Follow the repairer's and manufacturer's restart guidance and confirm suitable storage conditions before restocking. Completion of mechanical work is not the same moment as the cabinet reaching its operating condition.
What the observation tells you
The door may have been open and the appliance disconnected during the visit. A changed control setting or a newly fitted component may also require the stated observation period. Do not fill the cabinet with warm items to test it.
A useful next step
Keep food appropriately stored until the fridge is ready. Record the setting and a suitable temperature check. If performance does not follow the explained recovery pattern, contact the repairer with the observations.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
