I have a G E Spacemaker Microwave which I am trying to remove from it's under-the-cabinent position. I have removed the 4 screws which attach the unit to the bottom of the cabinent. The only thing holding the unit in place is the rear mounting plate. According to my installation manual, I should be able to tilt the front of the unit down and slide it out. I have tried this as well as tilting the front up and pulling. I have also tried pulling the unit straight out. Nothing seems to work. I would appreciate any advice from anyone on how to remove this unit. Thanks.
