Ok I have 12v from the board at the Gas Valve terminals. I unplugged each one separately and only one solenoid is working...looks like I will be ordering a Gas Valve. Seem correct to you two?

I noticed that I do not have a bypass/shut off valve between my hot and cold outlets of the water heater. Am I "losing" some of my hot water to the cold side? It definitely looks easy enough to get a valve and close it to have separation of hot/cold.

If only one solenoid working the whole valve has to be changed. They do not sell the solenoid for safety reasons. Can shop around and find prices from $90 to $150 if you are changing it. Would take pictures to make sure the wiring will be correct.

Go to
In the Category drop down box select Water Heaters.
In the search box enter 3475.
White-Rodgers coil will pop up.
Order it, install it and enjoy your hot water.

Try digging around at PPL Motorhome parts site. RV Parts and Accessories for Sale - PPL Motor Homes
They had the single solenoid for around $30 but that was several years ago. It is a White-Rodgers part and it seems as though it was listed under the Atwood water heaters. Same solenoid. I may have the information at the MH but going to be several days till I can look for it.

I don't have time right now to research but I also posted this on too maybe five years ago. Might do a search there and see if you can find it.
