Does the fan run?? If so it may well be the aps, or it might be a blocked venturi, kinked pipes etc. If the fan doesn't run then its the pcb or fan itself. I would suggest at that point you call an rgi

check the air pressure switch either with a mutlimeter or by shorting it out. if this is okay the chances are it is pcb.

Powell30 is giving you all the correct information. It probably is aps stuck in normally open by sounds of it. However if your not competent you really shouldn't be undertaking work (as defined by gas safety regs) on your appliance.
Get an RGI in.

Which is why the majority of RGI's on this forum do not give information about working of flues, fans, aps, and other safety critical items.

Indeed. It never fails to amaze me when I read what people do, how much time and money they spend on changing the wrong parts, and often the problem is solved by a pro for under 100 including a service.
