The Worcester Bosch air pressure switch is a safety instrument which checks that the fan is fully operational. It ensures that, if the fan fails within the boiler, there will not be a buildup of toxic fumes with no means of venting them. The printed circuit board 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 instruments.
Fits multiple Worcester appliances
