Over the cooking range.
From the description a major part has failed, the magnetron is suspect because it suddenly shut down in cycle, if the unit is less than 7 years old it probably has a inverter board and tends to fail, also there is the possibility the keypad control board has stopped working. The microwave in my opinion is worth getting checked out and repaired, but it will be expensive.

The problem you are having with your microwave is a common one. Not heating is a problem that can be caused by three things. I'll list the most common solution first, the magnetron that actually does the heating is what is making that noise and has gone bad. It is possible for you to also have a bad high voltage diode that has opened up, solution two, or solution three is the high voltage capacitor is not working properly as well. From my experience with microwaves I am positive that it is your magnetron that is bad. If you are not do it yourselfer you'll need to take it to a repair shop to replace. However, if you know how to use a screwdriver and can unplug a couple of wires with spade terminals on them, then you can take it off yourself, find another one and replace it the same way you took it off. The magnetron sits behind the control panel of your microwave but on top. It has cooling fins on it and has 2 terminals maybe three depending and make and model that plug into it. It has 4 screws that are easy to get to that actually holds it in place. If you do not have a good local source like an electronic parts supply place then you can find the right magnetron at www.mwoparts.com. Be sure you always unplug the microwave before touching or trying to take the he cover off and then when you take the magnetron off also.Good luck and God bless.
SOURCE: GE Eterna Microwave stops after a few seconds, must reset clock..
The
first thing I would suggest is a hard
reset. Unplug the unit for a
minute or so. Then plug it back in, set the clock and try again.
If that doesn't work,
leave it unplugged for about 5 minutes.
Otherwise, this
is almost always due to a defective or loose magnetron causing
electrical
interference and disruption in the control circuit board.
Details covering some previous
models are in
their bulletin here. Even if your model is not on
the list, the same problem can occur.
If
your magnetron was recently replaced, it may have loose mounting nuts
or bolts or maybe the wire mesh RF gasket was not installed or got
pinched.
NOISY MAGNETRON TEST (c) 2009 William E. Miller [email protected]
(PLEASE do not be fooled into thinking that the procedure outlined at this link is a "fix". It should only be regarded as another test method to prove that you have a noisy magnetron which must be replaced.)
One way to test it is to
do the following:
1. Unplug the microwave
or turn off its breaker.
2. Open the door, then
detach the control panel as shown in the video at http://www.microwavedisplay.com and swing it down, but without
disconnecting the wires.
If you have any trouble getting the grille off once the
screws are
removed, slide the hood vent grille to the left about 1/4", then then
pull it forward. On some models there are L-shaped clips that fit
into a slot to hold bottom of the vent.
3. Plug the microwave
back in.
4. Make sure neither you
nor anyone else reaches in behind the control panel. There will exposed
high-voltage connections.
5. Put a few cups worth of water in a microwave-safe container
and place it inside the microwave.
6. Shut the door.
7. Run the microwave for
about 1 minute or so on full power. (Time Cook > 1 > 0
> 0 > Start, e.g.)
8. If it does not fail,
try it several more times.
9. When the water boils, change the water and try again.
NOTE:
If your model does not have a door handle, you will need to unplug the
oven and reattach the control panel to be able to open the door.
If
it still does not fail, I would recommend that you put it all back
together and keep using it until it fails more consistently, then
repeat this test.
If it keeps failing while the board is in the down position, you either have a very leaky magnetron or possibly another problem.
So you can then get a Ziploc bag and insert a flat piece of aluminum foil into the Ziploc and close it.
Then
(with the power off) tape it over the circuit board as best
you can, covering it as much as you can, making sure it does not get snagged or punctured.
Then try the oven again. Do not leave this test shield in place as a "fix". It is not safe.
While
a microwave should never be left
running unattended under any circumstances (as your owner's manual will
tell
you) it's even more important when one is exhibiting a failure or any
odd behavior.
So play it safe and stay with it while it's running!
If
you or someone you know want to replace the magnetron yourself, you
will need 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.
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.

If
it's within the magnetron portion of the warranty (usually 5-9 years)
but out of the original full warranty (usually 1 year), then your
manufacturer will cover the part cost, but not the cost to visit you or
the labor charge to do the work.
Sometimes they will
send you the magnetron to do it yourself. Call them at 888-239-6832.
Be persistent. You may have to speak with a supervisor.

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

You should be able to

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.

Sorry my Clarification Request came out as a single blob of a paragraph.
That's not how I typed it. I never write that way!
So I've pasted it here, but as a solution.
Magnetrons generally should last about 2000 hours, but several factors can shorten that.
If it's not OVER ten years old (from the purchase date or the date on the tag inside the unit) then the magnetron is still under warranty.
From the owner's manual:
"For the second through the tenth year from the date of original purchase
"The magnetron tube, if the magnetron tube fails due to a defect in
materials or workmanship. During this nine-year limited warranty, you
will be responsible for any labor or in-home service costs.
"For the above limited warranty: To avoid any trip charges, you must take the microwave oven to a
General Electric Customer Care® servicer and pick it up following service. In-home service is also
available, but you must pay for the service technician’s travel costs to your home."
GE Customer Service is here, and you can verify the warranty status and find your nearest authorized servicer.
If you're sure the magnetron's bad, it's still under warranty, and you or a friend are handy, they will
send you the magnetron to do it yourself. Call them at 888-239-6832.
Be persistent. You may have to speak with a supervisor.
It does sound like the magnetron overheated and the magnetron's thermostat opened until it cooled down.
An overheating magnetron can be due to:
Since yours is a counter top model, there are less of those factors to worry about.
When you hit Start to
microwave, do the inside light, cooling fan, and turntable all come on?
Any unusual noises? Is
it louder or quieter than usual?
We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here.
