The timing is relevant to the responsible professional and needs assessment. It does not prove a particular adjustment is wrong, but it should not be ignored.
What the observation means
Keep the work record and describe which burner or function changed. Do not compare internal fittings with an online diagram or attempt to reverse the work yourself.
A useful next step
Stop using an abnormal appliance and contact the appropriate provider. Use emergency guidance for gas smell or immediate danger. Do not continue cooking for several days to see whether a persistent combustion change settles naturally.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
