Spread the love

Sprinkler Timer Troubleshooting – Lawns generally would like lots of water to stay green and lush, particularly throughout the warmer spring and summer months. Sprinkler timers enable you to schedule irrigation periods on multipleSprinkler Timer - in this guide you'll find How to fix your Sprinkler Timer Troubleshooting,SPRINKLERS NOT RUNNING AT ALL,SPRINKLERS COME ON BUT DO NOT TURN OFF,DISPLAY SCREEN PROBLEMS,VALVE WIRING CONNECTIONS,and more... days and within specific time parameters. Along with convenience, timers save water because they can turn it on during optimum, early morning periods, like at 4:30 a.m. However, malfunctioning timers need some basic troubleshooting skills to keep them working correctly.

If a timer isn’t operative properly, the sprinklers might turn on, whereas kids enjoy the lawn or throughout a family get-together. Incorrect programming is the most typical problem affecting sprinkler timers.

A sprinkler timer might not always operate as you programmed it, and it may be frustrating once you can’t understand why. Try to attempt a bit of troubleshooting to see the problem before resorting to replacing the timer altogether.


 

Here is a list of problem and how to fix them

1.Extended Watering Cycles

Some timers can be programmed with more than one start time; each one is referred to as a program and is typically labeled A, B, or C. If the start times overlap, the sprinkler system will run for an extended time. Once the system is activated by start time, every zone can water in order.

If the second start time happens before the first watering cycle is completed, the timer can switch back to the first zone and repeat it. If several begin times overlap, the system may run unceasingly. To correct the problem, clear the start times and reset them to permit enough time for the program to cycle through all the zones.

2. Watering Occurring at Odd Times

If your electricity goes out or your timer gets unplugged or disconnected, the clock or day settings could get skew. Therefore if you discover that your sprinklers aren’t running after you anticipate, examine the display to check if the clock and day are correct.

If not, run through the zone settings to correct the times that the sprinklers ought to run. Attempt temporarily setting the times and days for a time very soon. Therefore, you’ll be able to conduct a fast check to take care of the timer that is currently operating. Once a successful test, you’ll be able to reset the timer to your most well-liked schedule.

3. Watering Cycle Does Not Work

another Sprinkler Timer Troubleshooting appears when A watering cycle won’t begin if a start time and the length of irrigation time aren’t programmed into the sprinkler timer. If the timer is programmed correctly, however, the timer still doesn’t work. It should be defective. To examine the timer, use AN Omni-meter or voltmeter to examine the voltage at the station terminal screws.

Every station terminal controls a zone, activates every zone, and verifies that the corresponding terminal reading is between twenty-four and twenty-eight vac. If the readings are not within the specified range, replace the timer. Some timer models have individual station modules that are replaceable.

4. Programming

Depending on your timer model, a manufacturer default watering setting is usually set once you install the device. Program the timer according to the manufacturer’s directions to accurately water your specific landscape. Leaving the default settings on might waterlog your field or cause drought conditions.

Several models use an adjustment setting to take care of irrigation between extreme weather periods, like hot summer or cold winter. Verify that this adjustment is functioning for your specific season before looking at different potentially malfunctioning parts. Now check if the Sprinkler Timer Troubleshooting has been fixed.


5. Display Screen Problems

The monitor on a sprinkler timer will be blank if it’s not getting any power as a result of it’s not plugged in, the outlet is flawed, or the breaker has been tripped. If the timer contains a backup battery, the screen might show “NO AC” or “NO” to indicate there’s no electric power getting to it.

If the monitor is blank, shows partial letters and numbers, or reverts to the time, whereas the user is programming the timer, the board is also defective. The boards are often broken by moisture within the timer, a lightning strike, a power surge, or a defect within the wiring between the timer and the valves. A timer with a defective board may need to get replaced.

6. Power Source

Each Sprinkler timer includes an entirely different power source, like electrical cords, hard-wiring, and batteries. If you’ve got intermittent power to your timer causing erratic irrigation practices, verify that your cord or hard-wiring isn’t broken or crimped. Electrical cords ought to be plugged into a fanatical circuit, far from different appliances, like refrigerators.

For battery-powered devices, make sure that the battery is correctly positioned within the timer or replaced with a new one. No matter your power source, remove all power from the timer before touching any components to avoid electric shock.

