Sorry for the late response, the last few days have been too hectic with the trade show for me to get online. Please send in the controller. It is very rare for a wavebox controller to fail and in a canopy, condensation could be a problem. If there is no evidence of water damage and it is less than 2 years old it will be replaced under warranty. I get back to the office on the 24th.
