Refrigerators/Freezers
- Don't block air circulation around the unit.
- Vacuum the condenser coils at least once a year. Dust-covered coils impair the efficiency of compressor operation and increase energy use. The coils generally are accessible on the back or bottom of the unit.
- Keep liquids in a refrigerator tightly covered. Evaporation may cause the refrigerator to work harder.
- Do not let frost build up more than one-fourth of an inch in a manual defrost freezer. Frost acts as an insulator, making the unit work harder.
- Replace door gaskets that don't seal tightly. An easy way to test gaskets is to place a dollar bill against the frame and close the door on it. If the bill can be pulled out with a very gentle tug or, worse yet, drops out on its own, the door requires adjustment or the gasket needs to be replaced.
- Be sure the refrigerator is standing level so that the door seals properly. Use a level or a glass of water set on top to detect imbalance.
- Keep your refrigerator compartment between 36-38 degrees
Fahrenheit and the freezer compartment between 0-5 degrees
Fahrenheit. Keeping temperatures 10 degrees Fahrenheit lower than these can increase energy use by as much as 25 percent (about $48 per year).
- If possible, locate refrigerators and freezers away from direct sunlight and other warm air sources such as ranges and heating equipment. Don't put refrigerators and freezers in a garage. They're manufactured to operate in ambient temperatures (the same all year round), not temperature extremes.
