Jammer- are you saying your water heater has an adjustable thermostat
inside your trailer?? I've never heard of that....
Since the OP has the 2012 model we must assume it worked before.
I don't think swapping wires is a good idea. The best way to trouble
shoot this is with a meter and some more feedback from the OP.
As mentioned- the rocker switch on the WH itself might be off.
The tank mounted thermostat/hi-limit cut out might be tripped or burned
The heater element might be burned out (again).
Mine has a lone 120v outlet mounted behind the water heater.
The WH is plugged into it.
My first step would be to verify that outlet is hot and the WH is
Then check the rocker switch is on.
Then check for voltage on both wires (both sides) of the AC tank mounted
Those are the easy checks.
The final check is to check for voltage AT the element. That requires
removal of the burner tube so the element cover can be removed
and the element accessed. Check for voltage at the element.
There are photos of this procedure found in the FAQ/water heater forum.
(The photos are how to access and replace the heater element but the
procedure would be the same to access it and test voltage there.)
