Carrier 38BYG042 Flame Sensor
A flame sensor is one of the safety features that can reliably detect the correct flame in accordance with the initial ignition sequence. As with other safety devices, if the sensor goes off the furnace will not start for as long as the problem remains.
Major indications of an inadequate Carrier flame sensor
- System will start sporadically when it thinks it should
- Your gas furnace is unable to start and produces an error code on the circuit board
- The gas that has entered the furnace cannot start an ignition sequence and closes the gas valve
