ABSTRACT:
An improved electronic power control arrangement for a cooking appliance equipped with an automatic surface unit operable in a Fry Mode to heat a utensil to a steady state temperature range corresponding to the temperature setting selected by the user. Two error signals are established by the electronic controller as functions of the difference between the user selected temperature and the sensed utensil temperature. The controller controls energization of the automatic surface unit as a function of the first error signal during the heat-up phase to rapidly bring the sensed utensil temperature to the selected steady state temperature range and as a function of the second relatively larger error signal during operation in the steady state phase to rapidly return the sensed utensil temperature to the selected range if it should drop below the selected range during steady state operation.
