One of the high voltage components has failed, and my suspects (in order) are the high voltage transformer, magnetron, or possibly the high voltage diode.

You can probably replace this oven for less than $150 now, so it may not be economical to take to the shop.

If you or someone you know wants to look into a self-repair, we have *critical* safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

You can probably find an exploded view and order parts by entering your model number here. Sharp parts are usually less expensive here.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

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.

Microwave makes a loud buzzing noise and emits a burning plastic smell


This indicates the magnetron has failed, buzzing sound and odor are classic symptoms. It is cheaper to replace than have it repaired.

I have Danby microwave, the food does not heat and there is smells like some thing is burnt. I have opened it and the high voltage transformer does not look burnt.


What is happening is that the magnetron is shorted, causing the high voltage transformer to overheat. That is what you are smelling is the insulation getting hot. When the magnetron shorts out, it makes a loud buzzing sound. Replacement magnetrons costs almost as much as a new oven so it rarely makes sense to fix.

Heat element not working


Well, if there is not heating the food and making a loud buzzing or humming sound when it is on, then the magnetron has failed. It typically shorts out and fails. The magnetron for this cost $140 plus the cost of the service call, you're better off buying a new oven. Hope this helps.

Making loud buzzing sound & smells like wires burning.


That is the Magnatron or the Hi-Voltage transformer. If I could smell it I could tell the difference. The transformer will produce smoke more so than the Mag.

Not working plmv169dc


HI, the sound you herd was the noise filter and running diode. these important components have failed at this point. you will need to replace these components asap, if possible. this will fix your issue.

The Magnetron Cut-off fuse will need to be replace as well. this will blow if there is a malfunction within the unit.

Makes a loud buzzing noise and does not get hot


Have seen this many times.

Sounds like a bad CAP since a bad diode would blow the fuse and a bad mag would likely do the same thing.

Since yours is making the loud 60hz buzz you need to replace the capacator that will likely fix the problem. A $10 fix

No Power at all after loud short buzzing sound


sounds Like an electrical fault in the Micro, Sorry but this is broken.... If this is within warranty (do check as some warrantys are for 3 yrs or more) get the manufacturer to replace/repair it for free. you could get it serviced, but it is probably cheaper to buy a new one.
