Model number NN-V659 has gone kaput. The instructions say it must only

is it just a safety matter?

As another poster has said, microwaves and combination ovens contain a
large high voltage capacitor; usually in a metal can with push-fit
terminals and with an internal bleed resistor, which could perhaps fail
unless the dielectric material itself is the resistor (by being
intentionally just a little bit electrically leaky; don't know if they
could do that with modern materials but it would be a clever way to
make the thing safer).

Neat idea


Changing the bulb is not much more difficult than changing an ordinary
light bulb. Some replacements may have been designed to withstand a bit
of vibration, I've heard, so you want the correct bulb.

True, and combi oven bulbs are higher temp rated too. But in practice
I've found generic candle etc bulbs work fine. They might not last so
well if you're in the habit of thumping the machine.
