I have a 2000 Searay 540 Sundancer and my refrigerator is leaking freon but has not gone completely out. I recharged it but it only lasted for about a week. It will only keep things slightly cool and the freezer is slightly colder than the fridge. I cannot find a replacement fridge that is the same size as the GE model that is in there now. I have checked Norcold and did find one that is the right size but it only comes with AC/DC AND propane gas. I don't need the propane. Does anyone have any suggestions or have you been through this? Help The size is 59 H x 23.5 W x 34 D.
