First confirm the displayed sequence, selected compartment and whether any segments are missing. An ambiguous screen should not be used to make a confident temperature adjustment.
What the observation tells you
Some panels place shared indicators close together, and a photograph taken during a transition can be misleading. A damaged symbol or unit can add confusion. Do not infer that the refrigerator is genuinely operating at that negative temperature solely from the layout.
A useful next step
Check the exact display diagram and record the complete sequence. Use suitable independent storage checks while the interface is clarified, especially if food condition has changed.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
