Q:

Proform treadmill Proform - 520X - 831.293050

A:

Thanks for the inquiry and for being a valued member.

I am sorry to hear of the issue you’re having with the treadmill. I know how frustrating that is to have happen.

By what you have stated I suspect the treadmill motor is working too hard and overheating. When the motor over heats it can, cause the overload in the motor to open or it could trip the breaker. 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.

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.

If you would feel more confident have a Sears Home Service technician help assist with the diagnosis/repair, you can call 1-800-469-4663, or click here to be directed to the page to set up service.

I hope this helps and thanks for using SearsPartsDirect.com. We appreciate your business.

It sounds like you need to adjust the tension on the walking belt for your treadmill. I will cut/paste the directions for that procedure.

Adjusting the Walking Belt Determine if the belt is running parallel to the foot rails, if it is not adjust the front roller to make the belt run true. NOTE: On some models there are no front roller adjustments. If so go to step B.

  • To center the walking belt follow the steps below:
  1. On the right side of the front roller there is a bolt or screw that goes thru the roller bracket or bushing then thru the shaft of the front roller and out, most of the time back into the bracket.
  2. To move the belt to the left side of the treadmill turn the screw/bolt in the front roller clockwise until the belt runs parallel to the side rails.
  3. To move the belt to the right turn the bolt/screw counter clockwise until the belt runs parallel to the side rails.
  • To adjust a loose walking belt that is running straight.
  1. Turn both adjustment screws at the back of the treadmill an equal amount clockwise in 1/4 inch increments.

  • To adjust a loose walking belt that is off to one side.
  1. If the belt is to the left side tighten the left adjustment screw more than the right screw to get the belt centered.

If the belt is to the right side tighten the right adjustment screw more than the left screw to get the belt centered.

Thank you for using Manage My Life!

If I have a loose walking belt that is running straight and my husband already turned the adjustment screws at the back of the treadmill as far as they go and the belt is still slipping, what other suggestion do you have as a possible issue? Could it be the running belt itself, or perhaps a roller that needs replaced?

Q:

Treadmill operation 831293050 Proform Proform 520x

A:

I know that it can be very frustrating to have issues with your treadmill. There are several things that can cause the unit to have this type of problem. You should lift the sides of the walking belt and feel the bottom of the walking belt and the top of the walking board. Feel for places that are rough. the belt and the board should feel smooth and slick. 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 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 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 this is working, then I would suggest you try recalibrating the unit. The images below will provide these instructions for you. If you don't feel comfortable doing this yourself, please click on the link to schedule service: Sears Home Services. Click on "Get Started" and follow the directions, click on the red "NEXT" button to continue. I hope this helps. Please feel free to let me know if you need further assistance.
