I have a Norcold 8801 as well. Unit level, evap fans working, condenser fans cycle on and off as heat rises in condenser area. Nothing blocking condenser vent shaft. Granted I have a side vent unit. But you would think if Norcold knew there was an issue, they would have a recall. Thermister in proper place, doors seal good as well as center flap. Still can't get it below 40, freezer is fine. Dealer says when they "checked it. It was at temp. Although they didn't say what the temp was or what all they checked. Not sure what else to check. Ready to contact RV manufacture or Norcold.
