I have a gas hob where three of the gas igniters work but the fourth doesn't. Does anyone know how you can get this replaced ? is it cheap to do? is it a majo r job? alternatively can you still getthoe mnaual gas igniters where i turn the gas on on the hob and use it to ignite the flame?
Have you tried dismantling the components of the ring and making sure everything is clean? One of mine wouldn't saprk and it was due to dirt on the tip not allowing a spark to jump.
Yes, we had an identical problem with our low simmer hob and after dismantling it and giving it a through clean and degreasing it now works a treat. I suspect that over a period of time, even when the hob surface is wiped over, a layer of grease builds up which slowly clogs everything up.
