Normal Refrigerator Run Time

There are many factors which affect a refrigerator's run time.
  1. Modern refrigerators with more storage space and a larger freezer require more operating time. They start and stop frequently to maintain even temperatures.
  2. When a large amount of food is placed in the refrigerator, it will transfer its warmth to the refrigerator, which will cause the motor to run more often as the refrigerator cools down the food.
  3. When the weather is hot, the refrigerator will run more often because it is working to remove moisture from the air inside the refrigerator.
  4. If the doors are opened frequently (or left open), cold air will escape from the refrigerator and the motor will run more as the refrigerator tries to replace the cold air. This is especially true when the weather is warm and/or humid.
  5. The temperature control dial also controls how often the compressor will run. The higher the temperature control dial is set, the colder the refrigerator will become, and the more often the compressor will have to run.
The normal temperature control settings are:
  • 5 for single-control refrigerators.
  • 5 and C for dual control refrigerators.
  • 9 is the coldest and 1 is the warmest. In most models, the letter (freezer) control adjusts the opening of the air baffle between the two compartments. On E, the air duct is closed off all the way, on A it is open as wide as it can get. Normally, this should always be set on. C
Note: When the refrigerator is plugged in after having been unplugged for some time (such as at installation or after moving), it will take approximately 24 hours for it to reach optimum temperatures. During this time, the motor will run most of the time.
