Thanks. Yes we've owned since new, and no its not part of the recall work which we had done. It could be option (fleetwood) not utilized? as I just cant find where blue wire might have been connected. I'm pretty sure not actually part of refer due to lack of any Dometic documentation anywhere. I find it odd would have been just stuffed in loom open ended if its hot-more puzzled at the soldered on power wire though because it looks like something I might have done, possibly was a separate plug that wouldn't fit on new board when changed out. Cant imagine doing that without looking at what was being powered.
Tomorrow Ill reconnect the red wire to power from 12v heater feed, test blue wire to see if its energized when 12v heater turned on, though that wouldn't explain purpose of the lil potted box and or where blue wire goes or went.
