gloworm / glow worm ultimate 40ff boiler problem

[jammo]

Hi. Can any one help me please. It's getting cold in here!
Last night my Gloworm Ultimate 40ff boiler has given up the ghost. It only now makes a faint humming noise when switched on which I guess is the electricity just activating the system. I only have neon lights 1 and 2 illuminated in the PCB. That leaves 3 and 4 which are not illuminated. These indicate failed airflow (light 3) and Ignition (light4).
The night before when it was working. It did sound a little noisier than usual. A bit like the fan was in need of lubrication and sort of whiney. Sorry I can't be a bit more technical but could anyone out there point me in the right direction of what to do to.....Over to you experts and thank you in anticipation

Gawd!!
That was a quick reply. Thank You

How should I go about checking if the fan is stuck?

you need to remove the combustion chamer front , which is really a job for a corgi guy. Once removed , the seals need to be checked and once replaced it needs checking so as to ascertain a correct seal.

Hi again

I have given the fan a nudge and the boiler has sparked into life again. Thank you very very much. I must say though, the fan still sounds a bit noisy. Would you think it's on it's way out or is there any way of servicing or lubricating it etc. Once again Thanks for all your help
