A favourite recalls stored settings, which may differ from the recipe you now intend to follow. Check the actual recalled mode, temperature and duration before starting.
What the observation means
A saved programme can outlive a change of tray, food quantity or preferred cooking method. It may also have been overwritten by another user. The familiar label on the screen is not evidence that every underlying setting remains the same. A useful comparison begins with those settings, rather than assuming the oven has become inaccurate because a named favourite behaved differently.
A useful next step
Review the recalled details against the current recipe and the appliance's guidance. If the settings themselves have changed unexpectedly, note whether other preferences or the clock were also reset. Avoid storing a new favourite as a workaround for unexplained overheating. A faulty cooking result still needs assessment when the correct mode and loading instructions have been followed.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
