Currently the grill heats as
usual, the fan blows and the turntable rotates but neither the

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!).
