It's quite easy to get it to work, just open the oven and look to the bottom left corner and you will see a small screw.you just need an alan key (or pliers) and unscrew. Then replace the battery pack with another, (kodak,energiser or duracell will do.) There is no need to touch the components. Close it try the ignition and hopefully it should work.
