Thanks for the input. I think I found the AC outlet. It is behind the tall cabinet-type drawer beside the frig. The frig may never have been plugged in. I think that because the PO had bent the outside cover so that the frig AC cord would plug into the outside outlet with the cover closed.
On to the cooling problem: the red light is not blinking. I would guess that the problem is the controller board, but I hate to replace it on a guess.
