Our Norcold Refrigerator in a 2016 313 RLTS kept shutting completely off. We had several visits from mobile RV techs and talked with Norcold tech reps. Had the voltage output checked from the battery/converter and there were no evident problems. The mobile tech said often fluctuating 12V power would cause the units to shut down. Finally we disconnected the converter and hooked up a good battery charger to the battery. The refrigerator worked fine for the next 3 days. I replaced the WFCO converter with a Progressive Dynamics Inteli-power 9200 series converter. Solved the problem!
