ABSTRACT:
A method and apparatus is provided for detecting and responding to foaming of a fluid being heated, and more particularly, for operating a device having a container with fluid therein, wherein a resistance of an electrical path from a probe is measured through the fluid to a ground resistance. In operation, a control probe having a foam detecting conductance microcontroller module shuts off the device based on a predetermined volatility/variability of two or more resistance readings, because such may indicate the presence of foam in the fluid.
