Treadmill incline stuck @ steepest level (highest)

I cannot find my user's manual for the treadmill. I've tried unplugging it; turning it off/on; etc. I've pretty well pushed every button a few times and nothing happens.

I went through one of the pre-set programs (start to finish) with the hope that the incline would at least drop when the program was finished -- it didn't!

I remember that this happened once before, years ago, but am stuck with a poor memory and no manual - help!

    The incline adjustment on my Horizon T91 does not function. The display shows each incline percentage, but the treadmill does not raise. We had replaced the console and there was no improvement. Our next step is to contact Horizon. Is there any other way we can fix this if it happens again when the treadmill is out of warranty.

    Ramp stays in fully up position after program 1 has counted down the 30 minutes and finished. Ramp will not go down on any program number. When switching on the treadmill it seems to attempt to raise the treadmill even though it is in highest position. Will a system reset fix this problem and how do I carry out this reset. Any help appreciated

1)Connect the wall power to the treadmill
2)Remove the safety key
3)Hold down the red stop button and red increase speed button (this is the red triangle next to the start button)
4)Insert the safety key while holding both buttons down in step3
5)The treadmill will now go into a diagnotstic calibration mode
6)Let go of both buttons in step 3 and press the oval stop button once
7) Now press the up arrow green incline button once(This is located to the left of the yellow program button)
8) Allow the treadmill to go through a calibration cycle, once it completes and stops moving remove the safety key count to 3 and reinsert.

I had the same issue with my Proform XP590 and resolution was to run through the re-calibration as described by the technical document found under the hood. The Pro-Form customer FAQ helped me out.

I have an Epic T60, six years old-- bought it at costco. Was messing around one day and ran it up to 12 % and it stuck. Researched about calibrating the inline, the incline motor and the incline sensor. I got home and tried to recalibrate the thing and it didn't work. I removed the motor cover and took it apart (on its side). I found that the instructions available on the web for changing the incline sensor were accurate but what happened with mine was the screw that held a washer on the end of the threaded auger shaft had snapped with the pounding of running when the treadmill was at 0%. I took the incline motor off, tools were 14 mm wrenches only. I had to take the threaded rod out of the motor gear system and take it to my shop and drill out the old screw. Then I used a tap and created new threads in the end of the rod. I used a 5/16 bolt to replace the broken screw and put the thing back together again. It seems to word perfectly. I had to recalibrate it though. even though the new bolt is bigger, It calibrated fine.

Have a Nordic Track Model #A2050. Same problem as jimmohn posting above. Incline stuck in up position. Fix by removing the jack-screw (pin & clevis) on both ends, manually unwinding screw out of shaft and replace with new screw & washer. The screw size is M6 x 3/4" long (metric). Instantly solve the stucked incline problem.

This worked for us: turn the beast on its side. You will see the motor with its screw bolt all the way extended from the gearbox.
Now, have one person follow the instructions for calibration (hold stop and speed+ while inserting safety key, and then pressing stop once, then incline button up). We took a hammer and gently tapped the gearbox as we heard the motor engage and it the screw bolt started turning and took incline down to zero.

I have a Nordic Track T7Si and turning it on this morning resulted in the elevation to the highest level of the incline. The display kept stating "calibration" and flickering between 0 and 1. Steps to remedy it.
1. Unplug
2. Trip the reset switch (not sure if necessary, but I did it)
3. Step to the side of the treadmill and plug it in.
4. Push START and SPEED UP buttons together
5. Insert safety key
6. Push STOP after a few seconds
7. Incline will return to zero

    hi I have tried all of these. my nordictrack is still stuck at max incline 10% . shows message "wait calibrating incline" . after 30 sec shows normal display but incline still stuck at 10%

    Had this problem for a while. Stuck at 12% and calibration not working, although I could hear the motor trying. I opened the motor hood and tried moving the incline screw manually with no luck. Then, with hood open and treadmill on its side, I tried the calibration again. I saw the incline motor jump a little and just kept trying. As it struggled back and forth something finally loosened up and it stayed working! Back to normal now.

