Dennis, if that is so, why does no leak show up on the leak down test? The refrigerant has dye in it, but none shows up at any seals. mcneely

I figured I had nothing to lose by playing with it so tried one of the cheapo R134a conversion kits from an auto parts store. That worked to cool things down. I suspect a leak somewhere since I must recharge annually, but that is very little trouble for the real benefit it provides.
