RE: Dead Grizzly speed control/VFD

Mine died suddenly. One time it worked fine, next it wouldnt come on. I
opened the switch box and the fuse holder was broken off- must have
simply been the spring pressure of the fuse holder that just blew the
end off the plastic fuse holder. A simple replacement with a better
quality holder.

Doesnt sound like your problem, but you could have had a similar
connection going loose. At least open the box and look for obvious
mechanical failures.
