Yet another, Atwood water heater problem
So, a week ago, the water heater started acting up. Sometimes it would work as it should, sometimes it would light and burn until the water was hot. When it did, it might not re-light when the water w...

The 'thermal cut-off' is a one shot fuse safety device that blows at 190*F and 'cuts-off' all DC power to circuit board IF a flame blow-back should occur. Flame shooting out of combustion chamber and up the side of RV is not a good thing.
Causing circuit boards to go bad :H It's just a thermal fuse.
AND obviously your OEM board wasn't the real issue as the new Dino board didn't solve problem (and thermal fuse isn't even in circuit)
You are having DC power issues. And they are prior to board because it isn't even trying or throwing fault light.
12V DC can check good but doesn't take much resistance to stop it.
Check terminal connections/spade connections on t-stat/ECO and especially the connector on board. Connections need to be clean and tight.
Same with grounds (on water heater frame, gas valve and electrode bracket screw and the one that is screwed down under circuit board)
On/OFF switch can have bad terminals/contacts also.
Which model of Atwood?
Need to use meter and follow path of 12V DC to see if it is even getting to board when it is not re-firing.
