Broken Boiler. No Hot Water or Central Heating!

[Acrobabe]

Hi there,can anyone help me with what this problem might be?

I have a Glow worm Micron 30 ff and to start off with the problem was that the boiler turned on (meaning the pilot light was on and making a humming noise) but it didnt actually fire up to produce hot water or central heating. Now when the timer comes on nothing happens, no pilot light, no noise,no nothing!!! Help me i'm cold!

Your help is much appreciated!

Unfortunately it could be many things.

Humming could be fan seized or gas valve solenoid, or even a dry joint on the pcb. The change to no noises could be the fuse has blown, either 3A in the main supply or a fuse on the pcb itself.

Once power supply has been restored can you hear the fan running (hum) and feel air moving at the flue exit?
