Adding many items at once adds heat and can reduce circulation if packages are packed tightly. Plan space before loading rather than assuming a colder dial setting will compensate for any quantity of shopping.
What the observation tells you
Chilled shopping should be put away promptly, but it helps to know which items actually need refrigeration and which can remain in their normal cupboard storage. Large bags and outer cartons can occupy space that should remain around air outlets. Frequent door opening while deciding where everything goes creates another source of warming.
A useful next step
Read storage labels, organise the shelf space and keep the manufacturer's ventilation paths clear. Use a special cooling mode only if the manual describes it for that purpose. If the appliance remains too warm after sensible loading and settling, protect the food and describe the load change when requesting help.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
