Here are Refrigerator/Freezer Energy Tips:

• Look for a refrigerator with automatic moisture control. Models with this feature have been engineered to prevent moisture accumulation on the cabinet exterior without the addition of a heater. This is not the same thing as an “anti-sweat” heater. Models with an anti-sweat heater will consume 5% to 10% more energy than models without this feature.
• Don’t keep your refrigerator or freezer too cold. Recommended temperatures are 37° to 40°F for the fresh food compartment of the refrigerator and 5°F for the freezer section. If you have a separate freezer for long-term storage, it should be kept at 0°F.
• To check refrigerator temperature, place an appliance thermometer in a glass of water in the center of the refrigerator. Read it after 24 hours.
• To check the freezer temperature, place a thermometer between frozen packages. Read it after 24 hours.
• Regularly defrost manual-defrost refrigerators and freezers; frost build-up decreases the energy efficiency of the unit. Don’t allow frost to build up more than one quarter of an inch.
• Make sure your refrigerator door seals are airtight. Test them by closing the door over a piece of paper or a dollar bill so it is half in and half out of the refrigerator.
• If you can pull the paper or bill out easily, the latch may need adjustment, the seal may need replacing, or you might consider buying a new unit.
• Cover liquids and wrap foods stored in the refrigerator. Uncovered foods release moisture and make the compressor work harder.
