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
