This could be caused by a failing igniter. Do you have an ohm meter?

Ok, then disconnect the connector to the igniter and probe the connections. A good igniter should read between 50 & 200 ohms. If it falls within that range remove it and check for any defects no matter how small. A little white powder is ok. Don't touch the surface of the igniter with your bare fingers. Hold it by the ceramic insulator. If the igniter test outside that range or has any flaws at all then replace it.

It should be replaced. Where can I find the part number? There is no markings on it.
Expert:  Rick replied 1 year ago.

Take it to a plumbing supply house. They're likely to have a generic replacement.
