The whole appliance's operation may respond to a significant freezing task, depending on its design. The timing provides context even when the complaint concerns the fridge.
What the observation tells you
A longer running period after a planned load is different from unexplained continuous operation. It does not mean a fridge temperature problem can be ignored. Record the actual load and selected modes rather than assuming the two sections are mechanically independent.
A useful next step
Follow the freezer capacity instructions and measure the refrigerator appropriately. If abnormal conditions persist under normal use, provide the paired timeline for assessment.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
