Step 4: Bulb Replacement
Although the picture is poor, if you look inside the unit you will see a small shiny reflector that hides the bulb. If you place a flashlight in the microwave pointing up, it will be easier to locate the bulb. The reflector is simply a "pinch fit" into the unit. Sqweeze it a bit, making sure not to bend it and it will come right out where you can work with it.
