AO Smith Water Heater FPS 50 Burner Fails to Light

Have an older AO water heater. Fan kicks on but burner fails to light. Fan just runs forever without burner on. Pilot light is on throughout.

Any simple fixes I can try? Suggestions? Thanks.

What gas valve is on that unit? Does it have a green blinking light on the side? If so read the blink sequence. Its most likely throwing a code and we would need this info.

If it is the smart valve variety I would strongly suggest replacing the heater. You would be throwing money away trying to repair IMO.
