Carrier KFCEH2101F24 Flame Sensor
The flame sensor is an important safety feature that can reliably detect the acceptable flame when igniting the system. Because of the safety issues involved, when the sensor is triggered by an event the gas valve is shut off and the system halts until the problem is dealt with.
Major indications of an ineffective Carrier flame sensor
- The gas entering the furnace will not begin an ignition sequence no matter what you do
- The furnace refuses to begin working and spits out an error code on the main board
- The unit runs intermittently only
