Wow! sounds really weird. Possibly Microprocessor on Main Timer board. No way to really diagnose other than substituting or replacing the main board. Unfortunately a bit pricey. Nothing else i can think of that would actually cause asterisks in the display. I really do not like to refer them, but may need to call GE since it is one of their units. Maybe they could give you some guidance. Mostly, over the phone, they just insist on sending someone out. So they can bill you more.

Assuming that your internal cooling fan is working, I would suspect that your magnetron is failing.
You can usually find helpful exploded view diagrams and order parts by entering your full model number here.
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, and locating components.
I would check the cooling fan, then suspect the magnetron.

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.
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.
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.
Feel free to contact me directly (and please remind me of your
full model number from the tag on the unit) for more
information & help.

Sounds like the Magnatron or the HV Cap or diode is failed. Process of will show you which one. Very dangerous area to work in, not for the untrained. Eric

Hi and welcome to FixYa. I am Kelly
When a micrwave quite during use it does have a tendancy to make the user wonder just what happened. There are several components that can cause this symptom.
1. The High Voltage Capacitor
http://www.appliancepartspros.com/partsearch/model.aspx?model_id=5227571&diagram_id=22974428#d22974428
(item 49)
2. The diode in the diode cable has failed
(Item 50 in the link above)
3. An open thermostat (Item 110) of above link (there are 2 of them)
4. A failed Magnatron (Item 73) This is pretty rare that a magnatron fails... It is usually something else.
Since you do not have any lights or appearance of power the fuse is probably blown.
http://www.appliancepartspros.com/partsearch/model.aspx?model_id=5227571&diagram_id=22974429#d22974429
(Item 47)
It can also be the duct thermostat item 27 but again this is a rare failure.
Usually what happens is either the HV Cap or the Diode in the Diode wire fails.
IF you even attempt repair... make sure to short across the HV Cap terminals at least 3 times. The first time if the cap is good it will really make a bang and spark.
To test the diode wire... "unhook / disconnect one end of it and use a meter to read it using resistance. One direction it should read. Reverse the leads and it will appear open.
There are a few other things like interlocks, HV transformer and control panel board that can cause this but again the instances of failure are pretty slim.
Replace the 20A fuse in the fuse holder. IF it blows again either the diode or the Cap is most likely the problem
An informational note... IF someone opened the door slowly without pressing pause / stop it can via the door interlock switch blow the fuse.
Hopefully this give you a clue as to what has happened and what to look for as far as repair and expected expenses.
Thanks for choosing FixYa.

There's a simple fix for this. Unplug the unit. Take off the top grill with 2 screws. Remove the 1 screw that holds the touch pad unit. Lift up on touchpad unit and lift out. Put a piece of aluminum foil inside a large zip lock bag and tape it to the back of the touchpad unit and reassemble. GE put the magnetron to close to the control board causing stray microwaves to interfere with the board. The foil shields it.
