Atwood Heater - Red light stays on!

[Moonstruck]

Hi Guys!

full-time living in an Airstream is a little different. I've just RETURNED from a weekend away at my girlfriend's to find my water heater pretty much dead except for from the ignition light in the bathroom. The heater is only a year old, very clean and no corrosion.

After reading a few troubleshooter pieces I'm coming to the conclusion that it's the board. That could just be wishful thinking as I did take the precaution of getting a replacement on my last spares shipping.

I could fit the board and see what happens but I'll wait until the morning as it's dark here and tipping with rain.

Can anybody suggest/confirm my diagnosis?

Marc,
try this first (since this won't cost anything): remove, clean and reinstall the little contact points found just inside the burner tube, as well as its mounting area (to make sure it is getting a good ground). If a spark is not produced, the starting sequence will shut down (turning on the red light)......I have to perform this little ritual at least once a year.

Just thought that I'd ask, but our red light comes on our water heater when we're out of propane!

Check out that any other propane appliances are working properly.

P.S cool pics! Glad to see vintage units on the other side of the pond!

Thanks for the suggestions guys!

The trouble-shooting I've checked was peppered with suggestions about corroded terminals. As I said the unit is less than a year old and very clean but I have removed/replaced all the "spade" terminals and I will check the burner connections before proceeding. My first thought on my return was the gas but I've cooked a curry since and it's all going strong.

btw, I've also fired up the Suburban NT 30 furnace to confirm that the 12 volt amperage and the gas pressure are fine.

As I've said, the unit seems dead. I've checked the connections with the power on but there's not a hint of arcing except from the fuse on the board.
