The air pressure switch acts as a safety device which 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 in full working order before the unit is fired up, preventing the appliance from starting without one of its key safety features.
