Resolved Question:

We have a Whirlpool Gold, Model GH7145XFQ-1 MICROWAVE with fan on the underside. When we turn it on it makes a very loud humming noise and and smells like something burning. The microwave is clean inside. The interior light comes on when we press the start so know electricity is ok. The turntable also goes around ok. The noise is very loud and almost feels as if something is vibrating. Please let us know what you think?

Okay the high voltage diode has failed,this part however is very dangerous to replace because it's on the high-voltage capacitor and even with the microwave unplugged this capacitor can hold a lethal amount of voltage, the part is only $9.50 and should be replaced by a qualified microwave technician, be safe and call for a technician to replace it for you, at least you know what it is and how much it's going to run for the part, thanks and best wishes, Bryan
