We have a stock refrigerator system for our Hunter 320. When we bought it from the dealer it had not been used for several months and the system did not cool. They recharged it and it has worked continuously until recently.We just had the boat worked on for 6 week - uhg - and the refrigerator does not cool. Two Questions-Has anyone else ever experienced this?I have the instructions for the Refrigerator but there is nothing about recharging the system. Is this something I can do?Steve Dale
