Ideal Classic FF260 - Whistling (Our new alarm clock!)

[stanjacko50]

The boiler failed a couple of weeks ago as the fan had stopped turning.

Called out a registered heating guy who fit a new fan and carried out a full service for me - great.

However, ever since the new fan, the boiler has been whistling loudly on startup for maybe 30 seconds, and does the same everytime the boiler re-lights. This resonates round the pipework and can be heard outside too.

I've found the cause but don't know how it could be cured. If I loosen the screws on the boiler cover and pull it out away from the boiler, or remove it altogether, the whilstling stops. It seems to be an air flow issue. Perhaps the new fan is more powerful than the last? The whistle only happens when the cover is in place so must be caused by a lack of air to the fan?

Any thoughts/ideas would be gratefully received - the chap who fit the fan can't come back till the new year but it can't be hard to fix?!

Cheers

The advice here is firstly not to operate the boiler with the cover removed or loose.
Then call him back to sort it for you.

Thanks but I'm not a complete idiot. I wouldn't dream of leaving the cover off or even loose, it was only in the name of diagnosis, and I wouldn't have done that had I not seen the gas-safe guy do exactly the same during his visit.

Any suggestions as to possible fixes? It's -5 outside so we can't have the heating off over Christmas but the whilstling is driving us nuts!

Not suggesting that you are.

If your engineer has fitted a new fan and now it is whistling he should be sorting this for you.

It's not a diy fix.

Could be just a damaged casing seal
