1 have a myson orion fanfare 40si.in the mornings when i switch it on it wont ignite,but if i open the front & blow hot air on to the pcb ign board it will,is my ign board on its wayout or is my problem elseware. its only started doing this in the last two weeks. any information on this will be greatly appreciated
I had a similar problem with my Potterton boiler - it turned out to be a slightly blocked pilot injector - the poor flame was not quite hot enough to trigger the flame failure sensor circuit - cleaning the injector (new one) fixed it.
There may be a bad joint on the PCB - it does happen.
