Give each symptom its own timeline, then note any shared event. This prevents an older minor issue being mistaken for part of a new urgent fault.
What the observation means
A long-failed cavity lamp and a recent circuit trip do not automatically share a cause. The affected functions and dates are more useful than guessed parts.
A useful next step
Stop use for hazardous symptoms and provide the sequence already observed. Keep previous repair information available. Do not operate the cooker through every function to create a complete fault list before requesting help.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
