The Ariston air pressure switch enacts safety protocols to check if the fan is working correctly. It ensures that, if the fan fails within the boiler, there will not be a build up of toxic fumes with no means of venting them. The printed circuit board closely monitors the air pressure switch to make sure it is fully functional before the unit is fired up, preventing the appliance from starting without one of its key safety mechanisms.
