62-23543-01 Furnace Burner Flame Sensor
The 62-23543-01 Furnace Burner Flame Sensor monitors the burner to detect whether or not a flame is present. If the sensor does not detect a flame, it shuts the gas valve off, preventing raw gas from dumping into your home. Over time, a flame sensor may lose its ability to sense the flame, even when the flame is present. -
