Norcold has discontinued the 636388 upgraded board, so it's no longer available. If it's getting too cold, try moving the thermistor clip higher on the cooling fins first, which makes it run warmer. If you end up needing a new optical board, the upgrade path for the N611V is the Norcold N7X, which has the same cutout.
