Abstract
An oven control system and a method are provided for controlling for a gas oven burner. A gas valve is operatively controlled to supply gas to the gas oven burner. A spark voltage supply is operatively controlled for generating ignition sparks near the gas oven burner. A flame sensing circuit coupled to the gas oven burner provides a flame status representative signal to a control processor. The control processor operatively controls both the gas valve and the spark voltage supply.
