Anyone familiar with this boiler and come across something similar before?

The tech guys said it must be an external control. I'm not so sure.

New fan put in 3 weeks ago.

Colleague thinks pcb or gas valve, leaning towards pcb.

I have ordered a few different parts so hopefully its one of those.
 
Could it be the air pressure switch dropping in and out or the tubes leaking to the aps
 
Thats one possibility discussed today. I have ordered the gas valve and pcb and aps.

That'll cover it. My bets on flame rectification, it'll be the pcb or a knackered electrode lead.
 
New fan fitted by someone 3 weeks ago, hose on the back split. Couldn't even see it. Replaced pas as likely on way out.
