Keith, I have the same WH in my truck camper, and started a Tech Issues topic on 3/4/19 regarding a similar problem I was having.
Atwood Water Heater Problem
At the time of my last post, I thought we had the problem licked, but the T-stat/ECO turned out to NOT be the source of the problem. Mine is shutting off, and then immediately turning back on before the water is fully heated up. It does that several times before finally shutting off for good when the water reaches 140*.
After replacing the T-stat/ECO switches, and confirming the problem still exists, I tried cleaning the connections again but that didn’t help. I eventually discovered that I could cause the WH to shut off/on by tapping on the igniter board with a screwdriver handle. In fact, one component on the board appeared to be especially sensitive.
Anyway, I ordered another igniter board and I wanted to pass along some info that may be of help to you. I was told that Dometic bought Atwood, and now Dometic is doing things differently with the parts. When you bought a new igniter board from Atwood, they included an adapter plug that converted the edge connector on the older WH’s to the pin-type plug on the new igniter boards. Now that Dometic is supplying the parts, that little $2 adapter plug has to be purchased separately. I’m currently waiting on an adapter plug to be shipped so I can finish fixing my water heater. :M
I’ll update my topic once I get the new igniter board installed.
