HI, My water heater isn't used much, even tho I'm full timing at the moment.  Worked fine before...now the red lite goes back on after about a minute.  I kept trying and now it seems to be working.  Is there any scheduled maintenece I should be doing? Any help would be appreciated.
Thanks, Larry

Hi Larry

From your description, the flame lights but then goes out shortly therafter.  This is usually due to some obstruction in the flame line, and this is due mostly to spiders - they are attracted by the smell of propane.  Get a narrow brush and brush out as much of the fire tube as you can.  Once the heater works OK, turn it and the water off and remove the drain plug - you should drain and remove any crud from the tank yearly.

Good luck

Larry...

I hope Gus's suggestion fixes the problem, but it sounds just like the problem we had with our 02 RB last winter while on the road.
The heater fires up, then shuts down after 45 seconds or so?

It was our WH's circuit board that had malfunctioned.  After a bit of a run-around, we got Atwood to replace it under warranty... if memory serves me, it ran around $150 for the part, which we got from a local Atwood-approved RV repair place.
 We did the work ourselves... er.. husband did.  Atwood had us first replace the heating unit (I forget the technical word), as it's the cheaper component, but that wasn't the problem.

Good luck

does anyone know the symptoms of when your temperature pressure relief valve on your water heater goes out? I have been getting leakage running somewhere in the walls of my motor home and coming out on the first step, as your stepping into the coach,I don't see no water in the water heater compartment, it only leaks when I run the water heater,I've done all the steps according to the manuel, nothing seems to work. I have a feeling it is the TPR valve, anyone have any suggestions?

Joe:
 After a time, the air bubble in the water heater gets absorbed by the water, and then, as the water heats, there is no place to expand to, so it weeps out the pressure relief valve.

Your book tells you to manually hold the valve open until no more water drains out (which reestablishes the air bubble), then shut the valve "with authority".
 My way of avoiding the problem is about three times a year when I hook up park water, I do it with the hose empty.  I then turn off the water pump and the hot water heater, and open a HOT water faucet.  I then go out and turn on the park water.  The air from the hose fills the hot water tank and the open faucet vents this air until the only air left has formed a bubble in the hot water tank.  Turn the water heater back on and eureka - you have a new bubble for several more months.

Hope this makes sense.
