Lifespan TR1200i error code "E1". Help!
Whenever I select a speed and hit start, everything functions just fine.... for 6 second then..... Shut down. Display shows error code e1. I've replaced the speed sensor and it is properly aligned. All of my wire harnesses are plugged in tight. I hope that the motor controller board isn't toast. If you have any advice on how to track down the problem and fix it, I would love to hear it! Please do tell. Thank you.
