Treat the missing history as uncertainty rather than assuming the shortest possible interruption. A normal reading after power returns cannot show how warm food became earlier.
What the observation tells you
Clocks, alerts or other records may help establish timing, but they need to be reliable. The fridge restarting is an appliance observation; it is not certification that every food remained safe. Avoid using smell as a substitute for the missing information.
A useful next step
Consult the official power-cut advice and make cautious decisions about perishable food. Record that the duration is unknown when discussing the appliance. Do not invent a timeline simply to fit a storage estimate.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
