Not sure on your model but my Kenmore Microwave has the bulb up above the plastic ceiling inside.
It's semi-rigid so you flex it slightly and the tangs come free and it comes down.

microwave's have fuses in them. try and replaceing them before you call the repair man.check on the web. for locations of fuses,hope this helps

This is simple, and "FixYa" technical staff has clearly not looked at our model.

Take off the vent across the top (three long screws) to expose a single screw over the keypad.

Remove the single screw, and the whole keypad consile will lift up and off, likely hanging by a plastic tab/support on the bottom.

Now you can twist the light bulb plug to remove it from the support structure, change the bulb, and replace all that you've done.

Simple.

That would be a defective secondary (lower) door switch or possibly the door switch mount is loose or misaligned.

We have the service manual for this model and have uploaded it to our site here to help you.

Your post has two distinct model numbers shown, so it's hard to be precise, but I'll try my best.

I have a diagram at my site which helps you find & replace many GE cooktop and cavity light bulbs. Other models are similar. It's at

Always unplug a microwave before removing or installing any bulbs!

If it's an over the range type, remove the vent grille across the top and see if bulbs can be accessed there.

There may be a panel on the bottom covering the light(s), too.

If not, chances are you'll have to remove it from the wall, then remove the outer cover.

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

If yours is an Advantium type, the following instructable should help: http://www.instructables.com/id/SZFF4WSF44XYT8X/?comments=all

I fixed it by reading how to fix another model. What you do is take the cover off, the bulb is on top. Make sure that you unplug it before starting.

The manual is on the Emerson site at:
http://www.emersonradio.com/owners/MWO%20manual/MW8115SS.PDF

But it doesn't seem to mention a way for you to change the lamp.

Manufacturers used to include access panels in the rear or side so you could easily change the bulb. That exposed the customer to 110V connectors, and that posed a real liability threat, so they stopped using them.

You now must generally remove the outer cover to replace the bulb.

If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk
