Strong-smelling food can affect an enclosed storage space when its packaging is unsuitable or poorly closed. Start by identifying the source rather than assuming the cooling system produces the smell.
What the observation tells you
An odour absorbed by packaging or a shelf does not establish whether food is safe. Check for spills and forgotten items, and distinguish an ordinary food smell from burning or an unusual chemical odour. The latter needs an appliance safety response rather than deodorising products.
A useful next step
Use suitable covered containers, clean permitted surfaces and keep storage dates clear. Avoid masking an unknown smell with fragrance. If the source cannot be identified, describe its character and when it appears when seeking advice.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
