After 5 years of good performance`(since`I've owned the boat-unit is older than that) the little "freezer compartment" only freezes on the side the refrigerant enters. Seemed like it might need a top-up with R-12, and here in Fiji
they still have some and will use it. Only problem is, the Fijian refrigeration
tech who came to my boat couldn't see anywhere to hook up to the unit, and I couldn't either. Can anybody help on this? Could it be possible is nowhere to put in more refrigerant? He wants to remove the unit and take it to his shop to retrofit some fittings and I'd like to avoid that...
