Thanks for the input guys.
The coach is a 2015 Thor Siesta, and the water heater is a model GC6AA-10E. The contacts I refer to is the multi pin connector with various colored wires plugged in. If that is the relay then the answer to javelin’s question is yes. Problem is, I don’t see any way of replacing that connector as it seems to be integral to entire circuit board. I’ve read that Atwood got some bad circuit boards but I hate to replace the entire thing without being sure it’s necessary. Propane heater still works fine.
