Hi Toan, first question is how old is the microwave? If it is less than 5 years with no other problems, then yes it's worth fixing. If it's older than 5 years or has other minor problems it might not be worth it. Check the cost of new before fixing and call a repair company in your area to compare prices. Hope that helps.

sounds to me like the magnatron has shorted out. i don't know of a way to test them unless you have some high dollar equipment. a continuity test prob wont tell you anything. what reading did you get on the cap when you tested it?

We have *critical* safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk
There should also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting. It will help you test the keypad with your meter.
You can usually find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383
If you'd rather have us fix it for you, we do that for $39.95 plus parts.
DISCONNECTING THE KEYPAD
1. Be sure the oven is disconnected from the power line while you are taking it apart.
2. The keypad connection is the green or blue translucent plastic strip that plugs into a connector near the edge of the board.
3. There are two tiny tabs (one on each side) of the connector that you can gently pull up on to unlock the connector.
4. Then the keypad strip will lift out. Clean both sides of the end of the strip with alcohol-based cleaner if you like, but do not use ammonia-based cleaner. Dry the end of the strip. (A pencil eraser is better and safer).
5. Put the keypad strip back in, making sure both sides are down fully.
6. While holding the strip down, push the connector back down to lock it.
7. Try the keys again with the door closed.

If some pads on the keypad are not working, then you have a failed 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.

On this model, the cover will have to come off to replace the light bulb. If it's mounted in the wall, it will have to come down.
The installation instructions are nice to have in this case. You can download GE owner's manuals and installation instructions here.
I have attached a drawing to show where the bulb is on this model. It is located on the right side of the oven next to the wall of the cooking cavity.
The bulbs are available in local grocery stores, hardware stores, and stores like Wal-Mart and Lowe's.
Please feel free to contact me directly if you need more help.

The membrane keypad has failed.
The keypad itself is not available as a separate part, so the control panel frame with keypad would have to be replaced.
This is actually a pretty simple DIY job.
You can part number
WB56X10826
from the Pros
here for
$114.62
plus shipping (that compares to
$166.50
from GE!).
You can also find helpful exploded view diagrams at that link.
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 disconnect your keypad strip as shown in the photo below, then remove the screws that hold your circuit board in the old
frame.
Then carefully (since the display is made of glass) move your circuit board to the new frame, and reassembly is the reverse of
disassembly.
