Not sail switch otherwise you would NOT get ignition spark and flame lighting off
Flame sensor (spark electrode) is used as return path for 'flame proving' Milliamp Signal.....electrical current generated by flame ionization (reification)'
Being just a few milliamps the flame signal can be easily inhibited by *soot/carbon on electrode
*tip dirty/loose connection on high tension wire
*dirty/loose ground screw (mounting screw for electrode)
*spark electrode position/gap (centered over 3rd burner slot---1/8" gap)
