Bulb Replacement

Remove shroud . Two black philips head screws on side, and several on the back side. The two bottom screws on the back are special screws that a philips,straight slot, or hex screwdriver will not remove. I took a dremel tool with a thin metal grinding disc and created a straight slot through the centr of the two bottom screws. This allowed their removal with a straight slot screwdriver. Slide the cover straight back and off. The bulb is located on the top of the microwave connected with one screw. Replaced the bulb. It has two prongs that fit into the holder. Replace screw. Slide cover back on. It slides into retaining splines on 3 sides. Replace screws, and you're in business.
