Yes, "fails to light" suggests that the ignitor is "clicking". If so, the sail switch HAS to be good. If the sail switch is bad or for any reason it does not complete the circuit (low voltage, restriction in intake or outlets, etc), it will not allow the PC board to open the gas valve or fire the ignitor.
