Emerson Climate-White Rodgers 790-707A1 Flame Sensor

The Emerson Climate-White Rodgers 790-707A1 Flame Sensor confirms burner ignition by detecting the presence of flame at the combustion area after the start-up sequence. Its sensing rod identifies flame activity and transfers feedback to the ignition control, allowing the system to determine whether combustion has been established. Gas heating equipment used in HVAC systems relies on this sensing arrangement to monitor burner status and regulate the ignition process. Accurate flame detection allows the control section to maintain the required safety sequence and respond according to the detected operating condition during heating cycles.
