Some of the links on this forum allow SMF, at no cost to you, to earn a small commission when you click through and make a purchase. Let me know if you have any questions about this.
I'd consider calling Bradley on that. Their number is (800) 665-4188 and they're typically pretty helpful. I searched a bit on one of the Bradley sites and it looks like this could be an issue with the smoke generator timer. If they won't send you out replacement part under warrenty, see if they can give you a part number. From there, you could contact yardandpool.com. I've purchased parts and supplies from them in the past with good luck.
