the air pressure light is flashing on my boiler which indicates the switch is faulty so ive order a new one, although ive done some more tests inclueding testing the pcb (240v going to the fan on inginition) but the fan doesnt spin so i connected the fan directly to the mains but it still doesnt spin just makes a noise, so i was wondering if the air pressure switch is faulty will that cause the fan not to work or should it work regardless.....? im thinking the fan has gone....hope any of this makes sense,
if anyone has any advise please let me know cos im freezing!!
