Gas-cooking appliance controls work by regulating the flow of gas to the burners, ensuring safe and efficient operation. The primary components involved are the control knobs, gas valves, ignition system, and safety features. Control knobs are the user interface, allowing the user to adjust the flame size. When a knob is turned, it operates a gas valve, which controls the amount of gas flowing to the burner. These valves are typically of two types: manual and thermostatic. Manual valves allow for direct control over the gas flow, while thermostatic valves adjust the flow based on temperature settings. The ignition system is crucial for lighting the gas. Modern gas appliances often use electronic ignition systems, which create a spark to ignite the gas when the control knob is turned to the "light" position. Older models may use a pilot light, a small flame that burns continuously to ignite the gas when needed. Safety features are integral to gas-cooking appliances. One common feature is the flame failure device (FFD), which detects if the flame is extinguished and automatically shuts off the gas supply to prevent leaks. Another is the thermocouple, a sensor that detects heat from the flame and signals the gas valve to remain open. If the flame goes out, the thermocouple cools, causing the valve to close and stop the gas flow. Overall, gas-cooking appliance controls are designed to provide precise control over cooking temperatures while ensuring user safety through various built-in mechanisms.

Electric-cooking appliance controls differ from gas controls primarily in their mechanism of operation and precision. Electric appliances typically use digital or analog controls to regulate the flow of electricity to heating elements. These controls can be in the form of dials, touchpads, or digital interfaces. They allow for precise temperature settings and often include features like timers, pre-set cooking modes, and safety locks. The heat is adjusted by varying the electrical current, which changes the resistance in the heating element, thus altering the temperature. Electric controls can offer consistent and even heating, making them ideal for tasks requiring precise temperature management. In contrast, gas appliance controls are generally more manual and involve mechanical knobs that regulate the flow of gas to the burners. Turning the knob adjusts the size of the flame, which directly influences the heat output. Gas controls provide immediate visual feedback through the flame size and offer rapid temperature changes, which is advantageous for techniques like searing or stir-frying. However, they may lack the precision of electric controls, as the temperature is adjusted by eye rather than by exact settings. Safety mechanisms also differ; electric appliances often have automatic shut-off features, while gas appliances may include flame failure devices to cut off gas supply if the flame is extinguished. Overall, electric controls offer more precision and additional features, while gas controls provide immediate heat adjustments and are often preferred for their responsiveness.
