International Comfort Products GPSM36L080F Flame Sensor
The flame sensor can only be found on furnaces that burn a gas. It is a safety sensor that can reliably detect the acceptable flame when the system starts. As you could guess, if the sensor produces an error everything remains shut off until obstacle is corrected.