7. Zones Not Being Watered

If you discover that zones don’t seem to be being watered after you expect them to be watered (or at all), check to make sure that your zone settings are correct. Look into the display and run through every individual zone setting.

Occasionally, you’ll discover that zone settings are changed because of a temporary disconnection in electricity or, as a result of it’s been set incorrectly. This can be simple to correct by going through and re-adjusting them to the specified times and days.

Again, you would need to set it temporarily to conduct a quick check before placing it correctly. If you still can’t set the zone settings properly, consult your manual to check if your unit contains a self-diagnostic function. This might not answer. However, the test ought to at least tell you which zone is causing the problem.

8. Valve Wiring Connections

additional Sprinkler Timer Trouble happens when Your timer connects to underground valves that give water to separate sprinkler areas. If your sprinklers aren’t activating correctly, you’re wiring between the timer and valves could also be broken or disconnected.

You need to remove the protective covering from your timer and valve box so you could examine the wiring connections. Every valve typically has two wires: one ground connection and one powered line. All lines ought to be firmly connected to each timer and valves to operate correctly. Replace any wiring that seems worn or crimped.

9. Shorts and Fuses

Valves use solenoids, or wire coils, to harness electric power as they operate hooked-up field sprinklers. If these solenoids malfunction, they usually produce a short within the system’s circuitry. Your timer might show a short within the system and indicate that the valve range is inflicting the problem.

Water in the valve box could cause a Short circuit, or the solenoid itself will malfunction. Resolve the shorting issue to work your timer and system properly. Timers even have internal fuses. Solenoid shorts usually blow fuses, creating the timer inoperable. Check your timer’s fuse box and replace any faulty elements. Fuses defend your timer from severe electrical harm.


10. Sprinklers Not Running at All

For this Sprinkler Timer Troubleshooting, you need to Check for additional easy solutions 1st, as always. As an example, you will often forget that you have turned your sprinklers off due to rain or changed your settings to manual to permit an extra watering cycle.

Kids might also flip and switch without your knowledge. Therefore check even if you know you haven’t changed the settings yourself recently.

Additionally, your timer may blow a fuse if it’s on and set correctly, and your sprinklers still don’t seem to work. Open the timer box and check the fuses for any harm. If they’re blown, replace them, and the problem will be fixed.

The system’s antenna could be the problem as well. This usually takes a 9-volt battery, so if you’ve tried all else and nothing seems to work, pop in a new battery and see if that helps.

11. Sprinklers Come On, But Then Turn Off Right Away

This is usually a case of the runtime being set for a very short duration. This problem can be easily solved by reviewing the duration settings for each zone. Double-check the duration by temporarily setting the run time for a short duration that you can evaluate immediately.

12. Sprinklers Come On But Do Not Turn Off

In this case, the duration time has possibly been set incorrectly for a strangely long period of your time, or the timer is stuck on the manual setting. If the dial is correctly placed within the “Run” position, go through the duration settings and correct them as required.

If neither of those solutions seems to work and the sprinklers keep running, check outside to ensure that the external valve isn’t open. AN open valve would force a lot of extensive corrections that don’t involve the electronic timer.

13. Other Timer Problem

if you still have Trouble with your Sprinkler Timer, check. If more than one valve is opening at a time, the wire from a valve to the timer may be defective.

The electrical current can transfer from the station with the defective wire to the adjoining stations, which will activate the corresponding valves.

Check the electrical wires and replace any that are broken or damaged. A bad fuse in the timer or a defective timer can result in a valve not operating, although the display screen indicates the zone is watering.

Sprinkler Timer Troubleshooting Summary

Friends, I hope you succeeded in fixing the problem with your sprinkler timer. If you did not, check if you have a warranty on the product, call the company for help, or visit the nearest store and speak with an expert.

    Timer comes on and turns off, but when it turns off, the entire system vibrates. We have to go to faucet and turn water off to make vibration stop.

      Hey @Eileen Cassidy
      Vibration is caused by fast-closing. As the water flows through the pipes and the valve shuts off quickly, it causes the water to stop suddenly in the pipes, causing the vibration effect.

    Turned on my system today to check it out, started it on manual on the first zone, and all four zones came on, when I changed zones all four ran again, my timer showed no errors, it looked normal. Messed with it trying different things, no luck.
