Furnace - Amana GUIA115A40
Control board - White-Rodgers 50A50-298

My furnace just has the fans running non-stop and the control board is flashing an open limit switch error code. The furnace is getting good circulation and both fans seems to run fine.

I cut power to it all night, in the morning I turned on power and instantly got the open limit switch error code. This leads me to believe the open limit switch is faulty.

Just to be sure, is the open limit switch a quarter-sized "switch" with a blue dot on it and two wires coming off it just above the burners on the left on this particular model?
