Whynter ARC-12SD Flame Sensor
The flame sensor is a contraption that can reliably detect the correct flame during ignition. As with any other safety sensor, when the flame sensor gets triggered by something the whole HVAC system will remain stopped until the problem is remedied and the system is reset.
Important signs your safety flame sensor is going to die
- The heating system will start on certain occasions whenever it pleases
- The furnace will not produce any heat and shuts down
