Chaffoteaux & Maury Combi SE 80 Boiler won't light

[scotf1]

Hi Guys,

The boiler is working fine but won't light. There is no spark to light it, does the spark generator need replacing or should i replace the PCB board?

Thanks in advance for the help.

get an rgi in. if the fan runs but no spark this could be numerous things.usually with these its the pcb thats the cause of this. low voltage to aps. but does take an rgi to set up.
