Abstract
A cooking appliance includes an oven cavity, an electric heating system having a plurality of electric heat loads for heating the oven cavity, and a controller. The controller includes a memory module having stored therein at least first and second control algorithms for operating the electric heating system based upon an available current supply. If the cooking appliance is connected to a low current rated circuit, the controller will operate according to the first control algorithm and cycle activation of the plurality of heat loads in a manner not to overload the available current supply. Conversely, if the appliance is connected to a high current rated circuit, the control unit will operate according to the second control algorithm and enable activation of multiple heating loads simultaneously. Preferably, the appliance includes a switch or sensor for toggling between the first and second control algorithms.
