Carrier 38TKB042 Flame Sensor
A flame sensor is one of the safety features that will consistently detect the flame upon ignition. As expected, if the flame sensor gets set off the whole system stops until the problem is fixed.
Some warnings your furnace flame sensor is in need of replacing
- The gas cannot begin an ignition sequence and shuts itself off
- System turns on sometimes but only on the third Wednesday of on months beginning on Thursday
- Your heating system cannot work at all
