I have a GE Spacemaker XL1800 over-the-range Microwave oven that I need to remove and replace with a newer model, different manufacturer. As I recall the oven slides into a back mounted hanger. My question is how do I get to the screws or bolts that release the oven from the hanger so I can pull it our vertically?

Thanks,
Russ

Perhaps reviewing the installation manual will help if you reverse the process:

The answer lead me to the instruction manual I was googling before I came to this site.
