Wink Why does gas fire pilot light keep going out ?

No , I am not going to fiddle with it but before I get the gas chappie who services our boiler to look at it I thought I might ask here first.
We have a Magiglo Custom 16 gas fire in the lounge and just recently the pilot light keeps going out. When re-lit it might stay on for days or just hours ! No strong wind, no changes in supply, everything as it has always been. The booklet shows a 'lint guard' that might need cleaning but I can't see one on ours !
Any ideas and YES , I will get a qualified person to fix it.

Cheers

Brian

Thermocouple or pilot jet needs cleaning. Why leave the pilot light on? Just turn it off when not in use.

Get it serviced by a qualified engineer!

Can be a sign that the thermocouple is on it's way out.

My dad's boiler used to do it........but HE insisted on turning the pilot flame up huge to stop it blowing out . with the result that it burnt the thermocouple

As said it could be either a weak thermocouple or the oxypilot assembly could have dirt/dust in it! Is the pilot blue or does is have a slight yellow tinge to it?

When it stays on, which it has for the past 24 hrs !!!!, the flame looks like it always has, blue at the base and a strong yellow top.
The fire has never cut out when it's been on and flaming, just the pilot that is a bit iffy.

Pilot should be all blue, the yellow top indicates a bit of dust in it! With the pilot off, get a tube or a can of compressed air if you have some and spray/blow into where the flame comes out. They are usually quite accessible!

It worked ! Thanks Mervil. It went out again yesterday so I used the vacuum cleaner nozzle and gave the pilot hole a good suck !!!! Re-lit and flame is all blue and has stayed on ...so far .
Hopefully that solved the issue, nice and simple.

No worries

That's the cause of a lot of back boiler and fire breakdowns I go to
