19xr
Had a problem with losing power to the machine. Found out the battery back up was bad and Carrier had to reprogram the board. After it was reinstalled, I had trouble with the display coming on. Removed COMM and power line and it came back on. Also one of the oil psi transducers is reading -4.7, Carrier recommends changing
it out if it will not zero out for calibration. Anyway if this was a Pic 1 series, 1998 machine, should it of been ungraded to a Pic 2?
