SOURCE: dead microwave
There are replacable fuses inside. Taking the microwave apart requires removal of a lot of screws and the cover that can be rather bulky. make sure it's unplugged and safe before you begin. you can get replacement fuses at radio shack, ect. be sure to buy the same type and amperage. if the blow a second time there may be other issues.

You can test safety thermostats with an ohmmeter. There should be a short circuit between the device's two terminals if it's closed. (This doesn't necessarily mean the device is good, though. It might be opening at too low a temperature when the oven is operating.) A high resistance or an open circuit means the thermostat has opened and needs to be replaced. An appliance parts store should have suitable replacements, or you can order from a number of online vendors. I usually start at the Sears parts site. They have part information for many models, and usually pretty fair prices for parts. But once you have the part number you need, a Google search will let you shop around.
It does sound like your oven shut down because of a thermostat. One is normally mounted on the magnetron tube that supplies the microwaves, and another is on the cooking cavity. I've had to replace these many times. If the main power fuse blows the oven will not come back on until it's replaced. But you might also have bad solder connections causing the trouble as well. I've seen solder joints on the control board and power filter board cause dead ovens.
If you're not absolutely sure of what you're doing working on a microwave, you might want to let a professional check it over and make an estimate. There are potentially lethal voltages present, and microwave leakage may be a concern as well.

Chances are that the thermostat / thermal cutout / T.C.O. (whichever it uses) has opened.
This can happen when the magnetron overheats, either due to it's failing, or if the internal cooling fan is not working.
It may also that be the 15- or 20A ceramic line fuse or the oven cavity thermostat / thermal cutout / T.C.O. (whichever it uses) has opened.
There should 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.
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.
You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.
You should be able to get the fuse from a home center or local appliance parts store.
Accessing some components for testing and possible replacement will require you to remove the oven from the wall.
If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.
You can download GE owner's manuals and installation instructions here.

change the units internal ceramic fuse and try this,may just be a fuse or if new one blows then could be h.v. diode.capacitor,thermal fuse,magnetron tube

NO internal fuse. It is most likely, the magnetron, and or High power diode. As related In all likelihood the mangnetron has failed, or perhaps even the Power Supply. or a fault that is shutting the system down for safety reasons You need to have it serviced by a reputable service centre/man. Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.
