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 multiple days and within specific time parameters. Along with convenience, timers save water as a result of they can turn on during optimum, early morning periods, like at 4:30 a.m. However, malfunctioning timers need some basic troubleshooting skills to stay them working properly.
If a timer isn’t operative properly, the sprinklers might turn on whereas kids are enjoying on 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 the troubleshooting to see what the problem is 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 period of time. Once the system is activated by a 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 the cycle. 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 actually 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 the timer 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 also the length of irrigation time aren’t programmed into the sprinkler timer. If the timer is programmed properly, 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; activate every zone and verify that the reading of the corresponding terminal 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.
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 water log 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 is going to 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 back 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 also the valves. A timer with a defective board can need to get replaced.
6. Power Source
Each Sprinkler timer includes a completely 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 replace it with a new one. No matter your power source, take away 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 certain that your zone settings are literally 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 possibly set it temporarily to conduct a short check before setting it properly. 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 give an answer, however, the test ought to at least tell you which of the zone is causing the problem.
8. Valve Wiring Connections
additional Sprinkler Timer Troubleshooting happens when Your timer connects to underground valves that give water to separate sprinkler areas., If your sprinklers aren’t activating properly 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 normally has 2 wires: one ground connection and one powered line. All lines ought to be firmly connected to each the timer and valves to properly operate. 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 brief within the system’s circuitry. In fact, your timer might show a brief within the system and indicate that valve range is inflicting the problem.
Water in the valve box could cause 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 simply have turned your sprinklers off as a result of rain or changed your settings to manual in order to permit an extra watering cycle.
Kids might also flip dials and switches without your knowledge, therefore check even if you know you haven’t changed the settings yourself recently.
It is additionally potential that your timer may need blown a fuse if it’s on and set properly and your sprinklers still don’t seem to work. Open the timer box and check the fuses for any harm. If they’re so blown, simply 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 possible been set incorrectly for a strangely long period of your time or the timer is stuck on the manual setting. If the dial is properly placed within the “Run” position, go through the duration settings and correct them as required.
If neither of those solutions seems to work and therefore the sprinklers keep running, check outside to make certain that AN 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 Sprinkler Timer Troubleshooting, 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.
I hope that you succeeded to solve your sprinkler timer troubleshooting, with the article.
