A microwave can be dead
for many reasons.
It
may be the fuse, which is usually located behind the grille or on the
floor of the oven behind the control panel or between the door switches.
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.
If the cavity thermostat
needs to be checked or replaced you'll need to pull the oven from the
wall, in which case 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 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.
You can usually find
helpful exploded view diagrams by entering your full
model number here. Once you have the part numbers, though, I would suggest ordering parts here at a much lower cost.

A microwave can be dead

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)

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.

SOURCE: GE Profile Microwave will not heat
Unfortunately, there is no way to tell which part the microwave needs without opening it up for examination. There are a few parts that, if defective, would prevent the oven from heating.
This is NOT a repair that you would want to attempt yourself. The labor for the repair would cost a minimum of $50 and shouldn't exceed $100. You'll also have to pay for the necessary part if it's still available from the manufacture or their parts distributor.
