• L5 - Actually is LS
  
  
  Stands for loss of signal - I had this problem several times.
  Several things can cause this. In my experience, I think it was a bad motor brush.
  
  The first time, the PWM Lower board, the one with the two big blue capacitors burned (the cables/posts) that go to the motor. I checked the motor brushes, they looked fine. I replaced the PWM board, but a year later got the LS error again, replaced the board one more time (btw, the brushes looked ok). A TM tech recommended I also replace the treadmill belt. Things ran well for about 5 months or so. Then it happened again, but this time one of the two motor brushes -the spring that helps keep it in place, didn't have any, well spring in the spring, replaced them, and now the thing works like the day I bought it.
  
  I'm of the opinion, that the root of the problem was the d#$@ brushes. Even though they looked ok, one of them at least was really not. And after all of this, I read somewhere that those should be replaced every 5-6 years in residential TMs..I think the same holds true for the walking belt..and lubricate that thing with the right silicon lubricant.. Hope this helps..

  thanks! it was working fine for the longest, but about three weeks ago i noticed the running mat seemed to have a little trouble starting. a little push on the mat made everything fine but tonight (11/26/08) it wouldn't even start up and the error message LS showed up in the screen. i opened the casing but had no idea what i was looking at. guess i'll need to take a closer look at the motor brushes. also, i never knew dreadmills needed a wax but it all makes sense. i've been online looking for user manuals for this dreadmill for the last 30mins!
