Hello, I sent an email a couple weeks ago about this and never received a reply. I have a coralbox return pump that stopped functioning out of the blue. It tries to run for a few seconds, then the lights on the controller flash on and off and the pump stops. After a few seconds this process repeats. I took the pump apart and deep cleaned it thinking some fouling was preventing it from running, but it didn't solve the issue. Could the controller have died, and if so do you sell replacement controllers? I attached a video of the controller flashing and turning off.
Thank you for your help.
