It's repaired. I got the final update. The compressor was replaced because it was disfunctional and leaking. This is why it kills me when someone asks "why did you do that?" Always assuming that they're the only ones that know how things work. Not to get on a rant here but it reminds me of a typical visit to the local Home Depot.
Guy in red vest: "Can I help you find something?" Me: "Yes. Can you tell me where to find the mouse bait?" Guy: "Why do you want mouse bait, what are you going to do with it?" Me: "I'm going to capture as many mice as possible, put little red vests with nametags on them and let them loose in Home Depot."
Anyway, a certified service center put tracer dye in the system to locate the leak. When it was recharged after the compressor was replaced, they evacuated the system which, (I'm told) you only have to do to remove moisture in the system - then they recharged it, adding coolant with oil. The extra oil and the dye was too much for the system and the filter/dryer became saturated with oil and clogged. (so much for certified technitions being flawless). This caused the overpressure and the compressor would not keep running. The dryer/filter was replaced, system was recharged and everything works correctly now.
