The manner in which it shuts down can help determine what may be the cause of it. If you're using it for about 45mins solid and it shuts down, that's somewhat normal. After it sits for about 15-20 mins it should be ready to go again.

If just a few mins into a workout it shuts downs and loses power to everything there could be a problem with the circuit breaker causing it. It could also be the control/power board causing it. Which could be due to several other factors.

If the belt stops turning but the console stays lit, that will usually be caused by a bad controller.

If you can give me a bit more detail as to how it is failing we can try to figure out for sure what is going wrong.

Thank you for using Manage My Life!

I have a proform 415 that turns off as soon as you turn on the belt to run. The display shuts off and then comes back on.

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.

The basic instructions are listed below to help you.

  1. Unplug the treadmill from the power source.
  2. Remove the motor hood on the front of the treadmill.
  3. Remove the right foot rail.
  4. Remove the rear roller adjusting bolts.
  5. 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.
  6. Remove the front roller.
  7. Remove the screws from the right side of the walking board. Then lift the walking board and slide the walking belt off the board.
  8. Reverse the instructions to reassemble the treadmill.
  9. 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. Here is a link to order any parts you need. Sears Parts Direct .

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 .

Thank you for using Manage my life. Mark T.

A white powder on our J4I treadmill near the belt. What is it? How can we fix it?


The white powder is the belt lubrication coming off. This is normal and will appear sometimes. Eventually you will need to lubricate the belt. Most of the time lubrication is needed after 300-500 hours of use.

If you need to purchase the belt lubrication kit send us your complete model number off the frame of the treadmill and we will give it to you.
