Great response. I just ran through the diagnostics last night (to see if anything jumped out at me) and this morning it all seems to be accurate. Traditionally, I would hear the temp on a radio news report or temperature would be displayed by a bank (or some other business) and my OAT was usually within about a degree or so. During a recent "pod" replacement, I dropped the front swith plate (on a carpeted floor) and although I did not do any physical damage, I thought I might have jarred something out-of-spec because when I reinstalled it, it seemed to be high almost 10 degreeesF. Today it was right on.
