Happy New Year to everyone!
I have a 2 year old natural gas water heater that stopped working a few day's before Christmas. I was sure it was a bad thermopile but I called Rheem's tech-line and they recommended to replace the gas valve. Just so happens, when I first installed it I had a problem lighting it so they had sent me a replacement gas valve. Sometimes God works in mysterious ways!
My question is, based on these pictures, why does the gas valve probe look so moldy? I have the temp set fairly high, way above a temperature that should produce mold growth.
Please share your thoughts, I won't lose sleep over this but I'm curious what you guys think.
Thanks,
Water Heater Gas Valve.

galvanic action
Galvanic action occurs when two electrochemically dissimilar metals are in contact and a conductive path occurs for electrons and ions to move from one metal to the other. One metal corrodes as its ions are deposited onto the other metal. ... Cathodes are noble, or stable, metals that are not prone to corrosion.
