Refrigerator and Freezer Tips

  • Refrigerators and freezers operate most efficiently when full but not overcrowded.
  • Arrange contents in a way that allows air to circulate.
  • Keep the freezer full by filling plastic milk bottles with water.
  • Make sure refrigerator and freezer doors fit tightly. If they don't, adjust or replace gaskets. Here is a simple test: Shut the door on a dollar bill. If you can pull the dollar out easily, the gasket is not sealing properly. Try this at several locations around the door to check for uneven seal.
  • Don't open the doors unnecessarily.
  • If you're going away, remove perishable food from the refrigerator and turn the thermostat up a few degrees.
  • Don't put uncovered liquids in the refrigerator. They force the unit to work harder to remove the moisture.
  • Let cooked food cool to room temperature before putting it in the refrigerator.
  • Don't put foil on the refrigerator shelves. It blocks cold airflow and makes the unit work harder to cool food.
  • Don't locate the refrigerator or freezer near the stove, dishwasher or other heat-producing appliances.
  • Don't locate the refrigerator in direct sunlight.
  • Set your refrigerator thermostat at 40° and your freezer at 0°.
  • If your refrigerator has an "efficiency" setting, make sure it is on. This will reduce the number of hours the unit needs to run.
  • Defrost frozen foods in the refrigerator.
  • Clean dust from refrigerator coils.
  • Don't store paper bags or anything else behind the refrigerator. They can cut airflow to the coils, making the refrigerator work harder.
  • Don't try to cool the house with the refrigerator.
