hi there does any one know why the fan runs on slow speed all the time
ive changed the pcb and pump(seperate faults) and noticed the fan is still running ?????

Is there power to the fan ?

the fan normally turns slowly but not normally noticeable without removing the combustion chamber cover. If the spur switch is turned off the pilot light will go out, there has to be power to the boiler at all times, for the fan to rotate otherwise the pilot will go out.
