Refrigerators and freezers
- Don't keep your refrigerator or freezer too cold. Recommended temperature is 37 to 40 degrees Fahrenheit for the fresh-food compartment of the refrigerator and 5 degrees Fahrenheit for the freezer section. If you have a separate freezer for long-term storage, keep it at 0 degrees Fahrenheit.
- Defrost refrigerators and freezers regularly. Frost buildup decreases the energy efficiency of the unit. If you have a manual-defrost refrigerator or freezer, 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 or the seal may need replacing.
- Cover liquids and wrap foods stored in the refrigerator. Uncovered foods release moisture and make the compressor work harder.
- Clean the condenser coils. Move your refrigerator out from the wall and vacuum its condenser coils once a year unless you have a no-clean condenser model. Your refrigerator will run for shorter periods with clean coils.
