A numbered dial is often a cooling setting rather than a temperature scale. Its direction must be checked in the model instructions; the number alone does not tell you the food-storage temperature.
What the observation tells you
Confusion occurs when someone treats a setting of five as five degrees. Another model may use a different scale or have a separate off position. Marking the original setting before an adjustment helps you explain what changed. Avoid turning repeatedly through every position, because the cabinet needs time to respond and the results become difficult to interpret.
A useful next step
Find the control diagram for the complete model reference, make only the recommended adjustment and verify the resulting storage temperature with a suitable thermometer. If the dial has become loose, damaged or no longer has readable markings, report that mechanical problem separately rather than estimating the position from an online photograph.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
