Question about Microwave Ovens
I have a GE Profile Spacemaker 2.0 Microwave Model JVM2070BH002 manufactured in February 05. Recently, it seems that the control panel where you enter the cook time, etc. has been shorting out. One time, it reset to all 0000's and every light on the panel was lit up. This morning, I put a cup of coffee in it to warm, it started fine but shut off after about 2 seconds. I tried it again and same thing happened. Any idea what the problem could be? Any help would be greatly appreciated.
Clean the inside top of the microwave. There is food stuck to the top and is killing your microwave cook time. I had this same problem and was fixed $125.00 Later. Good luck

How do you get to the digital display on that model? Are the screws under the microwave on the side of the display? or next to the display when you open the door? I have screws in both places...

WARNING: The "technique" of using "anti-static paper" or anything else to try to
shield the control circuit board is not a fix, but a band-aid at best...
This problem is almost always due to a defective or loose magnetron causing electrical interference and disruption in the control circuit board.
The shielding may keep the interference out of the controls, but it's still being emitted, and the magnetron will eventually go bad.
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@example.com
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.
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.
You can find helpful exploded view diagrams and order parts by entering your full model number here.
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.
If it is not within the magnetron warranty, you can find helpful exploded view diagrams and order parts by entering your full model number here.

Hey, "timebomb" thanks for that comment but there is absolutely no food stuck there but we did fix it using another persons comments. We went to a local computer repair store and they GAVE us that anti static paper for FREE and we opened up the digital display and covered the inside back portion with the paper that I mentioned and IT TOTALLY WORKED our microwave has been working perfect now since we fixed it on like January 3rd, 2008. We are shocked!!!!!!! Boy, my interned bill paid for itself this month because after doing research we knew that it was going to end up needed a new magnatron plus labor costs, I would have hated to see that bill. WHAT A JOKE, GE definitely knows that this is happening. They SUCK!!!
