L5 or LS is short for Low Speed error. It basically means that the speed sensor is not picking up a signal. Unfortunately its a pretty vague error code and can be caused by several different problems. First you have to determine whether or not you have belt movement. If you have a LS with belt movement you know that it is related to the speed sensor itself (or the MCB motor control board - the part of the MCB that handles speed sensing function). If you are getting an LS without belt movement you have to check to see if you have power output from the MCB. If you have no power output, check fuses, if fuses are good, you will need the MCB replaced. If you have sufficient output its drive motor related. Aside from a problem with the drive motor, it is possible that another factor is stopping the motor from turning (ie locked up roller bearing, foreign debris, etc.) If it is a case of faulty electronics the next question is, is to figure out what caused it to fail. Most MCBs don't fail on their own, something else usually causes them to fail. The bottom line: The LS error can be complicated and should really be inspected by a professional to full assess the issue. What I am saying is call the manufacturer and if it is under warranty send the treadmill back.
