Sub-Zero Temperature Fluctuations


  • How much will the temperature change in a Sub-Zero?
  • What is a normal temperature variance in a refrigerator or freezer?
  • Is it normal for temperatures to fluctuate in a Sub-Zero?


It is normal for temperatures to fluctuate slightly (+/- 5°F) in a Sub-Zero refrigeration product depending on external influences. An open door, humidity, and room temperature can all affect temperatures.

  1. If the temperature is too high, try cleaning the condenser. For instructions, refer to Clean the Condenser.
  2. New groceries or warm food will raise temperatures for a time. Temperatures should return to normal after several hours.
  3. If the temperature fluctuations are extreme after cleaning the condenser and external influences are ruled out, contact Factory Certified Service to schedule an appointment for repair.
