International Comfort Products H9MPD100J20B1 Flame Sensor
The flame sensor is one that will dependably sense the precise flame while the system is starting. As you could guess, if the flame sensor senses a problem the furnace will not start until the problem is fixed.
Signs to watch for in a failing safety flame sensor
- System will kind of run occasionally barely
- Your system will not even begin to start no matter what
- The gas that has entered the furnace refuses to try to burn and the control shows an error
