I am the proud purchaser of three Rachio controllers. My first, a Gen 2 controller, has been installed at my church for years and works flawlessly. I recently purchased a 16 zone Gen 3 for my own backyard and it works great.
I just purchased a 16 zone controller for my front and side yard. I admit it, I took a chance and bought it off eBay. Everything looked good in the posting but it was dead on arrival and I hope it is fixable.
The power supply is good. It works with my backyard 16 zone controller. When I plug the working power supply into the controller nothing happens … no lights.
After looking closely at the pcb I found no melted parts but I did find smudges near two parts. Please see the picture. At the back end of the power supply connector there is a smudge and, nearby, there is a smudge next to a capacitor. Before taking the pictures I wiped a bit of that smudge off with my fingernail.
If you think that I am on the right track to fixing my problem, please help me determine what parts I need to order.
Thanks for your help.
