Q:

proform treadmill 831297340 suddenly stops.

A:

Thank you for your question.

I am sorry you are having a problem with the treadmill. The most common cause for this is a dry walking belt. When the belt is dry, it causes the motor to work harder. 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 to 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 [ Sears parts direct | Sears Parts Direct . 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, 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 the belt seems to be fine, the problem could be a motor control or a motor. Both of these parts can be expensive to replace. To be sure, I recommend having a service technician come out and diagnose the problem. you can have it repaired at your home by a Sears technician.

Please let me know if you need further assistance on the treadmill.

Thank you for using Manage my life.

Q:

how do i install proform walking belt replacement model 831297340

A:

Thank you for your question.

Replacing the belt on your treadmill is fairly difficult and time consuming. In addition, there are no really detailed instructions for replacing it since a professional would typically do that type of service. We do not have a treadmill service manual that shows how to replace the walking belt either.

The basic instructions are listed below to help you.

  • Unplug the treadmill from the power source.


  • Remove the motor hood on the front of the treadmill.


  • Remove the right foot rail. The foot rail is stapled to the walking board. To remove the foot rail slip a straight blade screwdriver under the foot rail near the staple. Then twist the screwdriver to remove it. Most of the time the staple will pull through the foot rail, this is ok. Then use diagonal cutters to remove the staples. To reinstall the foot rail use the screw provided with the walking belt. Use the holes made by the staples for the screws.


  • Remove the rear roller adjusting bolts. Be sure to count the number of turns it takes to remove the bolt.


  • Remove the front roller adjusting bolt. Make sure to count the number of turns it takes to remove the bolt. Then when you reinstall the bolt, you can get it in the same place. If your model does not have a front roller adjusting bolt you will need to remove the bolt that secures the right roller bushing. It helps to incline the treadmill when removing this bolt. Once it is inclined, flex the frame to the left and the bolt should come out enough to release the roller bushing.


  • Remove the front roller.


  • Remove the screws from the right side of the walking board. Then lift the walking board and slide the walking belt off the board.


  • Reverse the instructions to reassemble the treadmill.


  • Before installing the motor hood carefully check the operation. The drive belt might need to be adjusted.


I have added the instructions for adjusting the walking belt below.

Again, this is a fairly involved repair, so if you have any concerns or reservations you may want to consult a professional.

I hope this is helpful. Please reply below if you need further assistance.

Q:

I have a ProForm treadmill. When I plug it in, it starts at fast speed, won't stop or slow down. The only way to stop it is to pull the plug. What is wrong?

A:

You either have a motor shorted to ground or a defective motor controller board. You need a technician to diagnose the problem and find out which is the problem.
