Hi guys,Just got back from camping and had water heater issues. 1995 Bounder with Atwood water heater. Wouldn't fire, red light stayed on. Checked connections and thermostat lead broke off. Bought a ECO/Thermostat kit and replaced both. Still nothing worked. Checked for power throughout and have it to board connector. Cleaned and checked the ground and the main board contacts. Plugged it back in and it fired. Quit after about an hour. Unplugged the main connector and put it back, fired on again. This kept happening on and off for 2 days. So I'm guessing the original board is bad. Thinking of putting a new Dinosaur board in. What do you think? Thanks!

Mike, Please post the Model Number of that Atwood. In the meanwhile there'll probably be a Service Manual on line at Chris Bryant's Site.

Thanks,I will post the Atwood model # tomorrow when I get home from work.

Mike if you go to the Atwood web site or manual if you have one it tells you how to test the board and other systems of the water heater just using a multimeter. You probably have a potted board if it is original and can't see the components inside if someone replaced it at some point it will be just a board with soldered components, you can look at the back side to see if any components are burned or any arcing in the tracks.

Thanks,It's the original board. I wonder if I remove it and take it to my local RV dealer if they could test it for me? I will call them tomorrow and ask.I was just wondering what you guys thought of the symptoms?

I think just by removing it you will clean the contacts and that might help you. If you haven't cleaned all the grounds and other contacts do that also. You say that it stays on for an hr then shuts off. This sounds like the water is being heated and it has reached the temperature of the thermostat and is being shut off(normal).

Yes, I cleaned the ground and the circuit board contacts.
I also checked the circuit board plug to make sure there is nothing wrong with it
What I mean when it shuts off, the red light comes on and it stops working again.
Until I go outside and unplug and replug the main board connector then it immediately fires and works for a random short time. But eventually the red light comes back on.
