Buzzing noise, wont work???

The microwave oven no longer works. If the door is opened there is a loud buzzing noise that wont stop util the door is closed. When the buttons are pressed the "beep" sounds weak. Also, if the top vent manages to open, as it normaly should when the oven is running, the buzzing will not stop until the vent flap closes again; it moves really slow and sometimes will not close at all, i have to push the motor so that the vent can close and the buzzing noise can stop. The light insise is dim.

I suspect that it is lossing power somehow.

I have dissconnected & connected several times. No results.

I have not opened the oven, but the noise seems to be coming from directly behind the clock/time display.

    This is exactly the same problem that I have, to the letter. I just happened a 15 minutes ago and I am dreading having to replace any one of the diode, the capacitor or the magnetron. These are the components that I saw online as being able to cause a buzzing noise in a faulty microwave.

The magnatron is shorting, overloading the high voltage transformer. From the picture this looks like an older unit and is probably not worth a magnatron replacement.

Loud buzzing noise with Whirpool microwave oven when it comes on. All lights, heating and fan seems to work but not sure why loud buzzing. What is the problem?


The loud buzzing you hear is the sound of the magnatron tube.That is what emits the microwave radiation and buzzing should be normal. The mag tube may be nearing its end at witch time you will hear no buzzing and hence no heating of foods. Replacement can be costly depending on the model so most people just opt for a new one. Hope this helps

hello Frank. Sorry to tell you that the magnetron is going bad and making that terrible noise. Since the inside of a microwave, even unplugged has up to 2000 residual and deadly volts of electricity I recommend either calling a pro or replacing the unit.
