Preventive freezer maintenance prolongs its life and reduces the times it has to be serviced. An easy preventive maintenance you can do is to clean the freezer condenser coils often for safety and energy efficiency.
A freezer along with the refrigerator is one of the few appliances in your home that runs continuously, day and night, keeping your food cold. If you consider how hard a freezer has to work, it is pretty amazing that they rarely breakdown.
Temperature settings for refrigerator and freezer compartments are often given arbitrary numbers by manufacturers (for example, 1 through 9, warmest to coldest), but generally 37 to 41 °F is ideal for the refrigerator compartment and 0 °F for the freezer. Some refrigerators must be within certain external temperature parameters to run properly. This can be an issue when placing units in an unfinished area, such as a garage
In the past, freezers and refrigerators consumed more energy than any other home appliance, but in the last 20 years progress has been made to design, manufacture, and encourage the sale of freezers with improved energy efficiency. Current US models that are Energy Star qualified use 50% less energy than the average models made in 1974. Energy Star is an international standard for energy efficient consumer products originated in the US. It was created in 1992 by the Environmental Protection Agency and the Department of Energy. The most energy-efficient unit made in the US consumes about half a kilowatt-hour per day. Larger units, especially those with large freezers and icemakers, may use as much as 4 kWh per day.
