Some touch controls need suitable contact from an uncovered finger. A glove, sleeve or thick protective layer can prevent the input the panel expects.
What the observation means
Controls should be used with safe, dry hands and without reaching across a hot door or steam outlet. Do not remove protection needed for handling hot cookware just to press a nearby control while carrying the dish.
A useful next step
Put hot cookware down safely first, then follow the panel's instructions. If ordinary clean, dry finger contact is also ignored, record which controls fail and which still respond. Avoid pressing harder or using a sharp object against the display.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
