my IDEAL classic nf fanned flue gas boiler is not igniting.When the water is switched on the pump and fan appear to be working and the boiler sounds as if it wants to ignite. There is no sound when cental heating is switched on,that is there is no pilot light or any sign of life. Help me diagnose the problem before i am totally ripped off by a plumber.

Yes well I think your boiler sounds old and you wont get the spares, I can powerflush your system for 850.00 then sub out the job of fitting you a new combi you dont want for 5500.00 but you will get a free rad valve and a certificate from CORGI to tell you it's new and shiny, better still go down the pub and find some bloke who's had ten pints who "does a bit", he will be bound to be cheap enough for you.

forget i even asked.You obviously are not going to bother answering my problem.Terribly sorry I even bothered asking. I really did not expect this kind of response.I assure you I am not a customer from hell.I never question the workmen that come to my house. I do not quibble about the price. It would have made it easier for me to explain the problem to whoever i was going to employ. I'll just go ahead and contact someone fom the yellow pages.I really do not feel That I should have to grovel to get simple advice.

you could try to reset the boiler overheat stat if it was fitted with one...it's the red button on the side of the boiler control box.....are you sure that your room thermostat is calling for heat in CH mode?

Thank you ollski for your advice. My thermostat is set at a high temp so that it is calling for heat in CH mode.I set it as such to check if the pilot light would come on.There is a overheat stat control of some kind it appears to be a red screw. i would not know how to reset it.

it should just be a button to press....have you just switched your heating on for the first time?...it sounds like two different problems the heating probably down to you motorized valve not making a contact and the lack of ignition either down to the boiler overheat stat or possibly the air pressure switch.

the heating has been kept on at a very low thermostat setting throughout the summer.I only raised the temperature setting to check if the ignition would work.What is the air pressure switch?The problem only occurred this morning. The boiler is approx 9 years old.

The boiler starts in a pre-determined sequence when heat is called for. The fan starts, the pressure switch operates if the pressure is sufficient, the starter starts, the pilot valve opens, when a flame is established the main gas valve opens.

You should get someone with the necessary test gear to check it out.
