For a freezer to maintain the desired temperature of 0 degrees F, the compressor will usually run more than 50% of the time. Modern chest freezers have smaller, more powerful, high-speed compressors that generally cost less to operate than those in older refrigerators. These compressors are designed to run 80 % to 90% of the time. This makes them more energy efficient because the greatest amount of energy is used when the compressor cycles on.
Factors that contribute to run time:
In extremely hot, humid areas, run time may approach 100%.
Loading the freezer with a large amount of food, especially warm or hot foods. Hot foods should be allowed to cool before being placed in the cabinet.
Another significant factor that contributes to run time is an empty or lightly loaded freezer. Because no insulation material is perfect, air alone does not retain cold. A freezer must run more to maintain temperatures low enough to satisfy the temperature control and turn the compressor off. A freezer should be at least 3/4 full to maintain proper temperatures and reduce time.
Door openings contribute significantly to the run time of any refrigerator. When the door is opened, some of the heavy cold air slides out of the cabinet, pulling warm air in at the top.
