I have changed the board on my suprima at Christmas worked perfectly up to now. The Red light is flashing when I reset it tries to come on but does not ignite gas the igniter seems not to sound strong. After trying to light it gives up and tries again.

this could be the fan running and sounding ok but actually running too slow, to open the air pressure switch and fire the boiler, slightly open the door during the ignition sequence and if the boiler fires its probably the fan, if not it may be your air pressure switch, i think unlikely such a new circuit board to have failed but of course it is possible
