My microwave oven has burned out, it no longer heats up but still consumes 500W: where does the energy go?

[Christophe]

Everything is in the title, where does the energy go from a microwave oven that no longer heats food?
In our pre-cancerous cells?

Indeed, I toasted my microwave oven (the microwave part) this afternoon after several cycles of more than 10 minutes .... everything else works but no longer the microwave heating part and yet it still consumes in the 500W ...he was 15...

Rest in peace !

Buy a wave sachet?

You have to be careful, there is a part in there that is dangerous if not protected by scrap metal!

[Christophe]

Yes I will change it...but that does not answer the question...where do these 500W ptin go???

[phil59]

The primary of the transformer?

Does it also grill or not? because it could in there, bad contact?

[Christophe]

The transformer of a 600W microwave oven...does not dissipate 500W eh...well, not in normal times...hence my question: where does the energy go???

Yes it grills and yes it still works (at 1000W)!

[phil59]

In electronics, I saw the calculations to change an electron layer, the arsenic to add, etc., but no real editing ....

And it's all a bit old!

[Remundo]

hard to give you a clear answer

but the magnetron: https://fr.wikipedia.org/wiki/Magn%C3%A9tron

even defective in the end, can consume a lot of electrical power

There are of course all the transformers upstream...

[Christophe]

Yes the magnetron is most likely very cooked..

But 500W to dissipate is a lot...

[Remundo]

the magnetron is a thing that excites electrons and loses a lot by radiation.

I wouldn't be shocked if a half-dilapidated magnetron swallowed 500 W.

[Christophe]

Yes precisely 500W lost in radiation... but what kind of radiation?
