Typically the buzzing sound will be caused by a bad diode but if you have a bad diode it will not heat.

What can happen is the magnetron tube can arc causing a noise but sill heat then eventually stop heating.
If the diode is bad you need to change the magnetron tube and the diode.
The noise and the heating problem may be separate issues.

I think your magnetron tube needs replacing.
