Use the recommended normal setting and the food's instructions. Selecting an extreme setting without a particular reason can change running time without solving a loading, door or measurement problem.
What the observation tells you
A stronger setting does not repair a damaged seal or turn an unsuitable appliance location into a suitable one. It can also make ice or packaging harder to handle. Special freezing modes have defined purposes rather than serving as permanent substitutes for assessment.
A useful next step
Check the intended setting and actual storage conditions. If the freezer cannot maintain them, investigate the cause rather than moving progressively to colder selections.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
