where the refrgerator goes is between some cabinets and it would take a
major redo to fit in a larger one. Had to settle for a smaller one than we
wanted because of the space.
Over the years almost all building supplies change sizes. The 2x4 studs get
thinner, the 3/4 inch plywood gets thiner. Then when you need to replace
something it is usually a total tear out and replace the whole room.

We have a built-in oven/microwave combo. Not sure what happened, but
the microwave quit working. It may just be a fuse, but it's very
difficult to get to to even check, and we'd have to remove the oven that
sits below it in order to check what's wrong with that microwave.
The over works just fine. We ended up just buying a free standing
microwave that sits on the counter.
My built-in microwave stopped heating after 12 years use. I looked into
fixing it and found the magnatron to be a very expensive part, so I
bought a replacement microwave [Same size same brand same options] for
less than half the cost of a replacement magnatron, and installed the
oven myself. That was two years ago.
Sometimes fixing something is just to satisfy ones ego when a complete
replacement is cheeper.
In your case, a replacement oven wasn't an option. Glad you got it
fixed . :D
Before you attempt to fix, let alone open a microwave open, you would
be wise to learn about their theory of operation, how the components
work, and how to not kill yourself. If you attempt to "learn as you
go", make sure you have a good insurance policy to provide for your wife
after you have gone.

$200? Did you order from an appliance supply instead of from MCM
Electronics, Dalbani, Premium Parts, etc? It's possible you could
have bought another small microwave oven and taken parts from it
because many magnetrons are identical. The mechanical fit of
the magnetron must be exactly the same or strong microwaves can
leak where the magnetron seals against the chassis.
What overvoltage diode? The electonic circuit board may have some
tiny ones, but I'd expect a MOV across the AC lines. OTOH
magnetrons are powered by thousands of volts provided by a circuit
consisting of a high voltage capacitor and high voltage diode
configured as a voltage doubler. This diode will measure as an
open circuit with digital multimeters because they apply only
about 2-3 volts for ohms or diode measurement, and high voltage
diodes consist of several diodes connected in series and require
more voltage to be applied , so a higher voltage has to be applied
to it to conduct. Some analog meters will do that on their
higher resistance scales, like 10x or 100x, or you can use a
source of at least about 9 volts DC with a resistor of at least
10,000 ohms in series.
How many microwave ovens should I have bought before I found the one
that fits properly?
The parts were bought from PartsDirect.com. In case you didn't notice,
I got them from there because they had a return policy and I could get
it next day air.
Maybe I said it wrong and it is a high voltage diode. I think you got
the point though.
How do you *know* this is the same part? Because it LOOKS the
same? Because it has the same number stamped on it? How
do you know they aren't "rejects" (failed some critical
characterization) that People's Microwave Oven Factory #234
rationalized was unnecessarily strict -- for THEIR product
[Of course, the product you now have would be neither
theirs NOR the original manufacturer's]

Of course. It's one thing when I saved broken VCR's for their
parts. I already owned them and they don't take up much room. (Though
when I needed a Zenith head motor, I couldn't find one. Neither could
the shop I used to go to in his stock. )
