I have watched the video how to change the bulb(WPW10440740) on a microwave/oven combo and mine looks a lot like it. I removed the upper and lower vent grills and removed the two screws at the bottom holding it in. I even removed a lot of unnecessary screws, but it is not budging. Does anyone have any clues? I feel like there must me screws at the back or sides holding it in. Taking the entire oven out is going to be a huge task that I am trying not to do unless absolutely necessary.
