Boiler keeps clicking !!!!

[nick barton]

When my Central Heating Boiler is working (Ideal Classic NF230) it is occasionally being interupted by a series of RAPID clicking from I THINK
the GAS CONTROL VALVE. The interupting bursts of clicking send the gas flames on and off !!
Am I to believe this is a sign of the VALVE Packing up ?
Or is it something quite simple i.e electrics ?

Any help would be appreciated...thanks

Could be a board fault or a valve fault but 1st check would be pilot size incase rectification probe is cooling due to the partial blockage on the pilot injector.

Hi, my boiler has just developed exactly the same fault - I'd be interested to know what happened to Nick Barton's...
