I'm thinking of replacing our ancient but functional LEC 12 V fridge with a mains powered one (various reasons, but not in a rush to do it). Now, most mains fridges have a climate rating of 10 C or 16 C to something fairly high. What happens when the temperature in the boat drops substantially below the lower temperature range? At some point presumably the fridge gives up and ambient temperatures are cold anyway, but does anything undesirable happen? The boat is unoccupied for at least several days a week, but I'd like to leave the fridge on so that we have ice for a G&T when we get back.
