I've had my microwave for a little over two years and after 6 months, buttons 2, 5 and 7 stopped working. The "low" feature of the vent never worked. I was told I need to replace the control panel asm - is this different to the control panel membrane? GE could replace the part for $250 but the appliance only cost $299. I hope to replace this myself.
The control panel module is different from the membrane. Unfortunately these modules themselves are usually very expensive, perhaps 1/2 the cost of a new microwave.
Sorry.

Remove the grill, should be screws on the top of the unit. There should be one screw behind the grill at the top of the control panel. Remove it and pop the control panel up to remove it. Make sure the mw is unplugged first. Then you can remove the board.

Generally, the most common causes of a failure to heat are:
- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part

We see (and repair) this a lot. The problem is on the control panel, which
we regularly repair nationwide by mail for $39.95 postpaid.
This light failure often occurs when a bulb goes out and the filament
shorts, or when the bulbs are removed or installed without first
unplugging the oven from the power line. Either can cause such a
failure on the controller.
This can often also affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on too.
Details of our service and critical safety information and disassembly information is at our site, and our link is at our listing here on FixYa.

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.

There
should also be a "mini-manual" hidden inside the unit behind the
control panel or hidden on the left side behind the grille, which is
very helpful when troubleshooting & testing.
If you would like to have us do this for you, we do that for $39.95 plus part costs.
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.

Your vent flap could be taped or it could be faulty installation not allowing the vent to open. If you take the front vent cover off, you should be able to reach in above the fan unit and gently push the vent flap up, it should move freely with no binding. If it doesn't it is taped or blocked. If it is taped, gently putting upward pressure on the flap might release the tape. If that doesn't work the vent installation is blocking the flap. You might have to remove the unit from the wall (two people to do this) or disassemble the vent duct above the microwave and rework the interface for clearance.
hope this helps,
