I don't think anyone will give you advice on a gas boiler, too risky in case anything goes wrong, a registered corgi enginer definitley wont give you any advice without looking at the boiler.

Your best bet is to get it checked over by a Corgi registered engineer

I would recomend using boiler care;

Thanks for your reply,have an engineer coming next week to do a service.Was just wondering what the problem might be thats all and whether a new boiler is likely to be required.

Chances are it is the "thermocouple" not an expensive job !!

No I doubt you would need a new boiler, the are generally easy to repair unless it's an old one

Good luck I hope you get it sorted

Thanks guys,the boiler is about twelve years old and i thought it may be the thermocouple.Some one else said it could be a blocked jet?but many thanks guys was thinking sugar couple of grand for a new boiler which i dont need at the moment.:thumbsup:

be careful-friend had an engineer said def new boiler and they went for a loan for it as they didnt have money spare..anyway i got the guy i use to check it and he said yes it was old but repaired for £40!!!!
if they say replace get another opinion!

I agree, lot of boilers have a thermo couple that sits in the pilot light flame and as long as the flame is hot the thermo couple will keep the gas supply open ( basically ) but after a few years the ends of the thermo couple burn out ( from sitting in the flame day in day out ) stop working and the gas supply goes out. A new one is a couple of quid or so, from any decent supplier, or you can get a universal one from places like B&Q. I have replaced them myself in the past, it's a straight forward(ish) case of unhooking it from the pilot light end and undoing a nut at the other then fishing it out, it can be a bit tricky as it is basically a long thin copper tube (3mm diameter ) which is bent and formed round the other gubbings inside the service panel. The new one will have to be bent to fit, which is pretty easy as it's quite a soft and maleable material. A plumber/heating engineer type will prob charge £40-50 to do it for you.
