[w.a.l.o.Baloney]

any suggestions on this?
boiler has lately been struggling to light,
but did eventually. has now reached point where it doesn`t
light at all.
fault guide says that if fan is cycling on and off then electric,
which it is now doing, then the electric control is suspect.
the pressure switch seems to be working when it is taken out.
surely, the pcb wouldn`t GRADUALLY fail.
any ideas?

if fan starts then stops after a few seconds then the pcb is the first place i'd look
