Atwood furnace ignition lock out 2016 28’
I mistakenly posted this in water heaters, sorry.
Anyway, I had our furnace in our 2016 28’ go out in the AM after working the eve before.
We had a VERY bumpy road and heavy rain.
The furnace fan would come on and the furnace would light for about 4 seconds and stop. This happened 3x before completely shutting down.
The circuit board LED would flash 3x followed by 3 sec pause, indicating an “ignition lock out”.
Researching the forum brought a plethora of possibilities. Mostly a board failure kept showing up.
The board showed signs of water corrosion on it for which I will now caulk the door.
I have also coated ALL connections with dielectric grease.
I purchased a new Dinosaur replacement and it fired off immediately!
I have included old board and new board pics.
Hope it helps anyone else.

May I ask where you purchased your board at?
Thanks ..... My light is flashing. X3 red also and all other possibilities ruled out. Thank you
I bought one from a seller on Amazon but shipped by Amazon. It didn't work. I called Dinosaur and they talked me through diagnosis. When they asked for the serial number to send me a replacement, they had sold it nearly a year before. They honored the warranty anyway and reset my warranty to my purchase date.
Save yourself some trouble. Google Dinosaur Board and buy direct.
Buy direct from dinosaur.
