Removal of Sharp OTR Microwave/Convection Oven

Make sure there are not screws/bolts from just inside the cabinet on each side going down into the microwave. Shelf paper or something covering them? Feel for them with your fingers, if you have to. Maybe filled in with paint or dirt? I am not familiar with your rig but microwave mounting is not much different than a home. They should be there. Once the bolts are removed and the front of the unit lowered some, the back of the microwave should lift off a lip in the back.
