.

In my case the wires got caught in the foot connection, and cut two wires.
