International Comfort Products MF20N2600A1 Flame Sensor
A flame sensor is a safety device that will reliable sense the appropriate flame during ignition. As expected, if the flame sensor senses a problem everything comes to a halt until the problem is remedied and the system is reset.
Subtle cues of a bad safety flame sensor

- The furnace operates infrequently barely
- The heating system refuses to even begin to start when you want it to
