A while back, I bought a fan controller. It was a Spire Digipanel. I couldn't find anywhere on the maximum amps it allows for a fan. Anyway, I hooked up my Delta to it. When I set the speed to maximum, the fan was running at the max speed so I thought it would be able to handle it. Now, 6 month later, the fan won't start on the controller. The other 2 fans that are hooked to it are still running fine. Could something have gotten burnt out?
