Why is a Sub Zero Freezer Temperature Fluctuating?
Temperature fluctuations are normal in all refrigeration systems. The only difference brands have, is the quality of the products they make. If you choose a reliable and reputable brand like Sub Zero, you won’t have any trouble with temperature fluctuations because the controls can regulate the temperature. But, it does not mean you can avoid inconsistent temperatures.
Check out why your temperatures are inconsistent and how you can fix the problem:
*Check if your vents are blocked.
*You might have adjusted the temperature settings.
