gloworm 40-50 boiler's not working!

[lmb15]

wonder if anyone can help?

i've got a gloworm 40-50 boiler. the pilot light ignites but won't stay alight, so no central heating or hot water.
i changed the thermocouple incase it was that, but no luck.the flame's a good size, so there's no blockage.
a friend mentioned it could be the gas control valve - does this seem a reasonable idea? or do i just need a new boiler?!
it's cold!

cheers.

Have you used correct t/c lead if so then maclaren gas valve has failed (very expensive & have just gone obsolete but there will be a few kicking about if you persevere)

cheers for that. new boiler it is then!

If it's a fuelsaver, then it's probably the fan

... which has a resettable thermal fuse which cuts in and out when the windings overheat

£45 for a fan must be cheaper than a new boiler

is there power to the boiler .. check !! the pilot will work with or with out power .

yeah, definitely got power going to the boiler.
it's a fuelsaver 40-50, so if it is the fan, can i change that myself or is it a tricky job that requires a person who knows what they're doing?!

cheers

easy job ..
is there live to the fan ?? it is a prosses of ilimination .. <<spelt wrong>>

someone told me yesterday that if a non-corgi registered person repairs a boiler and it goes wrong, that it invalidates your house insurance and is illegal. is this true?
sorry, i'm a bit clueless when it comes to boilers!

cheers

No it won't if it's got electronic ign

The fuelsaver has a sequence board which depends on a) the o/h stat to be short circuit, b) the fan to be working corrdctly and c) the air pressure switch to change over from the normally closed to the normally open position

it will then spark and open the pilot valve

had someone round to look at the boiler, and it's one of the really ancient ones that doesn't have a fan,and was told it's dead. i basically need a new boiler, but don't know any plumbers in the leicester area, neither do my friends.(guy who came out quoted silly money)

i am therefore looking for a non-cowboy, reliable, reasonably priced corgi registered plumber to fit a new boiler for me. if anyone knows of one who is in/near LEICESTER, i would be extremely grateful. (it's getting colder!!)

cheers
