Abstract
An ignition control system for an appliance is disclosed. The appliance includes a gas burner, a user actuable valve for controlling a flow of fuel to the burner and an electrical resistance igniter for igniting fuel at the burner. The system includes a user actuable control interface having an off state and an on state, coupled to the valve operative to control the valve and provide a control signal indicative of the state of the control interface. The system also includes a controller having a timer circuit responsive to the control signal and a boost circuit coupled to the timer circuit. The timer circuit selectively activates the boost circuit for a predetermined period of time. A first DC power supply is selectively coupled to the igniter to provide power to the igniter through the boost circuit. A second DC power supply is coupled to the igniter and control interface.
