OP here with an update. Came back today after shutting the water heater off this morning and found it overheating again. I confirmed that it was indeed switched off and it was. Had to turn the breaker off to get it to stop heating. Double checked a couple of times but it does seem like the relay is stuck closed and providing constant 120v power to the element. Tried it a couple of times, breaker on and could hear the element heating. Can't get to it tonight but will pull the relay and check it but will be surprised if it is OK.
This is the second relay gone bad in 4.5 years of use so I may have to look for something that might work better. I don't know how to protect against something like this as switching off the water heater did not stop the heating.
Thought you all should know.

kind of late question but what model of atwood water heater do you actually have. Are there two switches (gas and electric) or just one?
ALL Atwood COMBO (electric/propane) have TWO on/off switches...one for electric and one for propane
OPs uses DC Circuits to operate BOTH.....the DC Relay triggers the 120V AC for the electric
2003/previous models use SEPARATE controls..120V AC for electric and 12V DC for propane.
