Oooh this is great and timely info. I installed one of these at the mother in law's a few years ago, works great but lately the compressor has been shutting off. Threw some low suction error or something (don't really the number literally just deleted it earlier today), shutting the whole thing down for a bit seems to reset everything, but it keeps recurring. I'm not local but should be able to repair over Christmas if this is in fact the issue.Digging this back up since I have a bit of a functional update. Actually, more of a piece of advice for anyone who has bought a Rheem Proterra.
Go ahead and spend the $20 and order a new set of 4 thermistors.
