I don’t remember if it was always was like, this but this happened to me with two different microwaves in two different houses. It mostly happens when touch the top of the microwave, but it can happen with the door too.
I though that it was just something unavoidable with microwaves and didn’t mention it to anyone, but today i decided to tell my mom and, she said never had any microwave electrocute, same goes for my sisters.
My little sister did comment that i have high energy(what they call my ADHD) as the probable causes. I don’t really that possible but i have discovered weird things about my biology before(e.g if i leave my computer screen on in my room, i can feel its heat even under the blanket and cant sleep).
Update: I still do not know why i get shocked while my doesn’t. I told my sister to touch the mirror door and she didn’t feel anything, then i put my hand next to hers and we both get shocked. I have a theory that’s its cuz i am very hairy? Either way, i am told there are lot of possible causes
Shocked, not electrocuted. Electrocuted is being fatally shocked.
Your microwave probably uses a grounded plug. If this is the US, it’ll look like this:
That third, rounded pin is the ground pin.
When devices have grounded plugs, the case is normally connected to the ground pin.
If you’ve built up a charge, touching something grounded will discharge it.
You might get it in a dry environment, where it’s easier to build up a charge, like if it’s an air-conditioned house or cold and dry.
As to avoiding it…
If it bugs you, it sounds like there are shoes that people wear for jobs where having static electricity buildup is problematic, that have soles made out of more-conductive material than the typical insulating stuff we use, that keeps charge from accruing by letting it slowly discharge into the surface that they’re standing on. Might try them.

Or just going barefoot around the house.
