A programmed duration may have ended the cooking stage even though the physical selector remains in its cooking position.
What the observation means
Check for an end message, alarm or automatic-cooking indicator. A selector's position does not necessarily show the electronic programme's current state. The food may also need an independent check under its cooking instructions.
A useful next step
Return the controls to the position specified in the manual before arranging another normal use. If no timed programme was set, note when heating stopped and whether the display remained powered. Do not assume that a still-lit cavity proves the heater is operating.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
