WebJun 23, 2024 · A flame sensor at the burner end of the furnace gas manifold connection signals to the furnace that there is a flame. Without it, the furnace would not know whether a flame was present. Furnaces often have short cycles because of flame sensor failure as well. The circuit includes a flame sensing rod in front of the last burner. WebMar 1, 2001 · The flame acts as a diode and converts the ac signal to a rectified dc signal. The strength of the signal required to prove the flame, and therefore to keep the gas valve open, is dependent on the control module and varies from one control manufacturer’s brand to another. ...
