1: Unit cools much better on gas operation.
2: Check often to verify thermostat setting. When the outside temperatures are below 30 degrees and 90 degrees, the refrigerator has a harder time cooling, especially when the door is opened constantly.
3: Make sure the outside vent is clear of debris, branches, etc. If possible, open the outside access door to get more air flow to cool the refrigerator coils.
4:If the refrigerator is not cooling sufficiently:
A: Ensure that the coach is level.
B: Open the outside refrigerator vent door to dissipate heat for the coils.
C: Turn up the thermostat during the day and down at night (if needed). Setting #4 is your average temp setting. Some models are fully automatic with manual overrides. When the automatic functions sail, it is necessary to completely shut off the refrigerator. You can us cold ice packs, dry ice, or ice cubes in vegetable bins to cool it manually.
5:After the refrigerator is turned off, dry the inside with a towel and put crumpled newspaper in both the refrigerator and freezer to keep it from molding or smelling.
6: Do not open the refrigerator or freezer doors while traveling. It takes longer to recover when traveling then it does when parked (up to an hour).
7: Both the refrigerator and freezer compartments need air circulation inside to cool properly. Therefore, do not pack them too full of food and do not cover the grates inside with plastic or foil (except the bottom one) because this will reduce the circulation of air.
8: Turn on the refrigerator hours before you plan to load it so it will be fully cooled. Also, it is a good idea to pre-chill the food you plan on taking with you.
9: VERY IMPORTANT: A refrigerator must be close to level to operate properly. Operating in an unlevel state can cause permanent damage to the unit. It is ok to operate while traveling in unlevel conditions as the movement of traveling keeps the refrigerant moving.
10: Sometimes the doors are hard to open right after closing. This is a good thing, as it means there is a good deal on the door gaskets.
