We found the best thing to do is start it on propane and do not open the freezer or refrigerator door for six hours. Then load your freezer and refrigerator with pre frozen or chilled items and press the auto button on the eyebrow control panel of the refrigerator. We were loading it before it cooled down and it would never get cool, just the freezer part would freeze. Then we had a big storm move through the area and power was out for 5 or 6 hours in the entire state park. Low and behold our refrigerator worked like it was suppose to! Lesson learned.
