I have one of these guys and it has served me very well for probably

From the manual, the model number is a JVM 250 BVC or JVM 250 WVC
(probably a white or black model).

In any event, this morning old Betsy decided not to heat anything up.
All the bells and whistles are there, fan runs, etc, lights action,
keypad works, just no heat. So I suspect more than likely the
magnetron or xformer.

I was wondering if anyone knows if there is a secondary fuse I could
check on this model before I turf it? Obviously main one is good as
everything else powers on.

The second question is that I remember installing this thing and
having to adapt a hole in the wall to an outside vent etc to fit it. I
am hoping that maybe a new model of the same make would have roughly
the same vent location so I do not have to rebuild that part to put in
a new one.

Or maybe it is standard for all microwaves? Does anyone know?

This happened on my sons microwave same symptoms. It was the high voltage
diode that was bad. New diode cured problem. If you are not hep on working
on these things keep your hands out of it. Killer voltage still in high
voltage capacitor. WW

Any clues or input appreciated.

I don't know the model. It could be a fuse. put it on

Chuckle. I just saw a twin to my similar-age over-stove micro on the
swap board at work, for $90. Briefly pondered if I should buy it for a
spare.

But seriously- if you can't repair it yourself, and don't wanna spring
for new, there are usually low-mile micros on CL and such, from kitchen
remodels. If you haven't priced them since you installed yours, plan on
crying.
