Oven Won't Stay Lit

[sstan]

I have a Smev range in my truck camper. It uses piezo spark ignition for the burners and oven. I'm having a problem now with the oven staying lit. It lights fine when holding the knob in but goes out as soon as I release it. I just tried installing a new thermocouple but the problem remains.

Any ideas?

Thanks, Steve

That is the condition of a bad thermocouple.
It is not unheard of to have a new one that does not work as well
