Do not bend it back or assume it is an ordinary removable rack. Some designs incorporate cooling components or specific structural supports in that area.
What the observation tells you
Applying force may damage the liner or sealed system. A shelf that no longer supports food safely also creates a falling-load risk. An apparently small deformation can therefore require more than cosmetic attention.
A useful next step
Unload the affected area if safe and record the damage without further manipulation. Give the model and how the damage occurred. Sealed-circuit work is outside this service's scope, so the findings determine the appropriate next provider.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
