Abstract
A kitchen appliance having a heating element and a control for controlling supply of electricity to the heating element. The control comprises a temperature sensor comprising a thermistor or thermocouple; an electronic controller electrically connected to the temperature sensor; and a user actuatable input connected to the electronic controller for selecting upper and lower temperatures for cycling OFF and ON supply of electricity to the heating element. For all of the user selectable upper temperatures, the electronic controller is adapted to turn OFF supply of electricity to the heating element when an output from the temperature sensor indicates a sensed temperature which is equal to or above the selected upper temperature plus a first predetermined temperature value.
