Carrier 48GX042090300 Flame Sensor
The flame sensor is a regulatory sensor that will sense the correct flame when the system starts. As you would probably could have guessed, if the sensor goes off everything remains shut off until the problem is dealt with.
Signs your furnace flame sensor will not live much longer
- Your heating system will not produce heat and produces an error code on the circuit board
- The heating system will operate rarely at midnight, but only after the new moon following the fourth Monday of the month
- The LP or natural gas has problems trying to start an ignition sequence and the main board displays on error code
