RV Furnace retro circuit board 31501 holder

thingiverse

This is a retro kit for an Atwood Dometic furnace circuit board 31501 for an RV furnace. I printed this on its left side with 20% infill and supports. I used #6 x 5/16” screws for the board and to secure it firmly in place within the bay. The Long Story: I bought a 2016 RV in 2018 and immediately encountered problems using the Atwood AFMD30111 furnace. When it failed, I discovered that the circuit board was severely corroded, as if it had been exposed to water for an extended period. Following advice from the forum, I redirected the drain from the fridge above the furnace to the outside and installed a new board. However, four months later while camping, I found the new board corroded again. Upon further inspection, I discovered that a power connector had broken off due to corrosion. The forum suggested watching a video by Just Plain Common Sense titled "Atwood Dometic Furnace Problems Part II The Repair," which mentioned that Atwood Dometic created a retro kit for an obvious flaw in their furnace design. The video claimed that this retro kit would keep the board elevated out of water that pools through condensation or other methods. I attempted to contact the person listed in the video, but was unable to reach them. However, the person I did speak with said it is not Atwood Dometic's "protocol" to send out the retro kit and instead suggested visiting a dealer or repair shop. Frustrated by this response, I realized that sending me the retro kit would have been a simple solution to the problem. Instead, I had to find time, drive 140 miles, pay $50-100 for warranty repairs (a cost I shudder to think about without the warranty), and leave my RV with strangers. The last time I sent it in, they held it for a month and caused more damage than what it was being repaired for. With that, my 3D printer saved the day!!!
