International Comfort Products HXA236AKA1 Flame Sensor
A flame sensor is a very important part of the safety feature set that can sense the proper flame when the system starts. As with most devices used for safety reason, if the sensor goes off the whole system stops for as long as the problem remains.
Hints to watch for in a failing safety flame sensor
- The gas that has entered the furnace refuses to start an ignition sequence and the board throws an error
- The heat system refuses to even start when you crank the thermostat up
- The furnace will sort of operate sometimes when it feels like it
