Nordyne MS3BA042KA Flame Sensor
The flame sensor is a safety feature that can reliably detect the exact flame when the system starts. For obvious reasons, when the flame sensor is activated the gas valve is shut off and the system halts for as long as the problem remains.
Easy warnings of a poorly working flame sensor
- The gas that has entered the furnace finds it impossible to start an ignition sequence and some type of error flashes on the main board
- The heat system is unwilling to fire up and will shut everything down
- The unit will kind of run occasionally when it feels like it
