I understand the concern this noise would cause.  The problem may be the walking belt or the motor.  I highly recommend having a qualified technician diagnose and make these repairs.  This is not a usual problem.  You can schedule a Sears technician here; Sears Home Services  .  If you would like to make a couple of checks first, disconnect power to the treadmill.

Remove the front hood over the motor area and remove the drive belt from the motor pulley.

Walk on the belt and try to create the noise. If you can create the noise this way hopefully you can determine what is causing the noise.

If you can't create the noise without the motor, connect the power and start the motor with the drive belt off. Don't touch anything inside the motor cover once plugged in. If the noise is coming from the motor, you should be able to tell.

If you don't get the noise this way, disconnect power again, inspect the drive belt for cracks, stretch marks, etc. The drive belt might be the source of the noise.  Parts for this model can be located at Sears Parts Direct .

Thank you for your question.

I am sorry you are having a problem with the treadmill. If the console is lighting up we know the treadmill is getting power. You have already checked the motor and it is fine. Based on that, I recommend checking the light on the motor control. To access the control you need to remove the hood. Then plug the treadmill in and turn the speed up. The light on the motor control should blink if it is receiving the signal from the console. If it is blinking, I suspect the motor control is the problem. If it does not blink, the problem could be a broken wire or defective console. I recommend ohmming the wire harness from the console to the motor control. If the harness is fine, I suspect the console is the problem. Once you determine the problem, the parts can be ordered from the following link.

Thank you for the link. I have tested wires going into and out of the motor. I have power going into, but not out of the motor itself (red and black wires going from motor to circuit board).

This could be a situation with the motor and/or motor controller board. To test the motor you will need a volt meter. Unplug the treadmill from the wall and then remove the motor hood. Disconnect the red and black leads from the motor at the controller board. Connect the meter leads to the motor leads (red to red/black to black) and set the meter to read DC volts. Then plug the treadmill into the wall and put the safety key onto the treadmill but DO NOT press any other buttons. Have the meter arranged where you can see it as you stand on the treadmill.

Once you have the meter where you can see it, start walking on the treadmill. Do not press any buttons, just start walking on it. The readout on the treadmill console should read the speed you are making the treadmill go. When it gets to 3MPH look at the meter and see what the DC voltage is. The treadmill motor will act as a generator and will "make" electricity when you walk because the belt is forcing the motor to turn. At 3MPH the motor should generate 28VDC, anything less than that and the motor is bad.

If the motor tests good then we can be pretty certain the controller board has failed. If the motor test shows less than 28VDC then the motor is bad and will need to be replaced.

You can go HERE with the model number to order whichever parts shows to have failed.
