A Southbend Range 4475-1 Flame Sensor with Wire & Connector detects burner flame status to maintain safe, responsive heating performance.
The flame sensor with wire & connector detects burner flame presence and signals the ignition system to continue gas flow only when proper ignition is confirmed. Its wire-and-connector design provides a secure electrical path and consistent signal transmission, which matters for safe operation, reliable burner performance and accurate flame proving.
The flame sensor with wire & connector may be wearing out if the unit shows ignition failure, intermittent burner operation or shuts off gas because flame is not consistently detected. Physical signs can include damaged wiring, a loose connector, corrosion, soot buildup or heat-related wear and environmental signs may include grease exposure, moisture or repeated high-temperature cycling.
