Hello , can one of you help me ? In my camper I have an Electrolux refrigerator which automatically operates from shore current , gas and 12 volts . I close the refrigerator always 2 days before we start off at shore current . At the latest after one and a half days the refrigerator should be cold which but not true but it is only slightly cooled but not cold as it belongs to a refrigerator , nevertheless that it is fully turned up . When we start off sprin g the refrigerator to gas around . Once we arrived at the destination the refrigerator is cold , just as it belongs . I connect the RV back to shore current at u the refrigerator is again only so slightly cooled the next day but no cold …………. He shows no interference at nothing …….. Why does it cool over gas better than over electricity .
