Have you tried moving the “snowflake decal buttons” on the interior thermostat to a different position? On our new N* Laredo SC with the same CRX1110 fridge, we misunderstood at first which way to go to make it colder. Dyslexia of the CRX.
In the beginning, on our Eastern U.S. Color tour last fall, we had a constant interior humidity problem with the fridge. After discovering the “snowflake” mistaken identity, all has been well.
I hope yours is something this simple.
We just got back from a 15 day romp through Yellowstone and the Black Hills where the daytime temps varied from 103F heat in Nevada to a 21F Blizzard on top of Shadow Mountain across from The Grand Tetons, all within 30 hours. The fridge worked fine in all conditions.
