Carrier 38HD Flame Sensor
A flame sensor is an important safety feature that can reliably detect the acceptable flame when igniting the system. As you would probably could have guessed, if the flame sensor senses a problem the entire HVAC system will stop until the problem is repaired.
Major signs your flame sensor needs to be replaced
- The heating system will start sporadically when the time is right
- The gas has a tough time trying to begin igniting no matter what
- Your system will not produce any heat when you crank the thermostat up
