Why does my sprinkler system run at the wrong times?
If your system runs at unexpected times, the controller is almost always the cause — either due to programming conflicts, electrical issues, or faulty rain sensors.
Common Causes
Your system may run incorrectly because of:
- Overlapping start times
- Multiple schedules active at once
- Power loss resetting the controller
- Faulty wires
- Stuck relays
- Broken rain or freeze sensors
- Old controllers losing memory
Even one incorrect setting can make the system run at night, midday, or multiple times per day.
