Smev Oven Going Ou (1 Viewer)

[2GB Racing]

Hi all any thoughts as to why a five year old hardly used Smev grill / oven will not stay alight ?
It ignites straight away, Flame increases with the control knob but within minutes goes out !
I have recently installed an lpg underslung tank, Trauma filter etc, everything else is working just fine ?

leave the door open for a few minutes untill it gets going properly

Check your thermocouple is OK

ok will try leaving the door open longer, not sure re thermocoupling no experience of gas cookers please advise ?

Make sure there's a reliable flame playing onto the safety thermocouple. It must be kept hot to open the gas valve.

Sounds like the thermocouple to me also.
The thermocouple is the flame failure device, the tip of it is in the flame and all the time it is heated it keeps the gas valve open.

Most MH cookers have thermocouples fitted which shut the gas off if the flame goes out, you would normally hold the knob in to maintain gas flow until the thermocouple gets to the correct heat, if the oven stays lit whilst holding the knob in and then goes out very shortly after you release the knob it may be a faulty thermocouple, try holding the knob in longer than usual before releasing it as if it stays lit until you release it then this will highlight the problem for you

If you look at the gas ring on your hob you will see two extra bits sticking up at the side of the ring. One is the igniter and the other is the thermocouple. Hopefully that explains what you are looking for. These often just need to be bent (gently) into the flames.

Is it definitely going out, ours was doing the same after 10 to 15 mins although a top gas expert said it is not going out but has reached temperature so the flame goes down. We still think it's going out hard to check can't see a flame at all but he said there is one but it's very low because it's reached temperature.

What number is the knob on, the highest one?

with the oven off, remove the shelf and stick your head inside. Down the bottom at the back you will see the burner and a long cylindrical thermocouple on a brass pipe. This is held into the flame by a small bracket and sometimes they get dislodged

Thank you all for the informative suggestions I have tweaked the thermocoupling location by a few thou and yipee kitchen calm was restored as the oven stayed slight for the duration required

A useful qualification of the instruction there

Good to know the thermocouple solution worked, will put this one in my hints and tips file
