I have a rheem furnace, the burner will come on run a few seconds, and then shut off, The LED Panel has a constant green light, and a blinking green light. The blinking one is in the middle the orange light never comes on. Can I fix this problem or do I need to call someone.

Clean the flame senser.

I got it working I put a volt meter on it just for the heck of it to make sure everything was working, and the polarity was wrong, so I switched the wires and it's working like new. I don't have a clue how that happened but it did..

Thanks for the update. Glad you got it going.
