A microwave can be dead for many reasons.
If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.
Then when it cools, it closes the circuit and allows power through again.
If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.
You should do a continuity test the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again.
If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.
If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.
If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.
If it goes dead or blows the breaker when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.
If the fuse is good, it may be an open thermostat or thermal cutout on or near the magnetron or on top of the cavity / body of the oven.
If it has a hood thermostat, that should read open, as opposed to the others, which should read closed.
If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk
You can usually find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383
There should also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting.

We have
the service manual for this model and have uploaded it to our
site here to help you.

A microwave can be dead
for many reasons.
It
may be the fuse, which is usually located behind the grille, on
the
floor of the oven behind the control panel, between the door switches,
or on the filter board near where the cord comes into the unit.
If
the fuse is good, it may be an open thermostat or thermal cutout (TCO)
/ thermal fuse on or near the magnetron or on top of the cavity / body
of the oven.
If it goes dead for a
while during or after cooking
then comes back on, the magnetron is probably overheating and causing
the magnetron thermostat to open.
Then when it cools, it
closes the circuit and allows power through again.
When
checking TCOs or thermostats, if it has a hood fan thermostat,
that should read
open, as opposed to the others, which should read closed.
So don't let that fool you.
If the cavity thermostat
needs to be checked or replaced you'll need to pull 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.
If it went dead almost
immediately after pressing the Start pad, that's usually a shorted
high-voltage capacitor.
If it went dead a few
seconds after pressing the Start pad, that's usually a failing
high-voltage transformer.
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.
If it's intermittent or
random, it may be a bad
connection, usually on the control board or a loose fuse holder, or
even an intermittent fuse.
You should do a
continuity test on
the fuse while it's in the holder (with the microwave unplugged, of
course) then turn the fuse by hand or take it out and put it back in,
then test it again.
If you remove the fuse,
then press the meter
leads against the ends, it can allow internal contact to be made and
make a bad fuse appear to be good.

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.

This is almost certainly a blown thermistor. This device is located at the air outlet on the microwave. This is a thermally sensitive resistor that cuts power if the unit overheats for safety. It can fail because of age also. Replace with the save value unit. You can get this part from electronics stores like Radio Shack.

Chances are that either the diode or capacitor are shorted. Be very careful, the capacitor can store a charge and should be discharged first for safety. Hope that helps...
