Mr Wiz must have read this too, but--
From Randy's blurb on the 68100,
" Electronic current limiting automatically shuts down power during overload or short-circuit conditions."
So what do you do to restart it after that? The product manual just says to contact WFCO tech support.
The thermistor disc may not show damage on one side, but on the other side and it can be hard to see.
This is the second 68100 Mr Wiz got on a warranty exchange after the first one. Can't remember what the issue was with the first one or how long ago that was for any warranty on this one.
