A special observance programme can deliberately change normal lighting, timing or control responses. Check whether that mode is active before treating every changed response as a fault.
What the observation means
These settings vary substantially between appliances. Their duration, temperature limits and permitted user actions must be taken from the correct manual, rather than a generic online sequence. A control that appears unresponsive may be behaving as designed, but an unexplained burning smell, trip or overheating remains a safety concern regardless of the selected mode.
A useful next step
Find the programme name or indicator on the display and compare it with the owner's instructions. Use only the documented cancellation or completion procedure. Include the active mode when requesting help, especially if another household member selected it. Do not cut power repeatedly or enter hidden menus to make the interface behave like an ordinary cooking programme.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
