Hi - when I light the oven on my Plastimo Atlantic Oven it lights fine but even on full gas the flame never bursts into life. I'm presuming that's what should happen? It just stays at that low initial level.

Gas bottle is brand new.

And it's def a weekend for some hot food....

Any ideas please?

Thanks, Jonny
 
Does it get up to temperature OK ? If it does the thermostat should reduce the flame height accordingly, if not possible faulty thermostat.
 
HAD THE SAME PROBLEM ON OUR COOKER. tOOK THE BURNERS TO BITS, CLEANED OUT THE HOLE WITH SOFTISH FUSE WIRE / DRESSMAKING PIN. WORKED FINE THEREAFTER.

FOR SOME REASON THE HOLES FUR UP.

SORRY ABOUT THE CAPS - TOO LAZY TO RE-TYPE!
 
Great thanks, can you just lift the burners out with the cooker in situ?

(the low level flame you get when you first light the burner just remains - it never clicks into "action" - so no the temperature never gets up)

Thanks,
J
 
It maybe down to bad assembly.
We had the same problem and the corgi chap said something about too much sealant on the thread being squeezed into the gas aperture when the joint was tightened up. Once cleaned and re-assembled, all was well.
 
Assuming all the other burners are OK and can all be used at once (thus eliminating any problems with the supply) I would supect the thermosat but I would check the jet in the oven burner first.
 
Yeap checked the oven burner - seems fine. Think it must be the thermostat. That's the small rod that sits over the flame in the middle? Is that possible to replace? Do you just replace the part over the flame - or the whole thing from there back to the control knob?

Thanks for your help

[/ QUOTE ] That sounds like the sensor for the flame failure device, at least if it's in the flame. They call it the "thermocouple". I think if that had failed the gas would simply not stay alight at all. (It is all one unit right back to the control and costs £10.) It must be difficult to get it to stay alight initially anyway if you've only got a very small flame. I'd looking for something in the top of the oven but michael-w now casts doubt on the diagnosis. I think he is wrong because Calormarine show a complete upgrade kit (actually NLA) that consists of 2 new hot plate burners, grill and oven thermostat.

Have you been able to check the actual gas jet in the burner though. It'll have a very small hole in it. Complete new burners are £23.

You do have gas in the bottle and the isolating valve fully is open and you can get both hob burners on with the grill all working normally.

With all due respect I think if you don't know what you are looking at or how it all works maybe you should not be trying to repair it yourself.

Replacing a thermocouple is no problem as it does not involve actually messing with any gas connections. The thermostat is very probably going to involve the whole control being replaced and that'll mean connections on the gas itself.
 
Careful. That small rod is likely to be the flame failure device, intended to turn off the gas if the flame is blown out. If there is a thermostat then it should be detecting the oven temperature, not tne flame.
 
Re: Small rod in middle

I am just in the throes of replacing my 1987 Atlantic - because I have been advised there is no thermostat in the oven and no flame failure devices on the hob burners. Oh, and there are no spares made anymore to do an upgrade.

Very happy to be proved wrong as we are rather fond of it!

[/ QUOTE ] You are right i guess, that's why the upgrade kit on the Calormarine website is stated to be no longer available.

However its previous existence must have been because the Altantic did not in fact have flame failure devices on the hob and grill or an oven thermostat (Ugh no oven thermostat, OK if you don't want to cook anything.)

Back to looking the burner to solve the problem unless the bit about the control being counter intuitive is the answer. Normal anyway, the hob burners would be the same wouldn't they. Ours at home are and so are those on my cooker on my boat.

Our Atlantic has thermostat

[/ QUOTE ] Looked in an old catalogue (2000) It is decribed there as having an oven flame failure device but is "controlled by a 4 position valve to aid temperature control"

Seems some do and some dont, depends on age and if upgraded i guess.

I reckon for twinrudders its back to suspect the thermostat if it has one but check the gas jet in the burner first.
 
Thanks for your help - so it seems there is no thermostat - only a flame failure device (Thermocouple)

It lights easily as soon as you press and turn the knob - it's just that at full volume (think that's the 12 0clock position from memory ) the flame is lit across the burner but only about 1cm high - I can reduce it a bit etc. Oven just doesnt get hot. The burners work and the grill - and the gas bottle was brand new as they left us none.

I took the oven out - took the back off - and removed the burner - gave it a clean - and a sort of air ministry test no 2 and blew through it - all seem fine. Put back - and exactly the same problem. I doubt a new burner (£26) would make any difference.

What I didn't do was look at the actual jet that bows the gas into the burner. Worth taking that off as well and having a look at that do you think..??

Failing that - have to either get someone in or get a new cooker which seems a bit drastic (and expensive)

Funny thing is although the boat (which I have just bought) is 1991/2 vintage - the oven looks unused - apart from some breadcrumbs...I just wonder if the previous owners just used it to warm some bread and never got round to fixing it...

And all because the surveyor refused to test the gas system because the pipes were out of date and it didnt have a secondary gas isolator switch inside the boat near the oven (just has the tap on the bottle itself to kill the supply)

[/ QUOTE ] Yes , for the third time check the jet!
 
There are 2 probable causes for reduced rate if all other burners are ok. Check the oven burner it is an ideal home for spiders which nest there over winter -daft but more common than you would believe. Oterwise the oven jet which can be accessed whilst the oven burner is out - use fuse wire to clean the jet and blow a VERY small amount of gas thru the pipes whilst jet is out. If this does nt work you need a fitter or contact manufacturers.
