Do these things have internal fuses?
Seems they do.

Thanks!

Pulled the housing off.

Managed not to electrocute myself via the high-voltage capacitor in
there.

Pulled the only fuse shown on the schematic that was taped inside the
housing. Tested it and found it a-ok.

Replaced the fuse.

Re-attached the housing and.......

..... it worked!!! ????


My only guess is that there was some sort of thermal circuit breaker
(that I am too clueless to ID on the schematic) and it returned to
normal temp during disassembly/reassembly. Doesn't really hold water
though, bc after initial failure it sat for a good hour and the period
of use before it stopped working was sooooo short.

Go figure....
