Treat these as two specific observations rather than assuming the whole appliance simply needs a warmer or colder setting. The control and airflow arrangement matters.
What the observation tells you
A local frozen item touching a cooling surface may coexist with a separate freezer loading or door issue. A shared fault may also produce unequal results. Neither possibility can be confirmed by the target values alone.
A useful next step
Record positions, both settings, the exact warning and recent loading. Use appropriate food-safety decisions and seek assessment. Avoid changing both targets repeatedly in opposite directions.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
