I have a Casablanca Intelitouch Fan that will not turn off or dim the lights using the light swithc. As a result I have to power off the system or run the fan with the lights on. I have replaced the Intelitouch controller and have a 2 wire. The lights worked fine after initial instalition (3 years) but recently the light fuction decided to not work.

If you have already changed the switch it has to be the board in the fan. You can order replacements from Casablanca Fan Repair (http://www.casablancafanrepair.com)
