Main 24HE combi boiler problem

[omen911]

Hi, I wonder if you can help? My Main 24HE combi boiler has over the last few months been shutting off in strong winds. The boiler is in the loft on the gable that faces the prevailing wind. It has been serviced and the Air pressure switch changed. The flue does not appear obstructed and I am wondering whether the fan could be weak although the heating engineer said it sounded ok when he listened. I have looked through the burner window when the fault occurs and the flame is cut dead so I think the AP switch is working OK. Is the fan a known fault and can it be tested? I have tried the rather unscientific test of feeling the strength of the exhaust and it seems less powerful than my neighbour's but I realise this is an unreliable experiment. I don't want to replace the fan without good reason. Thank you.

probs best to get a registered GSR round for a 2nd opinion

you dont want to be replacing the fan at all, get someone in who knows what they are about.
