Lennox 12F19 Flame Sensor and Coleman 3100-20Q315 specificationsThe Lennox 12F19 Flame Sensor is a critical safety component designed for precise flame rectify detection in residential and commercial gas fired heating systems. This genuine OEM part is engineered to monitor the burner's pilot or main flame, sending a continuous microamp signal to the furnace control board. If the 12F1901 furnace sensor fails to detect a flame, it immediately signals the gas valve to shut down, preventing hazardous gas accumulation.
