LifeSpan Pro 3 Speed Surges
I have recently encountered a problem with my LifeSpan Pro 3 treadmill where after several minutes of use it will suddenly surge up in speed before calming back down to the selected speed. It is also likely to throw an E1 error while gaining speed after I have paused and then restarted a session after several minutes of use. A power off/on resets the error and it usually behaves if I start at a very low speed and ramp up slowly. This happens regardless of if the belt is loaded or not loaded. I have replaced the walking belt, lubed it up, checked the deck and the drive belt with both being in good shape. Any thoughts on what could be causing this? The surge up in speed is dangerous in that it can almost throw me off the treadmill!
