Thanks to all who replied ----
Turned out that replacing "intermittent transistor" Q4 on the control board
repaired the problem.
Replaced with a 2SA933 out of another unit, (works great). No other problems.

Can anyone of you Microwave Oven Techs. help us with this unit, fan & light
will start running by itself, but not the h.v.?
I did seem to trace it to "I think" a small transistor Q4 on the control
board (can't find any cross reference for it or a sub).
It's marked N411-92 on the transistor, location Q4 on the control board.
Measures bad with a standard transistor tester, but don't know the type, or
values?
Can anyone help with this one? Thanks. David.
