Our Norcold NXA 841 has stopped working in the main part of the refer unit. it will only get cold in the freezer and will not get cold past 48 degrees F in the main section. The freezer get cold to - 23 degrees F, all the other functions, control panel seam the function properly. I checked the door seal and it seals good, also made sure that when we loaded the refer that nothing was in the way of the door sealing and the food that we loaded was cold from our home refer to the RV refer !
