Product Information: The air pressure switch acts as a safety instrument which ensures the fan is in full working order. It ensures that, if the fan fails within the boiler, there would not be a build up of toxic gasses 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 features.
This part is present in 11 different boilers in the Glowworm range including the Glowworm FUELSAVER UFB F, ECONOMY PLUS 24F , ECONOMY PLUS 30F , ECONOMY PLUS 40F , ECONOMY PLUS 50F .
