Yes, anytime you think to yourself "I wonder how to get behind this" in the 330, it's only a half dozen screws and it's out. That goes for the fridge, microwave, any of the drawer compartments, the liner panels in the aft cabin, etc. I've had just about everything out 6 times in the last few months and no issues putting it back together.
Put some moving blankets down on the floor and prepare to vaccum up the rust that will flake off the bottom of the fridge. If it is the original one it is lighter than you might expect and you should be able to set it down on the floor.
I mounted a power strip with USB outlets and plugged in in place of the fridge.
