2017 Greyhawk 29MV, AFMD30 furnace.
The control board sits right on top of a horizontal surface, which traps any moisture and destroys the board. I had weird, intermittent behavior and discovered this (see pic below, left).
In my emails with Atwood, the pic was sent, and they are sending me (gratis) a new board with a relocation adaptor that should prevent re-occurance.
P/N for the kit is 32596, available directly from them. (see pic below, right)
