i have replaced fan thermastat air flow switch pc board the fuse is ok but still nothing happens when i switch on.I would appreciate any help regards Graham
do you get any sequence of ignition? does the fan run? the only part that often fails you havent changed is the gas valve and they are not available, more detail of how the boiler is failing would help pin point the problem

the 10-16 is the sort of boiler a diyer should be playing around with if you haven't got a clue.
you shouldn't even be in the combustion area.
by what you have done i would say on this boiler you have made the problem worse.

Having spent so much on spare parts - I hope you have not thrown them away - invest in a multimeter (£10) and check to see if the gas valve is being called upon to open.
