A flame sensor senses the furnace flame ensuring that ignition has occurred. It then monitors the flame until the furnace shut down. Should combustion be disrupted for any reason the sensor loses its signal and shuts the gas valve off.

    I needed a new flame sensor...................

    After cleaning my flame sensor twice after being 5 years old, I figured I should buy a new one. North American HVAC had a fair price, quick delivery, the package arrived intact, it was a good deal. Very relived to know I have extra parts if I need them.
