No blanket assumption is appropriate. Some issues involve shared controls, glass, supply or cooling rather than a single isolated zone.
What the observation means
Cracked glass, shocks, tripping and overheating require particular caution. A neighbouring zone producing heat does not clear those concerns.
A useful next step
Describe the entire symptom and ask for model-specific advice. Leave the hob unused for hazardous conditions. Do not continue cooking on a guessed safe corner or repeatedly change pans to discover which part of an unresolved fault can be avoided.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
