Well, nearly everything in the freezer thawed (sorry for the dramatics ... no fires or anything), except for stuff at the evaporator area at the bottom. The refrigerator also became essentially room temp. The fan that was working periodically is the condensor fan. I didn't know until recently that the "coolness" is distributed from the evaporator to the upper freezer and the fridge also via another fan ... controlled by the defrost thermostat apparently. I spoke with an Amana repairman and he states that it is common for my particular fridge, since the water reservoir is at the bottom of the refrigerator, to freeze the reservoir if the defrost thermostat or, less commonly, evaporator heating coil, has gone bad ... just because of it's proximity to the frozen evaporator. Anyways, after having it defrosted and plugging it back in, the water dispenser works ... so I must assume that it was frozen somewhere between the intake and my glass of water. The new defrost thermostat also brought the fridge back to life.
So, my contribution to this thread, aside from taking much away from it, and having a fixed refrigerator, is that if the water dispenser stops working at the same time as the defrost system fails, it's likely because the water line is frozen somewhere along it's path near the frozen evaporator. At least on my fridge the defrost thermostat not only controls the heating coil on the evaporator, but the evaporator fan itself. I'm not sure if every system is like this, though.
Thanks again everyone!
