I have had refrigerators in the garage in several homes, some better insulated than others. I feel I am a reasonably informed consumer, and I research and read about products in depth before I buy. That being said, this is the first time I have heard about the temperature limitations for refrigerators. Perhaps mine were old enough that didn't apply or maybe I just got lucky, but I've never had this problem with either a fridge or a freezer. I would never have posed the question, thus I would have been in the same situation as the consumer. Live and learn.
