I just tested my microwave diode where, unfortunately, it

good:

Forward biased with a 9 VDC battery, I measure 7 VDC
across the diode;
reverse biased, I read 9 VDC across the diode (given a 200
ohm
current-limiting resistance in series with the battery).

I was hoping the diode was bad, because otherwise, I don't
know what's
wrong with the microwave. It does everything but heat up
the food.

It makes noise, the lights light up fine, the controls all
work,
and it beeps when done, etc. - but it just won't heat up
anything.

Did I test the diode properly?

if it does everything but heat it might be the magnatron
