Carrier 38HDR018 Flame Sensor
The flame sensor is a safety device that senses the flame upon ignition. For obvious reasons, if the sensor generated a error the furnace will not start until the problem is dealt with.
Major warnings of a faulty flame sensor
- Your heating system cannot generate heat when you crank the thermostat up
- The whole system operates sporadically only
- The gas that has entered the furnace refuses to try to start an ignition sequence and closes down
