Hi, the belt is erratic this indicates problem with DC board or the motor. Manually push the belt in the direction in which it normally moves. If you have difficulty turning the belt, there may be an issue with the belt/deck friction. If the belt turns freely, there may be an issue with the DC board output.
Use a multimeter to test the black and red lead wires that connect the motor to the power supply. An external power cord connects the motor the power supply.
Most probably its a motor issue.Its got weak,because in most of the cases its seen.But in some cases the board is checked faulty.-------- Get the motor as well as board checked to confirm the fault.
This will help

SOURCE: Precor C 962 Display works, but when start key press nothing happens!

If the console takes batteries, replace them. If this does not work or your console does not require batteries, check the reed switch or optic sensor. Reed Switch: Unplug the treadmill and remove the motor hood cover. The reed switch is mounted on the frame next to the front roller pulley. There is a magnet glued into the front roller pulley. When adjusting the reed switch, make sure it is pointing directly at the magnet. Move the tip of the reed switch within 1/8" of the magnet. Also, check to see that the wire is not damaged, and is connected to the console.
Optic Sensor: Unplug the treadmill and remove the motor hood cover. The optic disk and sensor are located either at the end of the motor or the right hand side of the front roller. The optic disk spins between two sensors on the optic switch. The disk must spin freely without touching either sensor. The sensors can be moved by loosening the adjustment bolt holding the switch to its bracket. The switch can then be slid. Center the disk.

Remember :The controller for console or display have circuit for magnetic swithc.

Treadmill belt runs too fast and will not power off with control panel

Step 1:

test the speed sensor,m for open or faulty, clean it, and tight the connector. see the diagram attached.
However follow the steps for RUN the.s calibration for fix it.
God bless you

Step 2:

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.

Some of the Vision Fitness t9450 treadmill incline and speed quick keys stopped working along with the manual speed and incline buttons

It sounds like you have a membrane issue. There are a number of different T9450 models and they all have slightly different consoles. You'll need your serial number to help pinpoint the parts you need. Your best bet is to go through the manufacturer ( and have them help you get the correct membrane and overlay.

We have a 600 mx and the pad is not working, the only button working is the start, i cannot increase speed or incline it either.

It is very unusual to have no incline or walking belt operation..
Try entering diagnostic mode and do a calibration. The instructions are found under the motor cover on a tech sheet.
1: with the safety key removed, press stop and speed up simultaniously.
2: Attach the magnetic safety key.
3: press stop 1 time.
4: at this time, by pressing the incline up, the incline should calibrate, going up to maximum then back to minimum..
5: press the speed up key, you will see the numbers on the console increase. The machine should start moving the walking belt around 25-30 on the display. At 85 the belt should be running at maximum speed.
6: press speed down, the machine should stop.
7: remove the safety key. Now replace the safety key and try the machine again.If any of this procedure didn't work, I would suspect a defective console. Otherwise, the motor controller may need replacing.
Good Luck

Ifit treadmill will not incline but everything else works, how do I fix the incline

You may need to calibrate the incline. Do this with the following procedure.
Safety key out
press the stop and speed up buttons at the same time while inserting the safety key. (you are now in diagnostics)
press the stop button one time only.
now press the incline up button (incline motor should start moving up)
incline will go up to the top and then all the way to the bottom. when it gets done you can remove the key. Reinsert the key and you should be operating normally.
Good luck Tim
