I have a baxi solo which a friend has asked me to take a look at i am boilers registed but mainly work on cookers the fault is the fan runs but there is no ignition.
Check air pressure switch and that the tubes from it havent become twisted, located at top of boiler. poss ventury block or air pressure switch has gone. Does the pilot light on control light up?? if so poss blocked pilot injector

I am not qualified or experienced - so don't expect wisdom.
Ignition is conditional on the fan running - a pressure switch senses the correct pressures in the enclosure and signals the control electronics accordingly.
Good luck...

check the ventury on the fan is clean and the air pressure switch after that could be the PCB
