    Sorry, I meant to ask if it's MV-1650ST?

    Is your model number actually MV-150ST?

    I'd suspect the magnetron or high voltage diode, but please reply back with
    your brand and full model number from the tag so we can help you
    properly.

Kenmore Over the Range Microwave making buzzing sound and not heating


This is a strong indicator the magnetron is fried, also! this is the most expensive part to replace in the microwave oven, and in most cases cheaper to replace the whole unit.

My GE Space Saver Microwave that comes on but makes a buzz sound in operation and does not heat.


If it buzzes before you hit "Start", you may have a control circuit board problem or a door switch problem.

If it buzzes after you hit "Start", you would probably have a bad magnetron and/or high voltage rectifier diode.

We would need more details no the failure and of course the full model number to help you further.

My microwave no longer heats anything and also makes a really loud buzzing sound when i attempt to use it.


The problem is most likely caused by a defective magnetron that "heats the food" is loading down the high voltage transformer causing it to make a loud buzzing sound. The cost to repair (depending on make and model) will probably approach the cost of a new microwave oven when you factor parts and labor.

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.

Works but no heat or cooking


Hi


Thanks for using FixYa. Microwave not heating properly is caused by a power relay going bad, cold solder joint on the board and/or magnetron (this is only if it makes a loud hum/buzz sound). Also the door hooks and the door-release button should be checked. Please do rate the solution if the issue is resolved or post a comment for further assistance.



Thanks

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

Microwave makes loud buzzing sound when on and no heat


Have you tried putting a cup of water in it and cooking on a low power level? If it buzzes only when it is on the cook cycle, that would narrow it down. More detals might help us help you, including the model number.
