Defrost your refrigerator regularly so it can operate more efficiently.
Vacuum and clean the condenser coils, motor and evaporator pan of your refrigerator once or twice a year, and leave space between your refrigerator and the surrounding walls and cabinets to allow air to circulate around the coils.
Keep your refrigerator away from the stove and heat registers. By being next to those items, you’re making your refrigerator work twice as hard and decreasing its overall efficiency.
Test your refrigerator and freezer by placing a thermometer inside for an hour. The reading should be as follows:
Refrigerator 36-38°F 2.2- 3.3°C
Freezers 10-15°F -12.2 – -9.4°C
Select a refrigerator/freezer with energy-saving features. It will use 20% less electricity than the standard model.
Avoid purchasing used refrigerators, as an older refrigerator often uses more than three times the energy of today’s models.
Make sure the seals on your refrigerator, freezer and oven doors fit tightly.
