This happens whether I am walking or running. The machine is ten years old. It has not been abused or subjected to anything more than moderate speeds at no incline. Shortly after I purchased the machine, it stopped working. After my complaint was ignored by Life Fitness for weeks I threatened to sue the retailer I purchased the machine from. That finally prompted Life Fitness to send a service person who ended up replacing the board. Unfortunately, the script on the board was unreadable, displaying only scrolling gibberish. I suspect it was used. Although I complained and asked for a replacement replacement it was never sent by Life Fitness. Without being able to interface with the board I was only able to use the machine in the most basic manner using the few controls that actually worked. I mention this because I will not be able take advantage of any suggestions that require using a diagnostic readout on the programmable screen.
Hi There, strange activity of the upper board could be a result of a bad power situation from the lower board, or we have also seen the main upper board flake out due to bad connections and failed timing parts. You can contact buyfitnessrepairpartsDOTcom for more help if needed. Good Luck.
Hello there. Is the model of the device 91T? If so, there are plastic covers on the engine. And there are motor coals there. You have to change them. It has been tested many times and has been fixed.
Based on the symptoms I would say the control board is defective.
