Ok, maybe not highly technical, but I couldn't figure out where else to put it. And in my case the refrigeration cycle has always been mystifying enough to qualify as highly technical. So, we have two freezers in our garage: the top section of a normal over/under reefer, and another horizontal unit my Dad gave us. On certain days during the winter the garage temperature will fall below 25-30 degrees or so, and the food in the freezers will actually soften. I'm not sure what's going on. Any thoughts?
