Treadmill stops working.

Treadmill Proform 830QT purchased in 2000 sometimes slows down or stops working abruptly, and
sometimes trips the onboard circuit breaker. Sometimes I can smell something getting hot and then it quits. I've already adjusted the belt and this hasn't helped. I don't want to invest alot of money in this due to it's age. Any suggestions and/or estimate of how much it is going to cost. I'm afraid it's something expensive like a motor.

I am understanding your concern over the issue that you are having with the treadmill as well as your concern over the pricing. Having a treadmill at home is certainly ideal, with the issues that you are having is something that is common. I placed a link that might help you figure out what can be causing the problem.

Thank you for your question.

I am sorry you are having a problem with the treadmill. By what you have stated I suspect the treadmill motor is working to hard and over heating. 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 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 |

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, 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. you can have it repaired at your home by a Sears technician. Here is a link for the website:
