Question and Answers

Q:

The speed varies greatly on my treadmill model 831293050 all by it self. What part do I need?

A:

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 [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.

Q:

treadmill mod # 831293050 house flooded ( treadmill under water) motor stops after stepping on belt... sounds like a bearing noise how to troubleshoot

A:

Thank you for your question.

I am sorry you are having a problem with the treadmill. If the belt is slipping, you will need to determine where it is slipping. First, unplug the treadmill and remove the hood. Then plug the treadmill in and start the motor. Once the treadmill is running carefully step on the belt. As soon as you step on the belt, watch the front roller by the drive belt. When it slips find where it slips. If the roller stops, the drive belt needs to be tightened. If the front roller still turns when the walking belt stops, the walking belt needs to be tightened. The instructions for adjusting the belt are posted below. Click on the image to enlarge the image. Now to the bearing noise. You will have to pin point where the noise is coming from. The noise could be failed bearings in the motor or the rollers. I just want to warn you if the treadmill was under water, you could have multiple failures. The failures may not all show up at the same time. I have seen customers fix one problem then another problem comes up.

Q:

Proform 520x treadmill has power to machine but doesn't transfer to console

A:

A number of different failures could be causing this problem. You could have a tripped circuit breaker on the treadmill beside the power cord. The power cord could be bad. You could have a failed power board or a bad wire harness connection between the power board and the console. You could have a bad console assembly.

You indicated that you have power to the treadmill. I assume that this means that you checked the outlet by plugging a lamp or small appliance into it. If not, I recommend that you check the outlet in that manner.

If the outlet is good, make sure that the circuit breaker on the treadmill beside the power cord is not tripped. Page 23 of your owner's manual shows this circuit breaker. Here is a link for you manual in case you need it: User's Manual .

I provided a wiring diagram and the technical information on the power control board in the images below. I recommend that you unplug the treadmill and check the wiring connections on the power board. You will need to remove the hood to access the power board. Check the wiring connections for the power cord and the console. You can use the information shown in the second image to carefully check the LED lights on the power board. You will need to plug the treadmill in to observe these lights. Do not make contact with live wires or contacts when you have the treadmill plugged in during this test. Unplug the treadmill as soon as you finish observing the LED light on the power board. If the power board is bad, it will need to be replaced. If it is okay, you could have a problem with the control console.

You can order parts from the Sears PartsDirect website.
