An air thermometer describes its immediate surroundings, not the temperature history of every container. Food size, starting temperature and position affect how quickly an item cools or warms.
What the observation tells you
A large covered bowl and a small milk carton can respond differently to the same interruption. That does not mean the warmer food is safe while the air reading recovers. It also means a single moment of warm air after opening the door should not be treated as a precise measurement of the centre of all foods. Avoid using touch or smell as a substitute for the relevant food-storage guidance.
A useful next step
Use the thermometer to monitor the appliance and use official food-safety advice for decisions about food whose history is uncertain. Record the duration of an interruption, if known. Do not puncture sealed packaging simply to manufacture a comparison for a repair enquiry.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
