Carrier KFCEH1901C20 Flame Sensor
The flame sensor is one of the safety features that can sense the flame upon ignition. As with most safety features, if the sensor produces an error the furnace cannot start again until the main issue is remedied.
Some warnings of a poorly performing furnace flame sensor
- The propane or natural gas has a tough time trying to start an ignition sequence and the board throws an error
- System will sort of operate sporadically but only on the third Wednesday of on months beginning on Thursday
- The heating system will not start when the control board tells it to
