Faulty wiring is a frequent cause of inactive irrigation zones. Damaged or loose wires can break the connection between the controller and the valves. Inspect the wiring for visible damage, such as cuts or frayed ends. Use a multimeter to check for electrical continuity across the wires.
Ensure all wires are securely attached to the controller terminals. Tighten loose connections and replace damaged wires with new ones. Incorrect wiring can also prevent zones from activating. Verify the wiring matches the manufacturer’s guidelines in the Hunter controller manual.
Valve Or Solenoid Issues
The valve or solenoid controls water flow to each irrigation zone. A faulty solenoid can block the activation process. Check the solenoid for dirt, corrosion, or physical damage. Clean it thoroughly and replace it if necessary.
Inspect the valve for clogs or mechanical faults. Debris inside the valve can restrict water flow. Disassemble the valve and remove any obstructions. Test the valve after cleaning to ensure proper operation.
Ensure the solenoid receives adequate electrical power. Use a multimeter to measure voltage at the solenoid terminals. If no power is detected, check the controller wiring or replace the solenoid.
Incorrect Watering Schedule
Dealing with an incorrect watering schedule on your Hunter controller can be frustrating. Maybe your lawn is turning into a swamp, or worse, your plants are drying up under the scorching sun. The good news is, most of these issues come down to simple settings that can be fixed in minutes. Let’s break it down step by step to get your schedule back on track.
Resetting The Schedule
If your watering schedule seems completely off, resetting it might be the easiest solution. Start by locating the “Reset” button on your Hunter controller. Most models have a clear reset option—check your manual to be sure.
Hold the reset button for a few seconds until the screen clears or flashes. Once the reset is complete, re-enter your desired watering days, times, and durations. This clears out any accidental settings or glitches that might be causing the confusion.
Be intentional when setting up the new schedule. Think about your plants’ needs, weather patterns, and local watering restrictions. A thoughtful schedule can save you water and keep your plants healthy.
Am/pm And Day Settings Errors
A common mistake is mixing up AM and PM on your controller. For example, you might set a start time for 7:00, thinking it’s in the morning, but the system reads it as 7:00 PM. This can completely throw off your watering routine.
Double-check your time settings. Look for a small AM or PM indicator next to the time. If you’re unsure, consider setting a test run to confirm that the watering happens when you expect it to.
Day settings can also trip you up. You might accidentally choose “odd days” when you meant “even days” or select the wrong day of the week. Review your calendar alongside your controller to ensure everything matches up. Small adjustments here can make a big difference in how your yard looks.

Rain Sensor Malfunctions
Rain sensors are essential for efficient irrigation. They prevent overwatering during or after rainfall, saving water and protecting your plants. However, when your rain sensor malfunctions, it can disrupt your irrigation schedule and potentially harm your lawn or garden.
Understanding how to troubleshoot common rain sensor issues can save you time and frustration. Let’s break it down into manageable steps.
Bypass Switch Troubleshooting
The bypass switch allows you to temporarily disable the rain sensor. If your irrigation system is running during rain, the bypass switch might be set to “ON.” Check the switch on your Hunter controller. It’s usually labeled as “Sensor Bypass” or “Rain Sensor.”
Set it to “OFF” to ensure the sensor is active. If the irrigation system still operates during rain, the issue might lie with the sensor or wiring. Inspect the connection between the controller and the rain sensor to ensure it’s secure and free of damage.
Sensor Placement And Cleaning
Rain sensors can’t function properly if they’re in the wrong spot. Ensure your sensor is mounted in an open area where it can detect rainfall directly. Avoid placing it under trees, roof overhangs, or any structure that blocks rain.
Dirt and debris can also interfere with the sensor. Regularly clean the sensor disks or vents using a soft cloth and a small brush. A clogged sensor might think it’s dry even during rainfall, causing your irrigation system to run unnecessarily.
Still having trouble? Consider testing the sensor by pouring water over it to see if it triggers the controller. If not, it might be time for a replacement.
