what does E0 mean on a silver king meat freezer

Not knowing what model Siver King you have, I can’t be certain,  But they do use Dixel XW260L controllers on many of there machines.  Problem is they use their own programming and don’t readily share it.  I believe you may have a evaporator thermistor that is open, But I do not find that in there manuals.
