Refrigerator Energy Efficiency

Check the gasket (soft plastic piece that seals the door to the body of the refrigerator) for gaps and improper fit. The door should close firmly against the gasket. Check the tightness of the door by placing a dollar bill between the gasket and the door. You should feel a slight drag when you pull it out. Thinkstock

• Refrigerators cost about $5 to $8 or more per month to operate consuming 3 to 5 percent of your total energy use. Keep the refrigerator at 36 to 38 degrees F and the freezer at 0 degrees F.

• Do not locate an oven or heating appliance close to a refrigerator, as the refrigerator will have to work harder to keep items cool. Do not put refrigerators in unconditioned rooms such as garages or porches. Turn off, clean, and unplug seldom used refrigerators.

• Try to keep the door open no longer than necessary.

• Vacuum coils and keep drain trays clean.

• When buying a new refrigerator, use the EnergyGuide label to compare the efficiency and cost of operation with similar models and capacities. Look also, for the ENERGY STAR® label.
