Lennox 52M72 Flame Sensor economical solenoid design that minimizesThe Lennox 52M72 Flame Sensor is a critical safety component designed for precise flame rectification in high efficiency gas furnaces. Engineered for direct spark ignition (DSI) and hot surface ignition (HSI) systems, this OEM replacement probe detects the presence of a burner flame by translating it into a microamp signal for the integrated furnace control. Built with high grade alumina ceramic insulation and a durable stainless steel electrode, it
