Microwave trips breaker

All of a sudden our microwave trips a breaker the instant you plug it in. We’ve tried different outlets on different circuits and it does the same thing, so I suspect the microwave is the culprit. I’m told it could be either an internal fuse or the magnetron. If the latter, I would just replace the microwave due to cost of the part.
How can I further diagnose which it might be so that I can not waste money on a service call, if it turn out to be the magnetron? Any ideas?
One odd observation: I think the screen has been dim the last few weeks leading up to this and is related. The microwave tripped a breaker for the first time yesterday. I corrected some iffy wiring connections and plugged back in. Microwave worked overnight with the screen bright again. Today, it trips any circuit breaker I plug it into. Tia.

Well it's not the fuse and apparently not the outlet.
Just leaves the microwave....

Ours did same thing, replaced the door catch switch.
It's a normal open switch so when it fails its shorts out the system.

Take it apart
Unplug the magnetron, diode, transformer, and control switches. There’s a heat, light, moisture, and a couple door interlock switches. Start plugging them back in starting from the primary, one at a time. Plug it in each time you add something. When it starts tripping again you have identified your problem.

Before replacing the microwave, bang the shite out of it. Slam the door a few times.
Seriously. Over the years I've found a very useful tool is to bang something hard before giving up.
There might simply be something like a crumb or something hanging up somewhere.
Try it. Guaranteed to work 100% of the time, almost every time.

Not to beat a dead horse, but it seems that you should just buy a new microwave. If it's several years old, it wouldn't hurt to get a new one. Most of the time the parts to replace will cost so much that a new unit would be better purchase.
