RainDial display blinks OFF or flashes
If you try to turn on a valve manually (by selecting a valve, adding minutes with the + button) and the LCD just goes back to OFF, it’s typically one of two things.
(Note, this problem usually means the controller needs repairing, we’d appreciate your business if the following troubleshooting information suggests the controller needs repairing. Thanks!)
- The controller is overloaded with a shorted valve or wiring problem.
- Some older systems don’t have or show a Fuse error message, so follow the instructions the Fuse: Link
- Valve problems causing this problem are easily solved by replacing the valve solenoid. They’re fairly easy to replace. I usually take a photo of the valve to a local landscape store so they know what I”m looking for. Read the troubleshooting tip below.
- If the problem happens with more than one valve; it means the controller is failing. This is a problem we repair frequently (the cornerstone of our business); the repair is solid and well worth doing.
Troubleshooting tip: Is the valve a problem or the controller?
A good way to tell the difference is if the problem occurs with more than one valve. If more than one valve shows the problem then it’s a problem with the controller. If only one sprinkler valve exhibits the problem, try swapping the screw terminal wire of that valve with a different one. If the “problem” follows the valve, it’s a valve issue.
