a very common problem with the flame rod (sensor) is that over time a thin layer of carbon will build up on rod and send a false signal to the ignition module causing it to lock out.usually you can pull it out and carefully sand the flame rod.reinstall. Make sure you have a good connection to board. And a good ground to furnace where rod holder is attached.
