Water Heater wont work in rain

[jesseannie]

We were camping on the Oregon Coast and during a several day rainy spell the pilot light on my Atwood water heater would not stay lit.
I had the pilot light tube assembly and the valve replaced and it worked, until the next rainy day.
I got it re-lit the following day (no rain) and it worked fine.
We moved to a new location and it started to rain and the pilot light went out. I relit it the next day. It worked fine for a couple of weeks even in cold and windy conditions.
Again a few days ago in the rain it went out and would not light until the rain stopped.
Other than not camping in the rain!!! Do any of you have any ideas about what is wrong??? The RV service tech thought I was crazy I think.

is the outside cover upside down? letting the rain flow right in.

Provided you have a 'Pilot Flame' type.....

Thermocouple 'PROVES' pilot flame is lit by generating milivolt signal (12 milivots or higher) to keep magnet latched allowing gas to flow to pilot.

Thermocouple getting shorted out due to rain...signal drops out ....magnet closes....pilot flame goes out


Now IF you have a Gas Only DSI type...
Then rain is getting on the ECO (red wires) and shorting out the 12V DC going to gas valve causing to close
OR
Rain is getting on wire from circuit board to spark electrode shorting it out causing 'PROVE' signal to drop out....circuit board shuts down gas valve


What is your MODEL NUMBER??????????

Is it possible that there is a leak and the rain is getting into the pilot light compartment and putting out the flame?
