rv refrig problem
Hope you got what you need from rvmobile. I use it on occasion as well, but thought that I'd offer an opinion as well. I'm sure by now that you have confirmed that the coolant is leaking as it is ammonia and you at least need a new cooling unit. But since it is an 85 refrigerator and the cooling unit probably will cost you more than half of the price of a new refrigerator, I would go with a new one since the cooling unit would have a guarantee, but no other part will if you only replace it.
Hope that all is going well!
