Maybe a search online for a troubleshooting guide, or this overall atwood guide which includes other appliances Atwood
Also a check on you tube will give quite a bit of info on troubleshooting those units.
Good luck.

Clean the contacts on the circuit board with a white pencil eraser
Clean the electrode/flame sensor. make sure it is adjusted correctly.
Clean the burner area.
If running off battery, insure it is charged

RED LED Flashing 3X....Ignition Lockout Error Code
Circuit board WET?
Dry it using Hair Dryer...then try again
If it works you might want to consider a Relocation Kit
(Atwood KIT includes a NEW circuit Board WITH a plastic Bracket that lifts circuit board up....make your own bracket)
Relocation Kit...circuit board is generi........rnaces/7900 thru 8900 AFS, AFM, AFL, etc
If not WET....circuit board is at fault
Dinosaur Electronics Fan50Plus Circuit board for replacement
Better quality circuit board
Dino Fan50Plus

Mine did the same thing.
Circuit board. Replace it with a Dinosaur. Much better than OEM.
