I'm puzzled.

I have a 75 Avion with electric and engine water - water heater. Exchanger
works but not the electric. I changed the probe, verified the 110, at the
probe. How can it not work? Weak ground? I'm lost here.

Dean,

If you have power at the heater and it is not heating, then the heating element is probably open. If you disconnect the power and measure it as
resistance, you should get a low number like in the teens when cold. If that is not what you see, come back and someone will tell you the right
element to put in there.

A word to the, as yet uneducated, on the school of applying voltage to a
heating element not surrounded by water. Service life on the element so
exposed, is measured in seconds, not years. They burn out almost
immediately when the tank is empty, and you turn them on. No arcing or
noise. They just go open circuit, never to be used again.

I am not familiar with Atwood,m but there is usually an over temperature device usually mounted on the end of the tank. It shuts off the power if the
temp gets too hot. Get out your meter and see if it electrically is open. Some are automatic reset and some are mechanical (push the button) reset.
