I've got a Truma S3002 p gas fire. I haven't used it in a long time and when I went to light it, it sparks up fine, but when I release the knob after lighting the pilot, the fire itself doesn't fire up. People have suggested I've not held it long enough but I've stood for 5 full minutes with the knob pressed in and the pilot lit, and it goes off instantly when I let go. Any suggestions as to what may be wrong with it?

thermocouple i reckon- in case you don't know it's the failsafe that is like a little torpedo sticking into the flame. it holds the gas valve open as long as the flame is on it,and if the flame goes out, shuts the gas off. they do fail,and they won't let the valve stay open

Hi Brown, thanks for this. Is it easy to open up the fire to get at this do you know?

Yes I'd agree with thermocouple.
On the Smev hobs a similar arrangement applies. On these I find the thermocouple earth can become loose/faulty. This increases the resistance, and means it takes a hotter flame to get it to stay on, or it won't stay on at all. So, worth checking the connections to the thermocouple to make sure they are clean and tight. That may solve it.

It's almost 11 years old so if that's what the problem is it may be worth replacing anyway? Depends how much work is involved in getting at it I suppose.
