Sub Zero Update
Well, everything is cleaned out and it's been running for a while now. Actually, the freezer works great (except for the light, which doesn't work) but refrigerator section doesn't work. The fan works, but it doesn't get cold. It sounds like the compressor is running, however, so maybe it just needs coolant?
The works of this thing were FILTHY. I think they had ran it while they were ripping up the kitchen at whereever it came from.
