Make and model of water heater?

Quick search shows you have a Suburban. Circuit board is easily available from Dinosaur electronics via Amazon.

I second the Dinosaurelectroics link..
When my Water heater needed a new board I did not have the time to order so I went with an OEM
But for my furnace I went with Dino boards.. I'm a trained electronics tech and the first thing I noticed was the QUALITY of the board.. (Way better than OEM) the next was.
Well as an electronic Tech I have a theory as to what killed the OEM board.. Turns out Dino shares that theory because they put a protective device on the board to prevent it from happening again.
