I just finished a hunt for a new to me boat, of the 9 boats I viewed 8 of the boats the Fridge/Freezer was inoperable. The boat I bought the surveyor said it just needed Freon added. As this is such a common problem with boats. I believe my boat has SeaFrost? refrigeration unit and will find out shortly if it has fittings to recharge the system. Either way I am going change the compressor out for a Cool Blue Unit, as these will last for 12 to 15 years.
