The Norcold 2118 RV fridge was one of several things I discovered was broke this year after De-winterizing. The error code was AC re.
We looked it up. "AC relay stuck closed".
This means the fridge was on all the time in AC mode even when turned off.
I replaced the control board. So far so good.
FYI last year I added a digital temperature controller to the exterior factory fan circuit after I discovered the fan control thermostat wasn't working. I also added an internal fan parallel to the fan blowing on the fins in the fridge compartment.
All this helps to lower the internal temperature.
I'm thinking about added a couple more fans to the exterior and another to the freezer compartment.
