    Gas Pilot light gone.............................out :( Why?

    My mum and dads pilot light for their gas has gone out, every time they re-light it goes out. Does anyone know whats wrong? They have only had their new radiators a couple of months but they have always worked fine until today.
    Any help would be appreciated...I don't want them gassing themselves.

    Usually its the thermocouple that's gone on a boiler that has a pilot … Usually its the thermocouple that's gone on a boiler that has a pilot light



    Thanks for replying, is that something they could fix themselves do you know or is it best to get someone in to do it?

    Is it snowing where they are? Snow/Ice may have blocked the flue, preventing the system from starting.

    He did mention that he thought it could be something to do with the cold. Its very icy in Norfolk. But at the moment we are not sure.

    It is possible but Gas Safe regulations forbid unless you are qualified and it and its not wise to take chances with gas. Look in your local paper for a GAS SAFE (Previously GORGI) registered heating engineer or you could always phone British Gas (not cheap though)

    The pilot light is normally kept alight by the thermo-coupling device. The heat from the pilot light heats up the thermo-coupling device (and the end burns like a red hot poker). It's this heat that keeps the pilot light lit. When it stops working or doesn't get hot enough the pilot light will go out because there is nothing to re-ignite it. Sometimes a good clean can give a short term solution but they should have it replaced by a qualified gas engineer. The bit they need is fairly cheap, it's the call out charges and rip off cowboys you have to watch. Good luck to them especially in this weather at this time of year. :santa:

    Thanks Philhib, it may just be the cold weather, I didn't realise that it only lit itself when the heating came on (turns off at night) and the pipes are all outside so maybe it will just end up being that....hopefully

    :santa: Rep left to you all...hopefully the heating will get sorted out tomorrow. :thumbsup:
    Merry Christmas to you all x

    How long are they holding in the button when they try and relight? You need to hold it for at least 30 seconds before you release.

    like most people have said almost definately thermocouple. will take a gas engineer about 15 mins to replace so reckon you will look at about £40 and £10 for the bit. but definately hold the button down for a while before releasing as it works just like your gas oven, the metal tip has to feel the heat so it knows there is not just unlit gas pouring out.
    good luck

    I just normally light the pilot with a lighter whilst holding the button down then release the button slowly - (its an old boiler).

    On the new one the pilot just reignites itself once the boiler has been switched off then on again and the hot water tap is turned on
