Been chasing an extremely intermittent issue and we seem to have it isolated to our PM3000. The problem goes away if we turn off the PM3000 and turn it back on. I won't take my time or yours to detail the issue here. Only does it every few months so very difficult to accurately diagnose. As a result, I'm looking for a reasonably priced, fully-functional unit to install. Anyone have one that was replaced as part of an upgrade?
