Control System Circuitry for Appliances

A control system for appliances, such as an electric grill, air fryer, convection oven, induction cooker (e.g., wok), coffeemaker, etc. The control system comprises circuitry for controlling operation of the appliance, including a first safety component in the circuitry for stopping a function, such as heating a liquid or an element, at a threshold parameter, such as a maximum temperature, and a second safety component in the circuitry for stopping the function of the first safety component at the threshold parameter. The first and second safety components, preferably switches or fuses, are connected in series to establish a redundant safety mechanism.
