pilot light won't light.

Gas boiler has been of for a couple of months as the flat was not being used, cooker works fine though, I've just tried lighting the boiler but it won't light, no smell of gas at all, so I'm thinking there may be air in the gas line, as the boiler was only serviced about 6 months ago, I have tried holding the pilot in for ages (an hour at least) but still no gas, do I need to hold it in for longer or is there something else I can try? cheers.

Is there a gas tap that is turned off somewhere on the gas pipe supplying the boiler?

That is one possibility.


Take great care with gas.

no, nothing turned off, I have just noticed a faint light now, not sure how long it's been there but gas is getting though, but the light goes out as soon as I let go of the pilot button, it's just too weak to stay alight, so I'm guessing it's full of air with a weak amount of gas mixed in, I've held it again for about an hour, does this sound like it's just a matter of keeping it pressed in until the feed is 100% gas and no more air?

More likely to be a carbonised pilot jet.

It'll be a call out job. If you don't know what you are doing with gas then it can be quite dangerous if you go taking it apart to fix yourself. It could be a seized gas valve. Replacing a fuse is fine, pressing the reset button is fine, changing the wall thermostat is fine, changing the external programmer is fine...but anything to do with the gas side you should leave to a qualified and certified gas professional.

so is air in the line not an option? as I have just had a service only 6 months ago.

no air isn't your problem if the pilot is that small & weak

sniggings

guess not then, just seems strange it was fine after the service, then off for a couple of months then a problem, was only thinking it was air in the line as that is what came up on my Google searches

unless you have a small leak & the gas was turned off at the meter there should be no way for air to get into the gas supply, think of a tap just because you don't switch the tap on you still have water as soon as you turn it on, but even if you had air in there it would have gone by you pressing the button for an hour (although i'm not sure how your managed to keep that pressed in for that amount of time)

it wasn't easy I can tell you :mad: it wasn't continuous, just stopped now and again to change hands.
