Hi Rose Ann! Our new refrigerators are designed to be more efficient in that they use newer components and run at a consistent speed/temperature for a longer period of time using less energy. If your refrigerator is located in a non-humid and not warm environment and you have set your appliance to the appropriate temperature settings (37ºF for refrigerator and 0ºF for your freezer section) you should notice that it runs at a lower speed for a longer period of time. This is one way it is designed to save on energy. Appliances use more energy when they constantly turn off and on. Our refrigerators are designed to allow the fan components inside to run after the compressor turns on. This allows the internal components to cool and the machine to rest even though you may still hear something running. I hope this information soothes any concern you may have about how much the refrigerator runs.
