No. The system is designed to manage frost under its intended operating conditions, but abnormal moisture entry, blocked airflow or a fault can still lead to ice.
What the observation tells you
The label does not justify ignoring a door left ajar or a heavy build-up. It also does not mean all panels are safe to remove for cleaning. Different designs have different owner procedures when excess ice is present.
A useful next step
Check loading and closure through normal access, document the location and consult the exact instructions. Persistent ice or poor temperatures needs assessment rather than assuming the appliance must simply need manual scraping.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
