You could disconnect the treadmill for few minutes,say 15 minutes and then turn it ON. If the problem persist, this is an indication of hardware failure. I have no idea whether you would be comfortable in testing electrical components and replacing it?

However, would give you some pointers . The NO display and NOT respond option is suggestive of one or combination of reasons :-

1. There is a loose connection. You need to inspect all wires running from control board to the console.

2. Hardware failure such as control board, transformer, fuse or even power tube.

If you have the instruments and would like to carry repair, revert and i would be able to provide you with few pointers.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

How to recalibate a pro-form 595LE treatmill.

follow this steps and fix it. 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.
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.

My pro form treadmill was stuck in the incline position. Now it is down but the belt won't run

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. 11_13_2011_7_47_47_pm.gif11_13_2011_7_48_35_pm.gif

Pro form 580 SI, power incline runs up as soon as it is plugged in and wont go down using console buttons.

possible it could be in incline senser but most likely the console needs replacing. you should always use a power surge protecter on a treadmill. power surges can blow out 1 resister on those circuit boards and there no good.

I have a pro-form 680 LT less than a year old. The belt seems loose, it catches as I run and I about fall over.

The walk belt should be tight (about 1.5" to 2 " when lifted at the edge), if not tighten screws at the rear. If the belt is tight enough then pull the front cover off and check the front roller. Sometimes the plastic drive pully slips on the front roller. If it only stops while you are running and is fine when you walk, i would go to the front roller.

I've got a Pro-Form 680 LT Treadmill. Right out of the box, it has the symptoms of being in Demo Mode. You place the key on the Console and it goes to zero but then every button you push causes three beeps...

Should be instruction in your manual on how to take it out of demo mode. I believe it is press the stop button and insert the key. Then press the arrow down speed button once and the letter D that was on the display will disappear. You may have other problem like a damaged upright cable.Call the number in your manual for service as you should have a free 1 year warranty.

My pro form treadmill - panel lights come on but belt not operating? Any ideas how to repair or who would call out - Derbyshire area? Thanks

If the light are on and when pushing the console start button the oval track lights (on the console) should move. If not, then your console is bad. On most Pro Form consoles you have to replace the entire console. Individual parts are not available.
