If it is installed like mine is in the wall cabinetry with stainless (or other)molding around it to frame it in, you will have to remove the molding - just unscrew them and then remove the microwave - looks like any regular countertop microwave and put it on a surface where you can then remove the top off of it - again more screws. It's really not that difficult, just time! I know it sucks and I have had to psych myself up each time I've had to work on it (I've replaced the magnetron twice - and a fuse). Truth be told, I wish I would have replaced the bulb the last time I got it out too! If you have a teen handy, have them help you fetch it from the wall to surface. Good luck!
