After cleaning, verify that the appliance is back in its normal operating mode and can maintain the required storage conditions before relying on it for chilled food. A bright interior light is not that verification.
What the observation tells you
The cleaning process may involve disconnecting power, opening the door for a long period and removing cold shelves. Those changes temporarily alter the cabinet conditions. A control might also have been touched during wiping. Check that removable fittings are back in their intended positions and that no cloth or packaging obstructs a door seal or internal air outlet.
A useful next step
Follow the model's cleaning and restart instructions, dry permitted surfaces and keep food in suitable alternative storage during the process. Check the selected setting and a settled thermometer reading. If cooling fails to recover or a warning appears, stop treating the problem as merely the expected aftermath of cleaning.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
