Tradmill incline issues

If your Nautilus T9.14 elliptical trainer is displaying the "service 72" message, it typically means that there is an issue with the incline motor. The incline motor is responsible for adjusting the incline of the elliptical, and when it is not working properly, the elliptical will display this error message.
Here are some steps that you can try to resolve the issue:

1. Check the incline motor connections: Make sure that the connections between the incline motor and the console are secure and tight.
2. Check for any debris: Make sure that there is no debris or foreign objects blocking the incline motor.
3. Check the incline motor fuse: Make sure that the incline motor fuse is not blown and replace it if necessary.
4. Check the incline motor itself: Make sure that the incline motor is not damaged or worn out, and that it is functioning properly.
5. Contact the manufacturer: If none of the above solutions work, it could be a problem with the incline motor itself and it may need to be replaced. Contact the manufacturer's technical support for further assistance and they may have more specific troubleshooting steps to help you fix the issue.

It's worth noting that this error code is related to the incline motor, so the incline feature may not work and you may need to use the elliptical trainer without that feature until the problem is resolved.

Sounds to me like the motor has a shorted field coil or open or shorted armature. The motor is bad, you can order a new one at the companies website.

ERR1 indicates a speed issue. In this case, the motor speed as reported from the optic sensor differs

from the speed setting.

Analysis: Optic sensor signal issue -- Either the optic sensor signal is not right, or it is read incorrectly, or

the signal is not reaching the display.

clean the speed sensor, test for open or faulty. tight the connector very well. RUN the software calibration for easy troubleshooting and fix it.

see the diagram attached. and follow steps.

God bless you

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.
    

15. 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.
    

Sensor is out of adjustment, follow wires and check to see if limiter sensor has been moved or is loose

Dear Sir:

Please the adjust the reed switch and clean, see the diagram.

Run the software calibration for easy diagnose and troubleshooting.

See my personal TIPS for diagnose and trouble.

sincerely. God bless you.

Renee, Here is how to recalibrate the incline motor. Read all of it It will be good to keep.
Plug in your treadmill, do not stand on the walking belt. Hold down the "Stop" and "Speed +" key and insert the safety key or magnet, let go of the two keys. Now press "Stop" key once. This puts you into the level 2 of calibration. Press the "Speed +" key slowly until you see 85 on the console, (at this point the display is going to show the percentage of motor usage and also the actual walking belt speed) at 85% motor usage your top speed should be between 10 and 10.5 MPH or (of 12 and 12.5) depending on the treadmill. You must know your treadmills top speed. (Important the motor may be damaged if you set the maximum speed higher than the maximum speed that your treadmill is made for). If the speed is higher than 10.5 or 12.5 then you need to turn the potentiometer down to the correct level. If the speed it to low you need to turn the potentiometer higher. Once the speed is correct you are done calibrating the speed. Press the (-) speed key to lower the percentage to (0). Next press the incline (+) button, this will make the incline motor go all the way to the maximum incline and come all the way down to the level position. Then remove the safety key and the treadmill will reset into the normal manual mode, when you re-insert the safety key. Matt

how long have you had this treadmill? usually when the hash marks appear it means that the console control board is not recognizing the incline motor. even though it does run a little bit that is just the basic test that the treadmill starts but resets after it does not sense the incline motor. These motors rarely go bad so it is more than likely your motor controller that is causing the issue. I have seen this case many times as i am a fitness repair technician. The motor controller fixes the issue 9 times out of 10

Technically, the Incline Trainer and the treadmill are two different type of machines. The incline trainer raises much higher so the card that is designed for the treadmill will not work on the incline trainer unfortunately.