How to recalibrate 8600 incline trainer

To initiate the calibration routine, hold down the SPEED +
button and the SPEED - button simultaneously for three seconds. During the calibration routine, the INCLINE
TRAINER will automatically rise to the highest incline level and then return to the lowest incline level.

P.S. This is listed in your user manual in the "Troubleshooting" section if you don't have a user manual then you can get a pdf copy of it here

Hello, WE have the model 4100i treadmill and the elevation is stuck in the highest position and won't reset to zero. How do I fix this or who can I call for this repair? Thanks, Tom

Try the calibration procedure found in the troubleshooting section of your manual first. Here are the basic instructions.
With the key in the console, press one of the Incline buttons. While the incline is changing (or the numbers on the console) , 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.
If it still doesn't move, remove the cover. Find the incline motor. You will see a slot in the end of the motor. Using a drill with a standard slotted screwdriver bit, spin the motor counterclockwise (if it is having difficulties spinning, turn clockwise instead) for just a couple seconds. Now do the calibration procedure again.
I have had machines that got stuck before. Once released and recalibrated, the operation was OK.
The service number for your machine is found on the model number sticker on the frame of the treadmill.

Epic Comfort step 425mx treadmill that we have is stuck on incline. How do I get it to go back down?

This happened to my treadmill. You need to get to the motor and see if the belt is fraying. If so, the fibers may have gotten entangled in the motor causing it to stay at the highest incline level. Once you clear this the treadmill will go up and down again. Hope this helps!

Treadmill stuck on highest incline....and motor running...but seems stuck...won't come down

If the incline is stuck, it could be a problem as simple as the gearbox on the motor being jammed. Unplug the treadmill remove the motor shroud then remove the incline motor from the treadmill, reconnect the wiring, plug in the treadmill and then try to run the incline motor outside the treadmill. Many times, this will unjam it if that is the problem and then reinstalling it in the treadmill will get it to work. If you have the same problem or it doesn’t run outside the machine and you can hear it try to work, you need to replace the incline motor.
If the incline motor does not move, we need to figure out if the motor is getting voltage. Use a simple multi-meter and set it to AC volts. When you put it into calibration, it tries to calibrate the directions one at a time. Measure across the white and black wires first, then measure across the white and red wires second. If the motor is getting voltage you will read 120VAC (or thereabouts) one one of the measurements. If you have voltage but the motor won't move, you need to replace the motor. . If the incline motor does not move and you have done the voltage test and you do not have any voltage present, there is a problem in the electronics board that supplies the power, you need to replace the board.

My nordic track treadmill won't decline

My wife had the same problem with her treadmill. I turned the beast on it's side, and unscrewed the plastic casing that houses the motor, computer, and all the electronics to the treadmill. I unplugged the incline/decline motor. Then on the bottom of the treadmill the long threaded rod that causes the incline needed to be moved. So I unbolted it from the catch, and manually screwed the rod back in with a wrench. Now the treadmill works fantastically, of course the incline/decline mechanism has been disabled, but I would rather have a treadmill with the incline disabled than have one always on 100% incline. Hope you found this helpful :)

My treadmill is stuck at the highest incline and will not decline

Although it is fairly rare the incline motor can jam up into the highest position and get stuck there. To fix this take off the plastic hood that covers the incline motor and depending on the motor you should be able to wind it with your hand out of the highest position. When it is out of the highest position run the calibration as described in the owner's manual and it should go all the way up and all the way down. If it is not this type of motor that can be wound by hand then the first and last thing to do is to try calibration of the incline as described in your manual. If this does not work then a new incline motor is needed.

Under the hood there should be a tech sheet with calibration instructions. I have not worked on these for several years or I would rattle off the procedure. If the sheet is still there make sure you put it back in the plastic sleeve for next time..... Eric
