I posted a calibration procedure in the image below. If you calibrate the treadmill and that does not help, then you can use the wiring diagram and the troubleshooting at the bottom of that image to diagnose that failure. Note: Use extreme caution when checking live voltage. Wear electrical safety gloves and safety goggles. Unplug the treadmill after live testing is completed .

You can order parts from this page if necessary: Proform 765 EKG Treadmill Model 831.291770 Parts . Unplug the treadmill before accessing internal components and replacing parts.

Q:

My treadmill varies in speed when its running. What should I do?

A:

The motor controller might be failing on the treadmill. The walking belt might also need lubrication.

I suggest you calibrate the console on the treadmill first. I am sending you some images that show how to calibrate the console with the power board.

To test the walking belt lubrication, do not turn the treadmill motor on. Set the elevation to the highest level. Stand near the front of the walking belt. Push yourself firmly toward the rear of the treadmill. If the belt is properly lubricated the belt will take you to the rear edge of the treadmill and dump you off on the floor. If you move and stop, the belt needs lubricating.

The part number for the belt lubrication kit is 219168. You can buy it at [www.searspartsdirect.com]. The cost is around $4.00. The application instructions should be in the package, but in case they are not here is how to apply the lubrication.

Turn the walking belt until the belt seam is along the top of the front roller. Raise the belt on one side in the center of the walking board front to back as high as you can. Apply ½ the tube of lubrication to the walking board in a zig zag fashion moving from front to back. Move the belt until the seam comes up on top of the rear roller and lift the belt again and put the rest of the lubrication on the walking board in the same manner. Turn the treadmill on and walk on the belt for 10-20 minutes. Walk all over the belt to distribute the lubrication evenly on the walking belt and board.

If neither of these stop the speed from changing, replace the motor controller.

Q:

Why does my Treadmill, Pro-Form 765 EKG Model # 831.291770 stop any where from 5 to 30 minutes?

Why does my Treadmill, Pro-Form 765 EKG Model # 831.291770 stop any where from 5 to 30 minutes?

Sometimes when a motor fails on a treadmill it damages the motor controller. You might need to replace the motor controller.

If you have to wait 15-30 minutes after the treadmill stops before you can restart it, the overload inside the drive motor is tripping. Low voltage to the treadmill will cause the overload to trip.

If you are using an extension cord on the treadmill, eliminate it and plug the treadmill directly into a wall outlet. If this eliminates the problem, get a new extension cord with 12-14 gauge wire in it. If the problem remains, check the voltage coming from the house wiring.

Another possibility is a walking belt that needs lubrication. To test the walking belt lubrication, do not turn the treadmill motor on. Set the elevation to the highest level. Stand near the front of the walking belt. Push yourself firmly toward the rear of the treadmill. If the belt is properly lubricated the belt will take you to the rear edge of the treadmill and dump you off on the floor. If you move and stop, the belt needs lubricating.

If you can start the treadmill back immediately after it turns off, replace the motor controller.
