If there's no obvious removable cover over the bulb (and the owner's manual doesn't address it) some disassembly may be required.

Always unplug a microwave before removing or installing any bulbs.

The outer cover (wrapper) will need to be removed.

The screws you need to remove should be pretty obvious, and a special driver (such as a T20H Torx type or GTXH20-100) may be needed.

Be sure to put all the screws back in the right holes, since some may be special grounding screws.

Bulbs can be had in most grocery stores, hardware stores, home improvement centers, and big box or department stores.

Many models use halogen lamps. You must not touch the new one with your bare skin, as the oils will shorten the bulb life.

Here's the scoop, for this model specifically:

1) Take the top of the case off. There's some Phillips screws, and two vandalproof ones: torx with a post in the middle. So you can have the right bit ( ). Or, plan B: often our helpful Taiwanese friends didn't make the post quite long enough, and so apply enough pressure and you can remove it with normal torx (a.k.a. star) bit. Plan C: get a drill, a smallish drill bit, and blast that post out; then the torx will unscrew it, or if you don't have a torx even a small flat head (slot) screwdriver of the right size.

2) Look at the side with all the interesting stuff, behind the LED screen. See the off-white plastic thing telling you about "Max 40 Watts, Min 40 Watts"? On top of that is the black base of the light bulb, held down with two long thin white plastic clips.

3) Press the clips in, take the bulb out. Unhook the power leads too, of course.

4) Put in the new bulb. There's the kicker: where did you get your new bulb? I don't know. It's a T170 bulb, and the black base and the bulb is all one piece so stop trying to yank or screw it apart. You may have found one here:

or here:

5) Stick it in. Undo steps 1, 2, 3.

GE Spacemaker Micro/Oven Need to change (inside) light bulb on model #JVM1490SH02 Serial # TH901044K. Where is the bulb located?

While replacing the cooktop light can be done by accessing the cover on the bottom of the oven, replacing the cavity light will require you to pull the oven from the wall and remove the outer cover.

The installation instructions are very handy in this case, 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.

Also, most bulbs can be matched up at hardware stores, home improvement centers, and places like Wal-Mart or even large grocery stores.

These use halogen lamps. You must not touch the new one with your bare skin, as the oils will shorten the bulb life.

Help on a micerowave!!

F3 on a GE / Hotpoint microwave means you have a shorted keypad.

Unfortunately, that part is not cataloged for this model.

In fact, the parts catalog says it you have problems with this model, you must return it to the place of purchase!

Not very helpful, but please don't kill the messenger! *grin*

You might try contacting GE to see if they will help.

Here is info from another person having that problem on fixya.

I had to go down to an appliance parts shop in PHX to get the lamp after I had taken the microwave out of the corner cabinet and disassembled it. Found the light bulb toward the right front top corner after taking the frame all apart. It was a pain but it's done !! BTW, I'm a female licensed electrician and GE told me over the phone that I would have to call a service tech to come replace the lamp (about $200). I searched the websites for the part number to get the lamp (it wasn't printed on the lampbase), searched for local appliance part stores and found the part number (WB36X10131) to pick it up. The "cavity" lamp cost me $8.65 then the cost of the gas (about 40 miles) to get it but my micro was back up and running before Thanksgiving dinner --just in time to make Lean Cuisine !!! HAHA Thanks for your reply Guru !! Have a great weekend !! Julie

Is the Advantium Mod: SCA1000HCC03 the same as the SCA1001SS?

They are indeed the same bulb, a 10W halogen. Care must be taken not to touch the lamp, as the oils from the skin will shorten its life. In many recent models, the oven must be removed from the wall (a two-person job due to safety concerns) and the cover must be removed. The manufacturers consider this a "technician-only" type job to lessen their liability. You can find helpful exploded view diagrams of both ovens and order the bulbs here:
