10 y/o indesit cooker k344g/g; 3 y ago changed thermocouple as pilot would not stay on when knob released. worked fine until few weeks ago. now once oven reaches temperature and quietly slows down and the burner stops the pilot flame remains for a few minutes, the I hear a click and I know the pilot's gone off. is it the thermocouple again?
