@pigletjohn can you help ? Rented house, Montpellier gas oven, when I turn the control and press the ignition it does light, but as soon as I let go it goes out. The grill will light and stay lit. Oven was professionally cleaned about three months ago due to previous tenant leaving it filthy, so it shouldn't be that causing the issue. Any ideas to why this is happening, the oven was replaced two years ago so not particularly old.
