Overview
The air pressure switch is a safety device which checks the fan is fully operational. It ensures that, if the fan malfunctions within the boiler, there would not be a build up of toxic fumes with no means of removing them safely. The printed circuit board monitors the air pressure switch to make sure it is fully operational, it will restrict the appliance from firing up if this key feature isn't functioning.
