Some models provide a mode with that purpose, but its exact behaviour must be verified. Do not assume ordinary chilled food can remain in the refrigerator section.
What the observation tells you
A normal freezer target can create false reassurance about milk, salads or leftovers above it. The compartments have different storage needs, and the feature may deliberately change only one. Another model's holiday button can behave differently.
A useful next step
Read the full mode description and remove food as required before activation. When returning, restore the normal settings and confirm suitable conditions in both compartments before restocking.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
