We have an ignition probe. How near are you talking?
Ignition probe is next to it.. The numbers are 8472
It says in the manual it's an ignition electrode.
It's definitely just the one.
Thank you but I don't think it's that as the other 4 hobs work perfectly fine it just seems to be one individual knob.. Which is the big wok burner. Gas is coming through and it's lighting when you turn and press the knob and ignition but as soon as you let go of the knob the gas goes out.
