How to make your refrigerator use minimum energy when filled with food?

• Not once the food gets cold. The cooling wection should be kept full, with enough room for some cool air to circulate for even cooling, and the freezer compartment should be tightly packed, so that the frozen foods can keep one another cold.
• If there is not enough food to fill the freezer, it is suggested to put more ice trays or some containers of water.
• Frozen food in a fully packed freezer will survive a power failure for quite a while if the door is kept shut.
• Some extra water containers in the cooling section will also minimize the amount of in rushing warm air that has to be cooled when the door is opened and shut.
• There are other ways to keep your refrigerator's condenser from working over time.
• It is permissible to let hot food cool some what before refrigerating it as long as cooling period is not long enough to permit bacterial growth. Never use warm or hot water to make ice cubes.
• Cover moist food, so that the refrigerator does not waste energy evaporating the moisture.
• Check for the recommended temperatures, 37 to 40 degrees fahrenheit in the cooling section and under 5 degree fahrenheit in the freezer compartment.
• Clean the condenser coils behind the refrigerator the way the manual says, and make sure there is enough room behind and above them for the warm air to escape.
• Make sure the door seals are tight; Test them to see if they hold on to a dollar bill when you tug it.
  
• The most important, keep door opening to a minimum, repace several items at a time rather than making seperate trips.
