Question about Nordic Track NordicTrack Reflex 4500 Pro Treadmill

1 Answer

Why does my Nordic Track Reflex 4500 Pro incline automatically when I start it up?

When I insert the key the incline immediately starts going up and will not stop. None of the buttons work so I have to take the key out to stop it from rising. I have tried calibrating the incline but it is still doing the same thing.

You must tried again the s.calibration, for easy diagnose, and troubleshooting.
However you must Adjust the speed sensor, test it, clean it, and tight any plug or connector, see the diagrams attached and proceed according.
2) Lube the elevation motor, the shaft + gear, test the motor itself for open or short. see the diagram attached. If you machine use RELAIS test it for dirty, or open and repair.
God bless you

Treadmill incline not working

The incline system may need to be calibrated. To initiate the calibration routine follow the steps below.

Step 1
Place the key into the machine. The key's slot is located on the bottom of the console, below the start and stop buttons.

Step 2
Press any of the incline buttons and then remove the key from the machine while the incline is changing. Pause for a few seconds and then put the key back into the slot.

Step 3
Wait as the treadmill automatically shifts to the highest possible incline and then descends to the lowest level. The treadmill should now be recalibrated.

You should immediately replace the console. That console will just keep getting worse. This is endemic of this brand, however it usually happens a lot further in the life of the unit. When you call Nordictrack have your model number.

I have the EXP 2000 NordicTrack incline treadmill and it will not incline. Lost manual.

Manuals can be downloaded at
First perform an incline calibration.
Insert the safety key/magnet. Press the incline up button. While the numbers are changing, remove the key. Release the incline up button and reinsert the key/magnet. The machine should go to the top and then back to the bottom.
If it only starts then stops, the incline sensor may be defective. Be sure all the plugs are secure on the controller board.
If the sensor is defective, you will need to order a new incline motor..
If the incline motor does not move at all, the controller may be defective..

How do you reset the nordic track apex 6100 xi i paid a repair person $100 dollars to hit 3 buttons but now i can not remember. can you tell me what 3 button and in what Sequence

With the key in the console, press one of the incline buttons. While the incline is changing, remove the key. After a few seconds, re-insert the key. The treadmill will automatically rise to the maximum incline level and then return to the minimum level. This will recalibrate the incline system.
