No that may well weld the screwdriver to it in any case!

Many do have a high value bleed resistor though, so it does discharge
gradually over time.

When working do they share the same heat source?

No, they are entirely different technologies, different methods to
create heat.

True, but both are "high power". Perhaps there is a 10A fuse or similar in
the "high power" circuitry in the microwave which has blown. However,
fuses usually blow for a reason, and finding that reason could be
difficult. It is also inherently dangerous; even if disconnected from the
mains microwave ovens can retain a high voltage in the magnetron drive
circuitry capacitor for some time. That capacitor would need to be
completely discharged carefully before the OP went digging around inside
for a fault (that does not include putting an insulated screwdriver across
its terminals!).
