Hi , can you hear the fan running and then the boiler trying to spark?
Hi , then it will either be that the fan is getting weak and on its way out or that the air pressure switch is on the way out.
Hi, thanks. Is this something we could do ourselves, or would you recommend a Plumber coming to do this? If you think we could do this, could you please advise us how?
Hi. It doesn't involve gas parts just electrical components . fan has four screws and the air pressure switch one or two .and . unfortunately I cannot suggest you do it yourselves as I don't want to be liable . take the boiler cover off . identify the an and air pressure switch and the connection and see if its something you feel competant to do
