Carrier 24ACA424A0030010 Flame Sensor
The flame sensor is an important feature that can reliably detect the flame upon ignition. As you would probably could have guessed, when the flame sensor is activated the entire HVAC system will stop until the problem is remedied and the system is reset.
Major clues of an unhealthy primary flame sensor
- The gas cannot ignite and the main board displays on error code
- The gas furnace is unable to ramp up when you want it to
- The entire heating system will sometimes work sometimes when the time is right
