• 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..
  ..Hope this helps..-JR

  the machine will come on and let u select a program, but it starts to blink P0 and won't start going (after pushing start of course). We never had this problem before - what do i do?

• L5 error
  
  
  check under the motor housing. there is a sensor next to the belt pulley that needs to be parallel and about .25" from the magnet on the pulley. This error code pops up when the teadmill doesn't get speed info back from this sensor.
  
  it doesn't have anything to do with the motor brushes.
