Sounds like the main fuse blew. It's either near where the power cord enters the cabinet, or behind the control panel (if an over the range unit).

You may also have some type of failure in the high voltage circuit; based on your description of the symptoms.

Blown fuse inside of unit. Must find out why fuse blew, something shorted or bad connections.

There is an internal fuse. Be careful high voltages present even if the microwave is unpluged.

Good luck

The microwave oven internal fuse has blown, unplug unit, remove top case 2 to 6 screws, on right side look for a long rectangular silver capacitor, "carefull high voltage" the ceramic fuse should be next to it, "white body with silver ends" remove and replace with same rating. If the fuse blows again chances are the door switch is defective and must be replaced.

from online Microwave Repair Manual: Totally dead oven (no lights, no clock, no display, no fan, no heat...)First, check power to the outlet using a lamp or radio you know works. The fuse or circuit breaker at your service panel may have blown/tripped due to an overload or fault in the microwave oven or some other appliance. You may just have too many appliances plugged into this circuit - microwave ovens are high current appliances and should be on a dedicated circuit if possible. If you attempt to run a heating appliance like a toaster or fryer at the same time, you *will* blow the fuse or trip the circuit breaker. A refrigerator should never be plugged into the same circuit for this reason as well - you really don't want it to be without power because of your popcorn!

If you find the fuse blown or circuit breaker tripped, unplug everything from the circuit to which the microwave is connected (keep in mind that other outlets may be fed from the same circuit). Replace the fuse or reset the circuit breaker. If the same thing happens again, you have a problem with the outlet or other wiring on the same branch circuit. If plugging in the microwave causes the fuse to blow or circuit breaker to trip immediately, there is a short circuit in the power cord or elsewhere.

The microwave oven may be powered from a GFCI outlet or downstream of one and the GFCI may have tripped. (Removing a broken oven lamp has been known to happen.) The GFCI outlet may not be in an obvious location but first check the countertop outlets. The tripped GFCI could be in the garage or almost anywhere else! Pushing the RESET button may be all that's needed.

Next, try to set the clock. With some ovens the screen will be totally blank following a power outage - there may be nothing wrong with it. Furthermore, some ovens will not allow you perform any cooking related actions until the clock is set to a valid time.

Assuming these are not your problems, a fuse has probably blown although a dead controller is a possibility.

While you can do some repairs on your microwave, what you don't know can kill you... even on an unplugged microwave, so make sure you understand the dangers and how to reduce them before you try anything inside a microwave. If you want to do more yourself, go to the link at the top of this post.

Bill,
I have the same unit. It just happened to me. DId you find a resolution?
I was using it on the oven mode and it just stopped working. It's completely dead.
Thanks
Bob

There is a fuse inside the oven. The rating of the fuse may be 8amps. It is not suggested to run the oven without load inside.

Sorry Seanna, but I have been getting a lot of problems with GE microwaves. You can call customer care at 800-432-2737, but out-of-warranty repairs are very expensive. Sounds like your problem may be door latch circuitry which requires service. If your unit is old, consider replacing it as prices are very reasonable.

couple questions -
what else is on the circuit,
and what current does the oven need

there are whirlpool over-range models with
1200watts of microwave,
1500watts of convection power, a
60watt bulb and a
375watt fan

over 15amps -20amp circuit needed

if you inadvertantly replaced a higher current fuse with a 15amp fuse, it will blow every time.
the install guide http://www.whirlpool.com/assets/pdfs/product/ZINSTALL/8206589.pdf reccommends 20amp
not a solution, something to check,
