A:

Thank you for your question.

I am sorry you are having a problem with the treadmill. I looked up the model number you have submitted. This model has a speed sensor wire that can come loose. If it comes loose, the control does not get the signal and will shut off. To check the sensor wire you will need to unplug the treadmill from the wall. Then remove the hood. Once it is removed look at the left side of the front roller. You should see a black wire next to the roller. The end of the wire has a sensor that reads the roller going around. Turn the roller so the magnet is aligned with the magnet on the roller. There should be about a 1/4 inch between the magnet and the sensor. Once that is set, follow the wire back to the board, and check the connection on the board. While you are looking at the board check all the rest of the connections and look for burnt marks on the board. If it looks ok, replace the cover and check the operation. If it does the same thing you will, need a volt meter and feel comfortable making live voltage checks. If you have a meter and would like to diagnose it yourself, please let me know. I will be happy to help.
