Identify the model, the compartment and its currently selected mode. A convertible zone should not be described simply as 'the freezer' without confirming its function.
What the observation tells you
Mode names and transition requirements vary. Food suitable for one state may be unsuitable for the other, and a display change does not mean the contents instantly reached the new condition. This capability must not be assumed on a model that lacks it.
A useful next step
Follow the exact switching instructions and move food as required before changing mode. Record any accidental selection. Check service suitability for the appliance format before arranging work.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
