Recharging older Adler Barbour Cold Machine

[Mexico Mike]

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...

Thanks,

Mike

Prior to changes to the clean air act of 1995 Adler Barbour did not provide a refrigerant servicing port on their units, they did sell a dual line connector with a gauge to add refrigerant with. If unit has held refrigerant all this time the leak is probably a micro corrosion hole in evaporator and is not repairable. I would check with local boaters to see if someone has an AB servicing quick connect servicing gauge.

Thanks for the responses. If I was anywhere but here I'd probably bite the bullet and get a new unit, but it looks like we'll try to get this one working here.
