There is a Primary High Limit Switch towards the middle of the furnace, it more than likely needs to be replaced, very common to go out only after a few seasons. Also, you could have a flame rollout switch tripped that will signal the same code, these switches are re-settable and are located on the outer, top and sides of the burner assembly, they’re about ½ inch in diameter with a red push button in the center and two wires “ usually purple” coming off of them.
Hope this helps
