Abstract
The temperature of a glass cooktop is sensed by an elongated thermistor rod positioned below the cooktop. The thermistor rod has a negative temperature coefficient of electrical resistance and is connected in a control circuit for the cooktop heater. The opposite end portions of the thermistor rod are located outside of the housing for the cooktop heater so that electrical connections to such end portions are not exposed to extremely high temperatures.
