NipponAsia aftermarket Part 31501 Circuit Board Replacement for Atwood，31501 Ignition Control Board Replacement for DOMETIC Hydro Flame Corp,Compatible Models 85-IV 16, 85-IV 20, 85-IV 25.

First bx got damaged somehow but re-delivered next day other than changing wire end went in nice and works great so far nice it’s $60 cheaper than OEM part

Item works great but I had to modify the power input wire. The original board had a narrow gauge blade on the board so I had to change the crimped on connector. Worked perfectly whence modifications performed!

Does it work? After a fairly easy mod, by a professional?Yes!But in hindsight. Spend the extra 20$-30$ and get the correct part!If ur a DIY’er and pretty tech savvy good deal!If not…Buy the OEM part!!!!!!

Half the price of atwood. Works the same.

I finally got to try this board on a furnace rebuild. You do have to change the 12v+ power wire end from the smaller sized blade terminal to the larger one to fit the board connection, no big deal. But this board blinked an error code of 'no flame sense', yet I had just replaced the flame sense/electrode. Swapped out the board with a Dinosaur brand and it worked just fine. Too late to return this one.
