Potterton Profile 50el not lighting

[pruner]

I have a potterton profile 50 el gas boiler aprox 9 years old. It has been working perfectly until last night.

I noticed that the rads were not warm and on inspecting the boiler I found that the fan was running but the burner was not igniting. I have checked the reset button underneath and this appears OK.

I would be grateful for any advice on what the problem may be.

Thankyou

APS ? blocked pilot ? pcb ? gas valve ?

If fan is cycling, ie coming on and off every 20 secs approx its the board.
