Rotu is right - it certainly could be crud on the waveguide vcover or waveguide. If not, it might very well be be a bad magnetron. My understanding is that GE had a run of bad magnetrons and/or other problems in the high voltage section, but I don't know if they publicly acknowledged it. If it's not a dirty waveguide problem, I would contact GE or an authorized servicer. If you don't have a manual, you can download it here: http://www.geappliances.com/service_and_support/literature/

Q - The microwave display counts down and the inside light is on, but nothing is heating and the fan is not running.
A - This most commonly is a bad door switch, other possible problems are a faulty relay or solder joint on the power module, but a bad door switch is most common.
Q - My microwave is running and sounds like it is working but will not heat up anything.
A - Many thing can do this but, common things are....loose high voltage wire.....poor solder joint on board.....magnetron.....power relay.....
Q - The microwave makes a loud "hum or buzz" noise but will not heat up the food?
A - 9 times out of 10 this is usually this is a bad magnetron, the other time is sometimes a bad high voltage diode. See components section.

if you open the cupboard door above the microwave you should see two or four screws/bolts holding the microwave up there. there should also be an electrical outlet up there where the microwave is plugged in. have at least two strong people. put some blankets on your stove top to protect it. unplug and remove the screws. it should be connected in back by a metal plate also. when the microwave is tilted down at a fourty five degree angle, you can give a little lift and it should pop off the plate in back. it is heavy. get a new one at sears or other appliance retail outlets. i dont recommend best buy. they really screwed me over so i dont send business their way.
