Do not force it or lever against the liner. A package stuck in ice can tear, and a sharp tool can damage concealed cooling parts.
What the observation tells you
The sticking may follow a spill, wet wrapping or contact in a place that should have stayed clear. Ripping the food free removes evidence of the liquid source and can damage the packaging. Avoid direct heat or boiling water as a shortcut.
A useful next step
Protect the food and follow the model's permitted defrost or release guidance. If the pack cannot be removed safely, obtain advice. Afterwards, review the loading position and packaging condition.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
