Question
I am receiving an "FUSE 7 16" error on my Richdel Controller (Model 446PR). The error occurs when the controller is not even set to water using my settings. This is a six zone timer. If I run each zone on manual, they all run fine. When I do set the controller to run in the early morning it may/may not water the each zone, very sporadic.

Answer
Hey William, it is time to replace this controller. The circuit board is starting to go bad, and it is not worth it to try to repair it. I would suggest replacing it with either a Rainbird "ESP" series controller or a Irri-trol "Rain Dial" series controller. Good luck and have a great day.
