It all depends. Mine did the same thing. You can go the route that I did with our 14 yr old which was to triple check every connection on it then replace the ignitor and end at the conclusion that the card was bad. At that point figuring it would be about $125 to repair it or buy a new one on Ebay for $350 I went with a new one.
We travel for 7 months so there is a value in updating the appliances and not worrying about them. AC acted up so I replaced it for $575. It's noticeably more efficient, starts easy and quieter.
Doesn't cost anything but your time to check everything over.
