Its position and compatible accessory arrangement affect what it measures. A sensor stuck anywhere on a pan cannot be assumed to provide reliable control.
What the observation means
Adhesives, contact surfaces and temperature limits may be model specific. Do not substitute a household thermometer for a manufacturer sensor.
A useful next step
Use only the approved installation and cooking procedure. If the sensor detaches or gives implausible readings, stop relying on that mode. Retain its reference and describe the event rather than taping it into a new position or bypassing the warning.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
