Most likely a shorted capacitor is causing the fuse to blow. Easy and cheap to fix.

You have a bad secondary interlock (lower door switch) or its mount is damaged or out of alignment.
We have the service manual for this model and have uploaded it to our site here to help you.
You will need the free Acrobat Reader to view or print it in case you don't have it.
Even though a door switch clicks, it may still be bad inside.
Door switch or mount trouble is usually 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. This tab can be hard to see, since it is under the bottom edge of the switch.
If you only need a switch, you can order a universal type here for $5 postpaid.
We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Okay, first we need to separate the situations. You were boiling water on the stove and had the range hood fan running to **** up the steam. Then you put something in the microwave to heat and you heard a pop and then zip-o.
The water on the stove has nothing to do with the situation, the fan you turn on is not part of the microwave, so it has nothing to do with the microwave.
The pop you heard and then the humming suggests the magnetron failed. You said you found a blow fuse and replaced it and still nothing, right? The magnetron is the most likely culprit...I would think it is safe to say that the magnetron shorted and drew enough current to blow the fuse.
Replace the magnetron and if that doesn't work, let me know here. Good Luck!
