Grilling can change food surfaces quickly, and a timer may only sound an alarm. Supervision is still needed under the appliance's instructions.
What the observation means
Fat, thin food and a close grid position can produce rapid browning or ignition. Automatic controls do not remove those risks or establish that the chosen cookware is suitable.
A useful next step
Remain attentive and use the specified door and pan arrangement. If you need to leave, stop cooking safely rather than relying on an unverified shutoff. Report an unreliable timer separately, and do not use it as the sole safeguard against a grill that behaves unpredictably.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
