Re aga keps going out.

Postby nina on Tue Feb 06, 2018 8:03 am

Have just had the yearly service of my converted gas aga. The engineer changed the thermocouple. Now the aga is cutting out when it gets beyond a low temperature. It wont even relight when I press the red button I can clearly see a spark but it wont ignite.
I have had problems in the past where the thermocouple was burning out every few months and I went through 5 thermocouples in a year. for the past year it has behaved itself and my engineer said it seems to prefer the Mark1 thermocouple.
My engineer advised me that if it wouldn't respond to the ignite button to unscrew the glass window at the front and light it with a taper. He did this yesterday. because it wouldn't light via the ignite button. Luckily I am on a service contract so he should return within the next few days (I hope). I really want to ensure that it lights via the ignite button as I am not that adept at unscrewing the glass .
My question is what should my engineer be doing to ensure it ignites correctly and in your opinion does a thermocouple need replacing yearly if the aga is going well? My engineer said to replace it year as it saved the aga breaking down.
As always I am very grateful for your help and advice.best wishes.

Sounds all too familiar viewtopic.php?f=2&t=2600

As for the piezo ignition they can be very hit and miss on the conversions and it is often safer to light with a taper through the sight glass. Having said that if you are getting a good spark at the pilot it should ignite providing there is a good supply of gas there.

Most manufacturers advise replacing the thermocouple every year, in reality probably not necessary but you are no doubt paying for one anyway so no harm in replacing it.

Indeed,
Recent and almost identical !
Have a good read through the recent thread , then tell us if your situation is different .

Thank you both for your clear advice and help, your website is a godsend.
My engineer came back and said on re checking the pilot there was a little debris in it which he hadn't noticed before and was preventing a nice flame to feed the thermocouple. Its funny perhaps through observation over the years I had a bad feeling about the pilot when he left the first time, because although the tip was glowing, the flame sounded a bit spluttery and wasn't even. He also bent the thermocouple tip slightly so it was right in the middle of the flame. I have come to dread the change of thermocouple because in my experience at least every other time the aga starts cutting out and there are weeks and months of calling the engineer back the usual problem is the thermocouple burning out after a few months.
The thread you directed me to sounded a complete nightmare but very like my own issues. thank you for that.

Hello
My aga went out again, the cause a burnt out thermo couple it has burned out in only 2 months my engineer said it is because gas conversions are temperamental. I did mention that the flame should not be too fierce but he said it’s the same flame as before when the aga went for 12 months trouble free.
We also found that the ignition lead had sheared off and my engineer said it may not be possible to get a new one as they aren’t being made anymore. I’m not keen on having to unscrew the glass window to relight it when it next goes out as it will inevitably.
Would anyone be able to tell me where I might be able to get hold of one?
Many thanks once again for your help and advice

Are you able to post a picture? Either of the electrode or the burner with the glass window.

Would be very interesting to see the burnt out thermocouple tip too but I imagine your engineer took that away.

Thank you for your quick response and hope I have uploaded the photo correctly. A couple of hours ago I see that the aga has gone out once again and I will have to wait another 3 days for the engineer to return. The new thermocouple has lasted less than 24hrs. Looking at the flame last night I did think it looked slightly more feeble than usual and was worried about it.
My engineer seems to think that converted agas are just temperamental and says he goes to one house we’re he changes the thermocouple every 3 months or so.
I don’t buy this as with my previous engineer the aga worked reliably for many years.
I am afraid he took the burnt out thermocouple away so I can’t send you a photo.
I am so fed up that I am thinking of getting rid of my aga and replacing it with a new one. The inconvenience is made worse as the control box is in a kitchen unit flush with the aga which has to be completely removed and then put back afterwards.
If anyone can recommend an experienced converter gas aga engineer in the London area I would be hugely grateful. I have managed to relight the aga easily on 2 occasions but after getting up to temperature it went out after about 12 hours or so. Now the pilot will not light at all. rather it lights up but then goes out.
My engineer is coming on Monday with a new pilot assembly any view or help you can give me would be hugely appreciated.

