You probably have a defective door switch, or a bad relay. You are not being microwaved. It would blow its internal fuse to prevent that from happening.
If you need further help, I’m available over the phone at https://www.6ya.com/expert/david_29ad5d1dd86564b0
On model JVM1790 / PVM1790, if the cooling fan comes on when you open the door, you have a shorted fan relay on the control board.
I can repair your board for $54.95, which includes insured return shipping. See my link below or e-mail me for full information or other free help.

Thanks for the photo of the label!
It shows the FCC ID number, which I used to find schematics at the FCC Web site.
The problem is a shorted primary interlock switch.
This is the door switch which has two black wires connected to one terminal and a black and a blue wire connected to the other
terminal.

If
it goes dead or blows the breaker or GFI when you plug it in or open or close
the door, then there's a problem with a door switch or door switch
mount.
Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.
Door
switch or mount trouble can be caused by slamming the door or by
opening the door while it's cooking without hitting the Stop pad first.
There
are plastic mounts inside the microwave which hold the door switches
and onto which the door latches lock when you close the door.
The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.
Sometimes
it's a broken tab on the switch holder, allowing the switch to rotate
just out of position. Other times, it's a broken tab on the switch
holder, allowing the switch to rotate just out of position. This tab
can be hard to see, since it is under the bottom edge of the switch.
If
you or someone you know decide to look into it, we have critical
information on safety, disassembly and door switches at our site, and
our link is at our listing here on FixYa:.

There may also
be a "mini-manual" hidden inside the unit behind the control panel or
hidden on the left side behind the grille, which is very helpful when
troubleshooting & testing.

Looking at the schematic in the service manual here, I would say relay RY6 on the small sub PCB (relay board) has shorted contacts.
That's the relay that runs both the fan and turntable.
It's possible that it may be a bad connection or driving component on that board, but in my experience, it's virtually always a stuck relay.
The part number on the relay as shown in the photo is hard to read, but it looks like "OJ-SH-112LM".
I should have one of these or I can point you to one if you want to contact me with the exact number.
Feel free to contact me directly (and please remind me of your
full model number) for more information & help.

Good way to cook yourself! It has to be a stuck door interlock switch--the case needs to be removed to get at the switch. It could be either the mechanism that operates the switch or the switch itself is bad. The switch normally makes a click when the button is pressed. Unplug the unit when the case is removed.

Sounds like there is a stray piece of wire or other metal floating around inside the case. Remove the cover and any breakables in the microwave (the power cord is unplugged for this), turn it upside down over a table and shake it, pound the bottom, and shake it some more--likely the offending piece will drop out onto the table. If so, put it back together and whack it to see if that fixed the problem (cord plugged back in). This process can be repeated.
Hi
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. You should check the internal door switches, the high voltage circuitry and the circuit board for this kind of problems. But for that you will need a certified technician to help you make these repairs.
