With the extreme cold we have been getting I am understanding why a garage fridge has a hard time in the winter. I have heat in the garage but I have only been turning it on when I work out there. It is a two car, attached and insulated. My thermostat does not show any temp below 40degrees so I don't know the exact temp when I am not heating. Anyways.... I read someplace else about a "garage kit" for a refrigerator. I have a sub zero fridge and a Kegerator in the garage. I noticed today a pop out of the fridge was slushy. I cant find a garage kit for sub zero. Anyone with knowledge of appliances know if these could be universal to a degree, or if there is a manufacturer out there that makes something for sub zero? I will try to contact them tomorrow.
