Every time I put the key in my Proform 590T, the incline rises for a second, and lowers for a second while displaying 2 hash marks. Then, the home screen comes. All speeds work fine for walking/running, but the incline does not work at all. Going through the service mode to recalibrate the incline does not help. Any ideas how to make my incline work again?

is it missing ?
if so you can buy a new one.

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.
    

Run the software calibration for troubleshooting. Test the s. sensor for open or faulty .clean it and tight very well.

ICON CALIBRATION INSTRUCTIONS- INCLINE
1) Press the Stop and the Speed Up keys down while inserting the safety key. If this doesn’t work, click on the help topic entitled “Alternate Calibration Codes” for key sequence instructions to enter calibration.
2) Press the Stop key one time. The Time window should read EP:2P. Some newer models may also say FP, Pass, or the like. This means that it passes the EPROM test.
3) Press either incline key and the incline will calibrate automatically.
4) THIS IS A VERY IMPORTANT STEP BECAUSE YOU WILL GET AN ERROR MESSAGE IF THIS STEP IS SKIPPED.After completing calibration of incline, press the Stop key and then remove the safety key.

If the incline moves but you it will not operate normally nor calibrate, check the wiring from the incline sensor to the power board. If all looks normal, put it back in calibration and see if you see a blinking “- -” symbol in the incline window when you are calibrating. If not, the incline sensor is bad.

If the incline moves but only just a bit, it could be a problem as simple as the gearbox on the motor being jammed. We remove the motor from the treadmill, reconnect the wiring, 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. If the console is powering the drive motor as normal, you can bet it is getting an incline signal and the power board needs to be replaced (some models have an integrated power board/controller) so if there is only a single board the whole board has to be replaced. It is possible the console is not giving the proper signal but we've never seen it happen in thousands of treadmills.

Press the Stop and the Speed Up keys down while inserting the safety key.
Press the Stop key one time. The Time window should read EP:2P. Some newer models may also say FP, Pass, or the like. This means that it passes the EPROM test.

Hey Jeff,
You will have to loosen the 2 bolts that hold the drive motor on to the frame, then stretch the drive belt and rotate the flywheel until is fully engaged on the pulley then tighten the bolts. Hope this helps

ProForm Treadmills have a reset procedure for the incline function. With the key inserted in the console, activate the incline; while the incline is changing, remove the key. Wait 30 seconds, then replace the key. The incline should to maximum, then to minimum, resetting its limits. It worked for mine just 10 minutes ago; the procedure is in the manual if you have it. Good luck!

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
