Its position can suggest where moist air is entering, but it does not confirm a particular failed seal or hinge. Describe the pattern before disturbing it.
What the observation tells you
Frost concentrated around an opening differs from a solid sheet beneath a drawer. Check for visible packaging crossing the seal and whether the door closes naturally. Do not scrape the gasket or hold it away from the frame as a test.
A useful next step
Take a safe photograph, clear only an obvious accessible obstruction and follow the model's frost-care advice. If the pattern returns, report its location and timing.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
