My old 1983 Adler Barbour seams to have a leak, how to repair?

Problems: Loss of cooling capacity. I measure 8 degrees F differential across the condenser. Cools but not to the extent previous.

Has been slow decline over years. Attempts to correct problem: Cannot find port to add R12. Is it feasible to disconnect the quick connects, take the compressor / condenser unit to a refrigeration shop, get it recharged, and expect the quick connects to work a second time?

Do such shops have adaptors to fill these units? ANSWER: Before we blame the Refrigerant for the problem, are you sure that the condenser is not clogged with dirt and the air flow is good through the condenser. I run into this problem all the time with these old units its usually their aluminum evaporator corroding through and very small holes are opening up.

These leaks can start up so small that it can take months for the refrigerant to leak out and the leak rate will get worse over time. I don't recommend you take the unit out for service. What I recommend is not a proper fix but it ... more.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
