If it's unplugged, have fun. Don't try to put it back together and use it though. There's a lot of high voltage stuff in there to run the magnetron and the seals are pretty critical for safety. By the way, the capacitor has a bleeder resistor in it to drain the charge.

Yes it is.
If you don't know what you are doing then only take a microwave apart to change one of the fuses. You must make sure that you get the correct fuse replacement. If the fuse blows again then get a professional to fix it.
The main hazard is the power supply which has extremely dangerous voltages, something like 2500 Volts DC at low impedance. There should be a resistor that discharges this after you switch off but this may take a minute to dissipate the charge. Much longer if the resistor is broken so you need to short out the capacitor first if you are thinking of touching it.
If you disturb the magnetron or defeat the safety interlocks you may start emitting microwaves. This can cook your eyeballs in seconds.

Not at all, as long as it is diconnected from the power suplly, and a bit of wire then between live & earth will dicharge any residual voltage within.
Please don't fiddle too much with the "'tron" that generates the waves, though. that's the bit that looks like a small discus thing, housed inside, on the side, and needs to be in good position.
Also the door seals - perfest replacement is called for.
If it just an internal fuse problem, which I doubt, as the one in the plug is normally the last line of defence, then by all means bung in a new one of the correct value.
Then just for fun, bung in three fresh eggs, and get folks to bet on which one goes pop, in a big internal mess, first.
It is not usually dangerous to dismantle most bombs, if the thing is dis-armed first.
All the best with it & take care!

Yes if the HV capacitors bleed resistor is open circuit it can retain a very high voltage,several thousand volts in fact.When I was in the service industry engineers were not allowed to tackle microwave repairs until we had passed a Sharp repair course which was the industry standard at the time.You should under no circumstances take the main casing off whether its connected to the mains or not.

As long as it is un-plugged, there should be no problem. When plugged in and operating, the supply produces about 2700 volts and enough amperage to kill you. When shut off, an internal resistor in the high voltage capacitor slowly discharges it. Safe to open, check fuse and connecting clips. I don't recommend any live troubleshooting. Too dangerous without proper training / experience.

yes it is, apparently they contain a capacitor which contains enough charge to kill you with the electric shock. This is true even after the microwave has been unplugged and I suspect it remains dangerous for a long time. Its best to get an expert to do that job.

only if the power is on. isolate from the power and dismantle the equipment. only one piece of advice - after you have reassembled switching on can be risky. use professionals for these kind of jobs.

yea, but good craic. i suggest making a microwave gun with it.

Only if your cooking somthing in it

its safe to do that so far it's not plugged to the mains
