Jandy Lxi heater error solved

Just joined TFP because you guys rock!
My Jandy Lxi power distribution card got wet and burnt up. I replaced the card and then got a single flash error, air flow fault, on the ignition control box. I was just getting ready to run through the jandy troubleshooting flow chart, which looked pretty complicated, and seems to mostly tell people to replace their blower, or call a service guy, when I found an old TFP post. Someone suggested jumping F1 and F2 and if the blower starts, replacing the ICB. Well, the blower started when jumped. So I replaced the ICB and the heater stared right up!
Just wanted to say thanks to TFP and revisit this solution for anybody else in this situation.
