We had this happen a lot of rain & control board went crazy, the furnace is set to attempt to keep the pilot light lite & after 3 times it shuts down, pulled the control board out & ordered a dinosaur control board that is made in USA with 3 year warranty however I dried the Atwood board out & reinstalled & working good, & I have a new board Incase it goes out without the rain, the Atwood boards are made in China & are subject to going crazy when it get moisture from rain in it, to fix just remove & dry thoroughly & reinstall if it acts up after a bad rain. This will more than likely correct your issues
