Abstract
An improved system for control of a gas oven appliance is provided. A valve provides for control of the flow of gas to the burner. After preheating the oven, the valve is cycled between high and low (or zero) gas flow rates at frequency that provides the overall desired heating rate of the cooking chamber during cooking operations. A variety of valve types may be used including proportional types and predetermined set point types (e.g., high-low, high-medium-low, or on-off). During cooking operations, between periods of cycling, the valve is at least partially closed (e.g., set to a lower gas flow rate or an off state).