I have not been able to upload the images because I keep getting a red message saying the file is too big even my computer savy husband can't manage to do so. Any tips re this would be great.
Best wishes
Nina

I think your doubts about this guy are well founded. There is no reason why your gas converted Aga cannot operate as good if not better than a purpose built Aga.
I cannot recommend an engineer local to you sadly but no doubt there are several. Perhaps try speaking to any local Aga refurbishing companies and see if they can suggest a suitable engineer.

ps. not very clever with uploading photos myself but I think you need to re size the images by using photobucket or something similar?

Thank you I will try to upload the images.
Many thanks Is there anything I should mention to my engineer when he comes?

I agree with escorts assessment of your engineer. There is no reason why a conversion cant work well but the burner is in a harsh environment so the jet needs to be cleaned / replaced occasionally. It is not uncommon either for scale to form in the pilot pipe which can give rise to contamination. But if the pilot assembly and thermocouple are renewed then the problem should be cured.
If your "engineer" fails this time, then I would discuss with Sandy at oilwarm ( who supply all the necessary spares) and maybe he will know a decent guy in your area who is familiar with the product and its foibles
WRT uploading, the simplest way is to take the pics with your camera set on its lowest resolution. They should then be about 300K which is a doddle to upload .

PS Which part of London are you in?

Hello John

Once again thank your giving me advice on your day off I appreciate it hugely. I live in Balham South West London. I am very close to the A3 which connects with the M25.
I do know my engineer fitted a new pilot assembly in 2016 but presumably it could need replacing once again. My original engineer who worked forTwyford installed the aga 17 years ago ( it was a job independent from Twyford he had a business with another partner) I have tried his contact number over the last few years but think he is no longer in business probably retired! Its very hard to find an aga engineer who works in London and some do not want to deal with converted agas. I would be happy to pay fort travel time for an engineer to visit me if he could sort the problem out. it would save me having to dismantle the kitchen cabinet to get access to the control box every few weeks rather than once a year.
I will definitely get in touch with Sandy if necessary as I would like to get hold of a new ignition lead to replace the one that has sheared off which connects to the sparker this has always worked well.
Best wishes

Hi Nina
The guy I might have suggested lives in Colchester so anywhere beyond NE London is beyond his range.
Speak to sandy (or chris) at oilwarm re your ignition cable and ask if they know anyone in your area .
As far as I know they are now the only supplier of gas conversion kits (and spares for them) so it is likely they will know an experienced guy in every area.
Gas safe register lists a few qualified guys in your area but you would have to quiz them about their experience with converted cookers .
https://www.gassaferegister.co.uk/find- ... Xgd0lxQ%3d

The usual styles are the old Don kits which are now defunct. And Oilwarm (many of the oilwarm spares will fit a Don conversion).
Best to speak to them though

Hi John

I just wanted to update you on my aga woes. Have been on holiday for the past week but thought my experience may be useful for someone else.
My engineer returned and changed the whole pilot light assembly and immediately the flame looked and sounded different. Whether this was necessary as it was replaced 3 years ago I have no idea. and the cost for replacing these items was £72. I am happy to say that a new ignition cable was found and was replaced and sparked well.
In addition the old connector for the thermo couple looked as if it was worn around a place where it had been welded previously This was replaced although my engineer struggled with finding a place to put all the coils of copper wire and tucked it under the control box. I think the old one had been cut down and welded to avoid all the loops as it is much shorter.

The aga appears to be going well for the moment. Thank you once again for help and advice

Certainly sounds like a positive outcome Nina , which is good , not overly expensive , and even if not strictly necessary, is a more positive solution than cleaning the pilot jet which can be a bit hit and miss.
Would be nice if you could keep hold of the old pilot assembly and fit a new jet in readiness for next time . I would bet though that the guy did not leave it . Bit naughty!
