Review reliable supply or appliance alerts and assess both food compartments using official guidance. A running appliance on arrival cannot establish continuous operation during your absence.
What the observation tells you
Frozen food may have thawed and refrozen, while chilled items may look unchanged despite unsuitable storage. Informal tricks or appearance alone cannot reconstruct the history reliably. Do not taste food to resolve the uncertainty.
A useful next step
Record what is known and treat missing information cautiously. Check the current settings and warnings, and arrange appropriate food decisions separately from investigating any appliance or supply problem.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
