nordic track treadmill model # NTTL09510


Good afternoon.... I can fully appreciate your wanting to get your treadmill up and running again. I'm wondering if your treadmill might not be in demonstration mode. I did locate a link that will discuss this situation in greater detail. Though this link discusses a different model number, the mechanics are likely going to be very similar. Keep in mind that an expert will be responding within the next two business days if not sooner and will likely offer you more information and instruction. I hope this link will help guide you as to what might be wrong with your treadmill and have a nice day.

Our exercise equipment is critical to helping us keep up with our busy lives, so a malfunction is unwelcome.  I see Henry provided a very good link for help and I would use the recommended procedures to try to resolve.

First verify the unit is not in demo mode. When in Demo Mode, the console will go through a repeating lighting pattern. This mode will only become active when the treadmill is plugged in, the main on/off switch is turned on, and the safety key is not inserted into the console.

The Demo Mode was added to attract attention to the treadmill while it is on display. By default, all treadmills with Demo Mode will come with it turned on. Demo Mode can be turned off at any time.

Method #1 to switch from the Demo Mode:

  1. Press and hold the STOP button while inserting the safety key to enter the user information mode.
  2. Look in the Calories window. When Demo Mode is active, the letter 'd' will appear.
  3. Press the SPEED DOWN button to toggle the mode on and off.
  4. Once the mode is set as desired, remove the safety key.


  Second, unplug the treadmill and remove the motor hood.  You should find a sheet with calibration information. I would try recalibration before looking at other problems. If this does not reset the controller, then this may be is caused by a shorted wire or loose connection in the wire harness from the console to the power board. The problems could also be caused by a bad board in the console.  If you are comfortable making checks and repairs and have an ohm meter, you can test the resistance on the wiring and board. Remove the motor hood and the console and disconnect the wire harness at both ends. Using an ohm meter check the continuity of each wire from end to end. Check each wire for continuity with each other wire. If any wires have continuity to another wire in the harness or to the frame of the treadmill, replace or repair the wire harness. If the wire harness is ok, replace the console.  Parts and diagrams can be viewed at Sears Parts Direct .  If further assistance is needed, please reply.  Thank you for using Manage My Life.
