    Hi Doc!



    Main controller?
    Practice makes perfect
    If it ain't broke, don't fix it
    A picture is worth a thousand words
    If you want something done right, you have to do it yourself

    Check you supply voltage at wall outlet

    Hot > Ground = ?
    Hot> Neutral = ?
    Neutral> Ground = +/- 0.0 to 0.5 v max


    Fan lock signal. -- DC PCB issue !

    What version firmware does the machine have?

    It might be a good idea to check all of your fans. I've seen the wrong fan indicated by error code in the past. Good luck.
