Check refrig temp
I had the same rig and you can put the setting on automatic for gas or electric and it will run fine. However, Please keep an eye on the food compartment temperature.. during a trip out West with the refrigerator running on gas while driving, the internal temp went up to 50 twice, and we had to throw away the contents. I discovered the issue was the coach temperature. While we were cool sitting up front with the chassis air on, the rear was 80-90 degrees, and the refrigerator could not compensate. My solution was to run the generator with the house air on. And yes I had it to 3 different RV shops and they could not find anything wrong.
After that trip I replaced the Norcold with a residential unit and couldn’t be happier, my ice cream was finally frozen.
