Used Viking range: Igniters aren't working

I have found a nice looking viking range for sale, very cheap. The seller says that the igniters are not working. He lives far enough away that I would like to know as much as possible before going to see the item. It is my understanding that there are no electronics in Viking ranges. Does this mean that if the 'igniters' are not working, then changing the spark module will fix it? Is it as simple as that? Or is there anything else it could be? How much could repairs cost max? Is this a potential can-of-worms? The price is cheap enough that even a modest repair would make it worth it. Can anyone provide any help or insight? Thanks alot.
