Lol 4 pages later, and the little engine that could finally conquered that true self contained unit. He smiled proudly as he wheeled it back into the store, only to find Coke had already Ben out and replaced it with a new unit. The customer asked the little engine if he could kindly scrap that junk and went about his day.

Saddle valves man. Always just put some saddles on there and find out what's going on right off the bat. Chasing your tail playing the guessing game for days rarely ever ends up being worth the headache of not just playing out the diagnoses from A to Z.. Especially on little cap tube systems with 134a. That gas and its oil plugging issues is a wash. At this point. First thing I do with any 134a system is pull it, evac to 300microns and drop in MP39 (401a). Then go from there. 50% of the time just changing the gas does the trick. 134a is god awful gas. And I don't care what anyone says to defend it with its low CFCs and all that nonsense. It plugs driers and cap tubes. way too often.
