Claims3
A method of controlling the operation of a cooking appliance having a cooking cavity used for at least toasting a comestible placed in the cavity, at least one heating element connected to an alternating current source of electrical power and a control circuit mounted in a separate control cavity comprising the steps of:
- sensing the temperature of the control cavity;
- providing the user of the appliance with a timer control for establishing a nominal time during which the heating element is connected to the alternating current source of power;
- varying the nominal time in inverse relation to the temperature in the control cavity;
- and
- delaying activation of the timer control in direct proportion to the period of time elapsing between consecutive toasting cycles.
