atwood water heater

While the OP's punctuation sucks, and shows real lazieness, it is still easily readable, or much better than some of the text I see here.

As far as the heater problem, I can see a voltage......or even a hi amperage problem,......like the gas valve drawing too much current ??

Here, have some periods on me. ..........

ECO is Emergency Cut Out (A high temp thermostat T-Stat is the operational (120 degree) Thermostat

Make sure the TPR (Temperature Pressure Relief) Vlave is not dripping on them, if it is, plumb the drip away from them.

Huh?

When replacing the set of t-stats the tank contact area needs to be clean AND the t-stats need to be tight against tank.

Now if above has been done and t-stats are failing......then excessive AC ripple could be the problem.
AC ripple is result of converting AC to DC...how much depends on diodes/capacitors.

To measure....test DC supply voltage at water heater. Then swap meter from DC to AC and measure......anything more than 1 volt AC could be why you are going thru t-stats.
That means converter is not filtering the AC ripple out.

Can you please type that in English? Thank you.
