Microwave stopped working, no power. Checked

If you are not sure in ANY way about using this microwave BUY a new one. Simple as that!!
As long there where no sparks, strange noises or strange smells you should be OK to use it. Most modern microwaves have safety electronics built in that can act as a safety switch.
You can buy 'Plug In' adapters that are designed as a safety circuit breaker. Try searching for "Plug through RCD adapter". These 'Trip' if there is a power surge stopping the power to the item plugged into it. I have one for when I use big power tools.

I guess the main plug fuse does not blow for the same reason it does not blow and you can wreck a PC, although not certain why that is. I have a feeling from past work on a Panasonic that there is an internal fuse as well. This may have blown with the power surge.

If it has a turntable does that work or not?

Did you recently have trouble with the cooktop lights?

Sometimes when the cooktop lights blow or are inserted or removed while the oven is still plugged in, the filaments can short, causing a surge that damages the controller.

They can be repaired. More details here.

Inside the external case and usually to the right left ( from Front) in some models There is a 30 amp fuse ( This may vatry on oven output amperage) Replace that and you should be back in cook mode.
Removing the case you should remember to disconnect from the power plug.

Please rate my help++++Thanks for using FIXYA

Hello there:
If you have checked out the fuse and you are 100% sure that it is ok than you will want to have the door switch checked out the door switch completes the electrivcal circuit when the door is closed and if it is bad there will not be any power to the unit at all. so it can give you a faulty indication a lot of people misdiagnose the door switch thinking there is or should be power or lights when the door is open ok ?
And if this still does not work then the next thing to check out after this will be the power inverter ok
Hope this all helps out
Best regards Michael

you need a new hv capacitor and a fuse

Yes check breaker box / fuse box.

If the fuse isn't the problem, check the door hooks and the door-release button. When these are broken, the door switch doesn't activate, so the oven can't work.

Yes, there should be a ceramic (tubular) fuse under the cover on the top side where the power comes into the microwave.
