It sounds like instead of an overheated magnetron thermostat tripping the power, you now have a defective door switch.
Our door switch help file is here.
There
should be a "mini-manual" (tech sheet) hidden inside the unit
behind the
control panel or hidden on the left side behind the grille, which is
very helpful when troubleshooting, testing, and locating
components.
At
our Web site, we have a video
available showing how to remove a typical
over the range control panel assembly in under 5 minutes.

exploded view diagrams and order parts by entering your full model

SOURCE: GE JVM1870 Spacemaker Microwave Fan Malfunctioning when Cooking
There are two different fans in this model, as with almost all over the range microwaves.
One is the hood vent exhaust fan, which you can turn on and off at will, and which should always be on when cooking on the stove top.
This fan does not automatically come on when you cook with the microwave.
The fan which should always be on (automatically) when you are microwaving is the internal magnetron cooling fan.
If the cooling fan fails, the magnetron can overheat and the thermal cutout (TCO) / thermostat will open, killing the power to the oven. Ideally, this protects the magnetron from being destroyed.
If the thermal device is a thermostat, it will reset when it cools down, and the oven will work.
If the thermal device is a true thermal fuse, it is a one-time device and if it blows, it will have to be replaced.
If your cooling fan is bad, it needs to be replaced before using the microwave.

More than likely the magnetron has failed. This could be for a number of reason. Do you use your microwave to heat wheat packs or warm plates? If so, you may have dried the magnetron out (they use the moisture in whatever you're cooking to heat it, and plates/wheat bags have no moisture).
I'd say a trip to your local Microwave repairer could be in order. It could also be the High Voltage Fuse which has failed. Either way a repairer will be able to tell you!
If you just put the fan blade back on, it will almost certainly fall off again.
The best bet is to slightly rough up the contact area of the shaft with sandpaper and use a little super glue to hold the blade assembly on the shaft, and let it set a few minutes before using it.
I always recommend that you use the hood vent exhaust fan when cooking on the stove top to keep heat, steam, and
grease out of the controls.

OOPS!
I meant to post that as a solution, not a clarification request, so it came out as one big blob paragraph (Thanks, FiyXa!)
Here it is again, but in readable form:
You have a failing membrane keypad.
If you (or someone you
know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically
involved.
It is part number WB27X10171 and while GE sells it for a whopping $115.50, you can get it for $90.58 here.
You can also find
helpful exploded view diagrams via that link.

If you would like to
have us
do this repair for you, we do that for $39.95 plus part costs, in this case $90.58 plus $8.95 shipping for a total of $139.48.
