Hi guys . My oil boiler motor and oil pump kept running but not igniting . So I fitted a new control box and photocell . The boiler fired up first time . But when the boiler get to temperature it cuts out as it should . The problem is it will not fire up again after its gone off at temperature. Its just runs the pump and motor again without igniting . I even fitted another control box and photocell but same happening . Only thing I noticed the oil pump does feel quite hot but this shouldn't effect its sequence to firing up ? It's driving me insane please help
