The air pressure switch acts as a safety instrument that ensures the fan is fully operational. It ensures that, if the fan fails within the boiler, there would not be a build up of noxious fumes with no means of venting them. The PCB closely monitors the air pressure switch to make sure it is completely functional before the unit is fired up, preventing the appliance from starting without one of its key safety mechanisms. 38MBR BI1376104
