Question about Sharp R-530ES Microwave Oven
The loud "hum" together with the burning smell usually indicates a bad Diode (attached to the High Voltage Capacitor-about the size of the cap on a pen.) Many times you will see where it has burned, and in a few instances disintegrated, and you will certainly smell the pugnant burned odor on the Diode. Easy to replace, and a low cost part.

This can be caused by grease etc. inside
the oven and on the wave guide which is the paper like thing in the oven. If
you can remove it look for burnt areas which may can be scraped off or you may
need to replace it. An appliance parts store usually has the material you can
cut to fit you own.
