Re: Everything works but "heating".
Makes grinding
The loud buzzing sound with no heating, is symptom that the magnetron has failed in your oven. Magnetron replacement cost are almost as much as new oven, so it does not make financial sense to repair. Sorry.

The magnetron won't make a grinding noise so that makes it sound like the fan motor bearings are bad. However if it doesn't heat, that sounds like the magnetron.
UN -PLUG IT,,,,, THAT "FUNNY SMELL" SOUNDS LIKE IT IS SHORTING OUT
PERHAPS THE MEGATRON HAS GONE BAD, THE MEGATRON IS THE
HEART OF ANY MICROWAVE
AS A EX- FIREMAN, I KNOW FROM FIRST HAND EXPERIENCE THAT
"A FUNNY SMELL " OR " UN-USUALL SMELL COMING FROM AN ELECTRICAL
ITEM IS A SIGN OF DANGER
Sounds like you burned out the magnetron, if so you should discontinue use immediately. This is the bit that emits the microwaves and they will fail with a burnt faintly oily smell to an acrid chemical smell. Magneton replacement should not be attempted by the amateur fix-it man, Find a reputable appliance repair shop or chuck it in!
hello kmwnky,
You say that Everything went out at first ( which I assume means that all functions went dead) and then functions started to operate again later... if that is correct and you smelled something burning.. you may have a thermal fuse that failed, filament transformer that failed, magnetron tube that failed or a highvoltage capacitor that failed.. None of these components are something the untrained person should attempt to trouble shoot or replace since there are dangerous energies stored inside the electronics compartment even after power is removed.. Your Micro is > 8 years old and it's probably not worth the cost of repairing at this point. You'd be better served replacing it.. The cost to repair would exceed the cost to replace.. ( I feel like the grim reaper here..sorry..)
Regards,
Rick
