The microwave stopped heating anything less than one minute. At the one minute mark, the fan gets quieter, and the microwave seems to increase its power because the light inside gets dimmer, then it begins to heat. So now, no matter what we heat, we must add 1 minute to the time. As an example, yesterday I was trying to soften some icing for on cinnamon buns, which is normally done in 8 seconds. I had to heat it for 1 minute and 8 seconds.

Chances are you have a magnetron that's failing. GE had a rash of "underperforming" magnetrons on these units. They replace the magnetron, stirrer and high-voltage diode at no charge for parts as long as a GE-authorized service center does the work. Sometimes the unit gets run too long in a failing state and the waveguide and chassis of the oven get damaged. The bulletin shows you where tyo check. To see if yours is covered, see this bulletin: http://www.microwavedisplay.com/ge_mw_mag_kit_bulletin.pdf Otherwise, you need to contact GE Customer Relations at 1-800-386-1215 as soon as possible and tell them your problem and they will put you in touch with a local authorized servicer.

Hi , open the cover with philips screw driver , b sure unplug it first , If you have continuety tester check the fuse if open replace it , are available in electronics center brings that sample and insert it.
SOURCE: oven won't heat and shuts down after approx. 20 seconds
If
it stops after 22 seconds, that means the controller has detected a
problem, usually a problem with the inverter or a bad magnetron.
Due to the lethal
voltages used and produced in inverters, I do not recommend that an
inexperienced person work on these.
You can find an authorized Panasonic servicer here.

SOURCE: F2 code on display - microwave does not heat
F2 on this model means you have a shorting
membrane keypad.
If and when an oven is coming on or doing anything by itself, this is very dangerous and can result in a fire.
So until it is repaired,
please leave it unplugged or leave the door
open when it's not in use, and please do not leave it running
unattended.
On this model, the membrane keypad is available already mounted on a new control
panel frame. It runs a little more, but saves a lot of time consuming and aggravating work.
In this case, you simply
move your circuit board into the new frame.
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.
Then you remove a few more screws and disconnect the wires.
It is part # AP3673562 (same as 8205018) and runs $80.97 + shipping here.

For anyone else out there that may have this same problem, I have discovered the solution. Apparently this microwave heats at a higher level for the first minute, and there is a fuse that handles this. I had a repairman come out to fix it and so this fuse ended up costing me $100. We actually had to take the microwave off the wall, then take about 30 screws out to take the cover off the microwave. Then on the right side behind the control panel wall is the 20A fuse which was fried. Do not confuse this fuse with the one that is directly behind the control panel which is accessible without taking the unit off the wall. This one isn't that easy to get too. The repairman replaced this fuse and the microwave starting heating during that first minute again, so all is well now. I hope this helps someone else before they have to spend $100 for a fuse.
