Carrier 38YKC048 Flame Sensor
A flame sensor is an important safety feature that will consistently detect the flame while the system is starting. As with most devices used for safety reason, if the flame sensor is triggered the whole HVAC system will remain stopped until the problem is remedied and the system is reset.
Easy warnings of a weak primary flame sensor
- The heating system is unwilling to begin operations no matter what
- System will start infrequently whenever it pleases
- Any type of gas that has entered the furnace will not even try to begin an ignition sequence and closes the gas valve
