Treat it as part of the whole appliance's operating requirements. Do not assume the freezer can ignore the specified surroundings because its target is colder.
What the observation tells you
The compartments may share components and the manufacturer defines the intended installation conditions for the unit. A model advertised for a particular location should still be checked for its complete limits. Brand reputation or an owner's anecdote does not replace those specifications.
A useful next step
Use the exact climate and installation information when assessing a garage or utility room. Report seasonal changes in both compartments, and arrange appropriate advice if the location is unsuitable.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
