Sorry to hear that you are having difficulties with your treadmill. I think that we could narrow this down to two items. There are indicator led's on the control board that indicates the board has power and that it is functioning. Ensure the power cord is unplugged from the wall and remove the treadmill lower hood. I have included a diagram of this unit at the end of this reply. After you have the hood off, take a close look at the wires where they enter the machine and any connections on the circuit board. After your have inspected them, go ahead and plug the machine in and see if any led's light up on the board. If you have a multimeter I have indicated the test points to see if the voltage is making it to the motor controller board if there are no led's lit up.

If there is voltage to the motor controller and it is not working, here is a link to Sears Parts Direct .

There are several different model possibilities and I have picked one, however be sure to enter your exact model number, ie: 831.297160, at the parts direct website and with any future replies if you could.

If there is only one led, and not the one illustrated as the +12V on the diagram below, I would also advise replacement of the motor controller.

I have also included below, the flowchart for diagnosing a no power condition.

If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website: Sears Home Services .

Let me know what you find and if I may be of any further assistance.

I know that it can be very confusing to have extra parts for your treadmill. These fasteners are guides to keep the walking belt on track and centered. However, there are no detailed procedures for this repair. Here is a basic description of the procedure:

  • Unplug the treadmill to disconnect electrical power.
  • Remove the right and left foot rails.
  • Remove the rear roller adjusting bolts.
  • Remove the screws from the walking board and remove the walking board.
  • Remove the bolts that hold the walking board to the upright frame.
  • Remove the adjusting bolts from the front roller.
  • Remove the front and rear rollers.
  • Remove the belt and replace it and the walk board if needed.
  • Reverse the instructions to reassemble the treadmill.
  • Lubricate the belt.

You can use the lubricant kit that is part number 134591. The Sears Parts Direct website has this lubricant kit available. If you are not completely confident in your technical ability to safely and properly replace this treadmill belt, I recommend that you have it replaced by a technician. Here is a link for the Sears Service website: Sears Home Services . If you need further assistance, please reply to this thread. Thank you for using Manage My Life.
