Recently noticed our furnace will kick on, fan or blower (1) is heard, a clicking sound which starts the furnace fan or blower (2) then the another click and the burners kick on. After a few seconds, another click and the burners will shut off but both fans are on. Then a click and fan/blower (2) shut off. After a few more seconds a few clucks, fan/blower (2) will start up again followed by burner... few seconds later it shuts off and it starts over. The only way to get this to stop s to allow everything to shut off including fan/blower (2) and when all is silent, things will be fine until an hour or so. Then the series of clicking on and off will happen.

Hi Kim and welcome, I would try cleaning the flame sensor with steel wool. Let me know how that goes. Good luck

parttime nailed it. You need to clean the flame sensor. If that fails to cure the problem, let us know.
