Hi,
A little help needed, been to above mentioned boiler today, running ok for small periods at a time. When I pull open the combustion cover the boiler works fine. So air in or out issue. I've checked venturi, cleaned heat exchanger and checked flue. Not sure its the air pressure switch as I don't think the symptoms would be like this. I feel that it may be the fan. The funny thing is I had same problem a few weeks back and fixed it, but for the life of me I can't remember what I done. G can't even check my invoices as I had customer go pay for it.
Anyway if any one had any ideas or confirmation that its the fan, it would help greatly before I order one
Regards

Perhaps ring vokera and ask what resistance you should have across the fan and then test it?

Marleyco are you GSR? Just asking as we don't give out gas related safety answers on here. If you are get in touch with one of the mods and get into the gas safe registered forum.

Yes, I am. Haven't been on for a while and didn't realise the change. I don't really like the vokera tech line. Last time they just kept saying venturi and it wasn't. They're just too sure for me.
