Having trouble with my Atwood furnace. The furnace actually lights, burns for a few seconds then shuts down. Repeats three times then shuts down for good. Then display of flashing LED light on circuit...

I just had a similar problem and it was the limit switch I had changed prior to this and still the same blinking light. So I called Atwood and they had me change the sail switch still the same problem so they said it was the board so I changed the board same problem. I talked to a rv tech and he said check the limit switch again by hooking the limit switch two white wires together and bypassing the switch the furnace runs then it is the switch. You can test for power on either side where the white wires connect also the sail switch will give you the same blinking light good luck
