Why is there no belt movement?

If the belt on your Nordic Track T12 si treadmill is not running even though the display and other functions appear to be working, there are a few troubleshooting steps you can try:

1. Check the safety key: Ensure that the safety key is properly inserted into the console. The treadmill will not operate if the safety key is not securely in place.
2. Reset the treadmill: Turn off the treadmill and unplug it from the power source. Wait for a few minutes, then plug it back in and turn it on. This can help reset the treadmill's internal systems and may resolve any temporary issues.
3. Calibrate the incline: If you recently used the incline function, it's possible that the calibration of the incline mechanism is off. Consult the user manual for instructions on how to calibrate the incline. This process may vary depending on the specific model of your treadmill.
4. Check the motor and drive belt: Inspect the motor and drive belt for any signs of damage or wear. If the drive belt is loose or worn out, it may prevent the belt from moving properly. If necessary, consult the user manual or contact Nordic Track customer support for guidance on inspecting and adjusting the motor and drive belt.
5. Lubricate the belt: Insufficient lubrication can cause the belt to stick or not move smoothly. Refer to the user manual for instructions on how to properly lubricate the treadmill belt. Use a silicone-based lubricant recommended by the manufacturer.
6. Contact customer support: If none of the above steps resolve the issue, it is advisable to reach out to Nordic Track's customer support. Provide them with detailed information about the problem and any troubleshooting steps you have already taken. They will be able to offer further assistance, including potential repair options or guidance from a technician.

The Steps for Newer Style Console Calibration:

1. Locate the calibration area on the rear or underside of the console (a hole, near the console's center, that goes through to the electronics board. (This hole should not have a screw in it.)
2. Insert a pencil (eraser end), into the hole and feel around for the cal button (will click when pressed).
3. Press the button 2 times (with the pencil eraser). The first click should show CL11 in the console, the second click should show CL21.
4. If the process was done correctly, and CL21 appears in the console, you are in "calibration mode." The next few steps consists of pressing buttons on the console and observing settings. This will not require any other tools.
5. Press ENTER. CL22 should display in the TIME window and (??) in the SPEED window.
6. Press ENTER. CL23 should display in the TIME window and (??) in the SPEED window.
7. Press ENTER. CL24 should display in the TIME window and (??) in the SPEED window.
8. Press ENTER. CL25 should display in the TIME window and (??) in the SPEED window.
9. Press ENTER. CL26 should display in the TIME window. You should then see the letter "E."
10. Press ENTER. You should see "SS" or "55" in the console.
11. Push the STOP/START button. For safety, at this point, you should step off, or be off, the treadmill.
12. Push the ENTER button. The walking belt should start to move, accelerate to maximum speed, then stop on its own.
13. When the belt stops, the incline should self test by raising to its highest incline position, then lowering back down to its lowest position.
14. Once the incline test is complete, push the POWER button 2 times. The unit should shut off and the console should go completely blank. If this happens, the treadmill is done calibrating and is ready for use.

If the letter "F" appears in the SPEED or INCLINE window when the power button is pressed 2 times, the treadmill is indicating a failure somewhere either in the SPEED or INCLINE (depending on the window the "F" appeared in). Troubleshooting the failure would be the next step.

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..

The incline operation and the walking belt operation are independent of each other. The walking belt should run regardless of the incline operation.
Although I have never had a problem with the gears in the incline motor being defective, you may need the motor replaced.. Try an incline calibration.
With the safety key in place, press start to start the machine. Press incline up. While the numbers are changing, remove the safety key. Release the incline up button. Reinstall the key, the machine should calibrate . After calibration, retry the operation normally.
Because the circumstances here are unusual, I would next disassemble the right upright and inspect the wiring harness for damage. During assembly, it is easy to pinch the harness (usually at the bottom of the upright), damaging the wiring to the console. The console may work, the the information may not get to the motor control PCB. The machine may have worked for a period of time before the damage became apparent, the flexing and movement of the frame eventually will eat through the wiring causing a number of unusual symptoms.

The vibration of the move may have loosen the connectors. Unplug unit remove motor shroud you will see the motor control board pull and reconnect all connections also check the connector in upper electronics then on unit see your display works and see if you have motor and belt movement.
