Atwood Water heater problem
I have an 1981 28ft. The Red light comes on to engage the water heater, ,,,,,,,,and it stays on.
Indicating a problem,
Here is what I have done;
like to know and
what I have noticed.
Done: confirmed the board is getting power
cleaned the contacts from the wires to the circuit board. No Joy
cked for continuity front the wires to the circuit board. No Joy
Like to know. The board has power, ground, and 2 "valve" wires as well as one to the ignitor. These wires run to sensors on the tank inside coach. (I would attacha pic, but the paperclip icon above does nothing.)
IS THERE A WAY TO "FOOL" THESE VALVES TO SEE IF THAT IS THE PROBLEM? Would I heat one up, cross wires.
Do these switches HAVE to be attached to the tank?
What I have observed.
When powered up the circuit board makes a very slight high pitched noise. I believe this quits after lockout.
