Question and Answers


no power on the tredmill 831.298060


Thanks for the inquiry and for using

I am sorry to hear that the treadmill is powerless and inoperable, I know how frustrating that is to have occur.

I would start by checking all the wiring connections around the console area. It could be that a wire came loose and is interupting the power supply. I would also check the wire connections around the power cord to make sure all the wire terminals are nice and secure from the power cord to the electronic motor controller it connects to. 

If all the wire connections look good, there is a possibility either the console shorted or the electronic motor controller is shorted and a multimeter will be needed to test further.

If you do not have a multimeter, it would be best to have a technician assist with the diagnosis. If you would feel more confident have a Sears Home Service technician help assist with the diagnosis/repair, click here to be directed to the page to set up service. 

We wish you all the best with the diagnosis/repair on the treadmill, let us know if we can be of any further assistance. Thanks for using

Why doesn't the time, speed and distance light up on the console, I replaced the battery?


Without knowing the model number of the product I will not be able to provide any model specific information only general. If the console does not display any type of icon indicating it's powered up the likely failure is the console/display or a bad connection between the battery and the electronic board. If it does show signs of being powered up but just doesn't indicate speed and distance the reed switch is likely out of adjustment or it is positioned too far from the magnet on the flywheel. There should be a magnet located on the flywheel and as it passes by the reed switch it causes the display to show speed or distance.

Resubmit your question with the model number and additional details if needed for model specific information.

What part do I need for my treadmill that keeps decreasing speed?


Those parts are available for your model. On the 831.298060 the speed sensor is listed as a reed switch, part number 06.831. 138680, and the controller is 06.831. 137856.

You may want to run through the basic troubleshooting in your manual and the links below first as it is far more common for those symptoms to be caused by a problem with drag on the walk belt than a problem with the electronics. The basic maintenance on the belt is not only simpler and cheaper but if the belt is the problem then replacing electronics will typically not improve matters for long, if at all.

If the reed switch has failed the console will not display any speed and, typically, the controller will shut down the belt after it moves a short distance as a safety precaution (since it sees no speed indicated and suspects the belt may be jammed or blocked). A problem with the controller will usually cause the speed to fluctuate but if the speed continuously drops or stops due to a controller you likely have a bad motor as well and both may need to be replaced as a set. Considering the cost you may want to consult a professional for confirmation at that stage.
