Nick -
I'd start with the simple stuff. I looked up the wiring for the monitor panel to see if it was fused and it is. You can get an idea of the wiring by looking at the diagram in this owners manual. I know its not the same year as yours but it'll help.

The low voltage fuse panel for our 2201 is located under the couch base. The best way to check a fuse is with a test meter. A fuse that looks bad is bad of course, but a fuse that looks good, could still be bad, a test meter will always let you know for sure.
Concerning the fridge, since it's still working, we know it has power, I'd test the bulb. I don't know how much trouble it is to get to that bulb, our fridge doesn't have any sort of indicator light on it, I wish it did.
