Ice Makers will increase operating cost by 15% to 20%.
Through-the-door ice and water dispensers will add another 10% to 15% to operating costs. Each cubic foot larger adds about 25 kWh per year.

Use these wise tips:

  • Locate away from heat sources such as the oven or a heat register. Avoid direct sunlight.
  • Don't place in unheated garage. Poor temperature and humidity control can spoil food.
  • Allow at least two inches of clearance around the refrigerator for air circulation and heat dispersal.
  • Keep temperature of fresh food section between 35 and 40 degrees; freezer at 0 to 5 degrees.
  • If you have an anti-sweat switch, use it only when condensation forms near door seals. The switch heats the area around the door seal to prevent condensation. Turn off in the fall to save energy.

Buying tips:

  • One larger refrigerator uses less energy than two smaller units.
  • Look for ENERGY STAR® label.
  • Use yellow EnergyGuide labels to compare.
    • Side-by-sides generally use more electricity.
    • Through-the-door dispensers and automatic ice makers increase electric use.
