The 'ignition system' ie the push button arrangement on my Rangemaster 55 single oven gas cooker, no longer ignites the gas when it is pushed and I have resorted to an independent battery operated igniter.
I am uncertain about whether this is something I can easily repair/replace and would appreciate your guidance. Also, if the 'problem' I am describing is obvious to an expert and I need to purchase a replacement part, what do I need, can you supply it and how much will it cost?
