Stop applying tools and assess the situation safely. A surface mark and a puncture can have very different consequences, and photographs alone may not show the depth.
What the observation tells you
If there is suspected cooling-circuit damage, an unusual release, smell or loss of cooling, follow the manufacturer's safety guidance and obtain professional help. Do not test the hole with water, adhesive or another tool. Avoid ignition sources where refrigerant damage is suspected.
A useful next step
Record what happened and the location. Protect food separately. Do not conceal the damage with a patch before a qualified assessment determines the appropriate action.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
