Properly Diagnosing a Gas Furnace Pressure Switch - HVAC

High Steam Pressure: A pressure switch in the steam chamber stops the burner if the pressure gets too high. If the burner continues firing even when steam flow is low, the boiler pressure can build and the vessel can explode. Low Water Level: A level switch stops the burner if the boiler water level gets too low.
