Why does my sprinkler controller have power but no zones run?
Short answer: A problem with the shared control circuit can prevent functioning controller outputs from operating valves in the field — the controller is sending the signal, but the signal is not reaching the valves.
When the display is lit and the schedule looks right but no zone opens, the usual suspect is the common wire — the shared return path every valve depends on. A break, a loose connection, or corrosion at the controller or in a valve box can stop all zones at once, even though each valve and the controller are fine on their own.
It can also be a rain sensor holding the system off, a master valve or pump-start issue, or the water supply being shut off. We test the circuit at the controller first, then work outward, so we find whether the break is at the controller, in the field wiring, or in the water supply.
What we check in Fall Creek
This is a common call in Fall Creek, and it is the kind of problem we test in the yard instead of guessing at from the driveway. We run the system, watch how the water is actually moving, and check the parts that cause this — before anything gets replaced. That is the same approach in the full Smart Controllers service page.

Frequently asked questions
Why would all zones stop at the same time?
All zones share the common wire and the water supply. A failure in either one takes out everything at once, while a failure in a single zone wire only takes out that zone.
Could the rain sensor be stopping it?
Yes — a rain sensor that is stuck, wet, or bypassed the wrong way can hold the system off. We check the sensor setting before we start digging for a wire break.
