Hi Guys , having a stupid problem with a Mexico super 2 CF 125, has been serviced, new thermocouple fitted, new multi function gas valve fitted, runs fine for maybe 24 Hrs. then drops out, have replaced T/couple again, same problem occurs any ideas what fault could be, thinking may have faulty (New) gas valve.

No just bog standard boiler, T/couple - Gas valve - Boiler stat Boiler (25/30 years old) as is normal working fine until shut down for service, now is a pain in the A.

No this is an open flue boiler so the bottom of boiler is open

Are you certain there is no TTB stat fitted?i take it pilot drops out,if no TTB what states pilot injector in ?

 

[lame plumber]

weak pilot flame and lot of local wind, bit of flame lift and out she goes, a perennial aga problem

Very good pilot, blue flame, nice flame on burners, nothing lifting off, very strange, runs ok for 24hrs, on & off on timer, then just drops out, waiting for a call back from Ideal, Tec dept. is swamped out on calls, so may get a reply of them tomorrow, Boiler as never had any problems wondering if I've been unlucky and had a couple of dodgy T/couples

Is the pilot nice & strong over the thermo couple when its burning, could be dropping out that way... Those pilot are so delicate!

25 /30 years old already, maybe the time to hint a new boiler, but I guess after spending money on that one they want to keep it going lol?

 

[jtsplumbing]

Well just had a call back from Ideal, tell me the only problem they get when replacing the T/couple is people using a standard universal T/c as they don't generate enough voltage, and the answer is to fit Ideals own T/C will give it a go next week

 

[Geyser]

I always use universal on them and not had a problem. But worth a try. Jobs like this are annoying!
