Confirm that the model supports independent switching and that the symbol really means off. A display-selection or missing-segment issue can otherwise be misread.
What the observation tells you
The appliance may still be electrically live even if a compartment's cooling function is disabled. Frozen food needs immediate appropriate assessment if the freezer has genuinely been off. Do not use the apparent state as permission to work on internal parts.
A useful next step
Read the exact control description and record both settings. Seek clarification if the state is unexplained, while protecting the contents rather than waiting for a clearer symptom.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
