Begin by unplugging the unit. As a safety precaution, wait several moments to unscrew the cover plate. Once you have removed the plate, take out the dead bulb by unscrewing it one quarter turn to the left and pulling the base straight out. Examine the bulb to ensure you have the correct replacement. Like automotive bulbs, those found in microwaves have two prongs and are readily available at a local hardware store. Push in the new bulb, and rotate it one quarter turn to the right. Screw the cover plate back on. Plug in your microwave, and open the door. The lighting should now be functional.
