Describe the surface issue and operating change independently. A scratch, bent trim and failed control are different problems even after one incident.
What the observation means
Appearance does not prove safety, and a working burner does not rule out damaged connections or supports. Conversely, a finish mark does not identify a failed heater.
A useful next step
Keep the incident and observed effects clear. Stop use where damage affects handling, controls, glass or supply. Do not cover a mark before assessment if it helps explain an impact or overheating event.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
