      I’m hoping to tap into the membership’s vast knowledge. I own a 2 year old Northstar TC650. It was optioned with the compressor fridge based on all the good reviews and pluses over the absorption models, many from this website. It seems to have worked well until now.

      I started it up and after a few hours checked the temp in the freezer and fridge. The compressor was constantly running and the fridge never got below 50 degrees. The freezer got to -13 degrees. Thinking it might need more time to cool, I left it on for 24 hours with the same results. Clearly the cooling system is pumping but the coldness isnt making it to the fridge. I’m guessing the thermostat is somewhere in the fridge and it never gets cold enough to tell the compressor to stop. I turned everything off and let the fridge sit for a couple days and then fired it up again with the same results.

      I have done an internet search and very few problems with these fridges have been documented and none describe what I am experiencing. I’m hoping someone can shed some light on this. Thank you in advance.

      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.

      It sounds to me like there is an airflow blockage between the freezer section and the fridge section. I believe that all of the cooling comes from the freezer section and the refrigerator section cools by convection from the freezer unit. Sounds like it’s not frost blocking the airflow since you turned it off for days to defrost it. Maybe the Dometic has some sort of circulating fan to move air around the box that has failed? Good luck and let us know what you find.

      Hello John, here’s a couple of thoughts is the latch at the top of the refrigerator door still in the vent position. If so this would allow air in the main compartment but yet the freezer would still work. Another thing to look at which will require you to remove the refrigerator, is to check how dirty the condensate coil is and if the condensate fan is working. The new model CRX has a condensate coil very much like your house hold refrigerator and requires cleaning from time to time just like at home.

      Let us all know your solution to your situation with the CRX.

      We just published an outstanding article by James Young that addresses most issues with this refrigerator.
