Let aregistered gas installer sort it out//don't go using naked flames near gas(i.e. a cigaretter lighter)//

just ask for a universal thermocouple. (it may also be the gas valve, but unlikely)

Many thanks Ian i'll try what you said, do i need a thermocouple for this boiler or would another do the job

andy, July 2009
not if the thermocouple is burnt out, it'll need replaced.

Thanks for telling me if i get a fag lighter on the end of the thermocoupler would this trick it in to lighting many thanks

Probably a faulty thermocouple ( the part that senses of the pilot is lit)
