What happens if a fuse blows in a sprinkler system?
A blown fuse inside the sprinkler controller is one indicator that something has gone awry. It is simple enough to replace the fuse, but the underlying cause must be determined to keep it from blowing again. A sprinkler system does not function at all if the fuse blows.
Why does my Fuse keep blowing when I plug in?
The other 10% of the time this fuse blowing problem is caused from a bad ribbon (the wire bunch that connects the digital fact to the circuit board), a faulty circuit breaker, or even possibly a short in your multi-strand wire. But, more times than not, it is just the solenoid.
Why won't my sprinkler system turn on?
If it's the right breaker then there may be a wiring problem, a low voltage problem, or a pump or pump start/run capacitor problem. Ok Checked the amp requirements. Label says it needs 12.6 amps with a high of 16 amp usage. It is a 10 amp Square D breaker. Also should say that if we turn the sprinklers on manually it works fine.
What happens if the sprinkler control box blows?
The control box may still have electrical power, but the valves will not open or close. This means the sprinklers will not run and there is a risk that the soil will dry out and plants will suffer. If it blows while part of the landscape is being watered, that valve will remain open and the sprinklers will continue to run until shut off manually.
Why does my Fuze keep blowing?
Overloaded Circuit The most common cause of a blown fuse is when something draws too much power from the circuit. This is most often caused by either too many lights or from using too many plug-in appliances at once. The biggest culprit for this kind of issue is a multiple outlet adapter plugged into a socket.

What causes a sprinkler fault?
When the sprinkler zones do not turn on at all, it is generally a problem with the electrical signals running from the controller to the valve solenoids. More rarely, it is caused by a faulty valve that needs to be rebuilt or replaced.
How long do sprinkler controllers last?
In general, they should last a good 40 years as long as they are protected from direct sunlight, which can damage them. Wires, however, must be replaced regularly as they can rust over time. You should also expect to replace your controllers every five to 10 years.
Where is the sprinkler solenoid located?
In newer lawn irrigation systems, the valves should be installed in valve boxes set into the earth. Often these are easily visible. In small yards, there is often a single valve box located near where the irrigation pipes enter the ground from the water source.
How do you change a fuse in a sprinkler system?
Fuse Replacement Unplug the sprinkler controller from its power source. Pull the blown fuse out of the clips that hold it by hand -- do not attempt to use pliers, since the glass could break. Some controllers come with a spare fuse taped to the inside of the panel door that can be used as a replacement.
How do I change a sprinkler fuse?
Remove the fuse by grasping it between the thumb and index finger and pulling until it comes free. Inspect it visually to see if the tiny metal filament inside the glass tube is intact or broken and replace the fuse if necessary. There is often a spare fuse taped to the inside of the controller box which can be used.
Why is my sprinkler timer not working?
This is almost always a problem with your timing system. Check your timing program and make sure that your duration settings are properly configured. When you make an adjustment, run a test by setting up a temporary program to turn on within a minute or two and check how long the sprinklers stay on for.
Why won't my sprinkler system turn on manually?
Here are some common reasons why your sprinkler system won't turn on: Lawn sprinkler control timer isn't working correctly. Clogged or dirty sprinkler heads. Broken sprinkler heads.
Does each sprinkler zone have a solenoid?
Related Articles. Sprinkler systems have valve controls for an area, or zone. Sprinkler valves have an electrical solenoid on top that receives a signal from the controller as to the time and duration of an irrigation schedule.
Should there be water in my sprinkler valve box?
Why is my irrigation valve box full of water? An irrigation valve box can hold water after a heavy rain or when a valve, pipe or fitting is leaking. If the valve box is always full of water and you have ruled out irrigation leaks, check to make sure your French drain pipe isn't clogged, if you have one.
How to tell if a sprinkler valve is failing?
The valve is green or black, maybe faded, with a hexagon sticking out of the top (solenoid). There will be waterproof wire-nuts or splices in there. These may be wrapped in tape, but inside, it should be grease-filled clips or wire nuts. If it’s not grease filled, that may be your whole issue, with corroded wires, etc. All of the valves will splice the black wire, but only one will splice the wire you identified before (Yellow for me).
How to test if sprinklers are turning on?
Next, test that it turns on manually by twisting the solenoid counter-cockwise about 1/8th turn. The sprinklers should come on. Twist it back to shut them off.
How to drain a sprinkler pipe?
If you wanted to drain the pipe, you can open a valve by twisting the solenoid counterclockwise 1/8th of a turn. That will let the pressure out of the pipe and it will drizzle into whatever sprinklers are there. If the valve is at the low spot, you’ll still have water come out when you pull the valve. That’s fine, because it will help flush some of the debris out of the valve (if any).
What happens if you pull a low spot valve?
If the valve is at the low spot, you’ll still have water come out when you pull the valve. That’s fine, because it will help flush some of the debris out of the valve (if any). Remove the clips/wire nuts, and push the wires aside. You don’t need to pay attention to polarity.
How many volts does a power brick need to be to replace a valve?
There should just be an “off” position, but you can unplug the power brick too if you want. It’s only 24 volts, but it’s AC, and the box will have water in it. This makes it a little bit of a hazard, at least from a comfort issue, if it were to turn on.
Why does my fuse blow?
The other 10% of the time this fuse blowing problem is caused from a bad ribbon (the wire bunch that connects the digital fact to the circuit board), a faulty circuit breaker, or even possibly a short in your multi-strand wire. But, more times than not, it is just the solenoid.
What happens when a sprinkler system advances to a certain zone?
Your lawn sprinkler system is working just fine and then when it advances to a certain zone, it automatically pops the 1.5 amp fuse inside the clock and power is lost. You replace the fuse and advance your clock to the zone it was on...And it does it again!
Does Rainbird have a fuse?
Rainbird has since improved the design of the ESP model timers and built an internal fuse which does not blow. The clock senses the bad solenoid or short and automatically skips over this zone until you have fixed the problem and reset the clock. This has saved a lot of headaches for many homeowners and irrigation contractors!
What happens if a sprinkler blows a fuse?

Why does my controller fuse blow?
Underlying Causes. A faulty solenoid is the most common cause for a blown fuse. If the fuse blows again when a particular valve is turned on by the controller, try replacing the solenoid on that valve. It is also possible that a short has occurred in the wiring between the valves and the controller.
Why won't my sprinkler system work?
A sprinkler system does not function at all if the fuse blows. Most controllers will have a message in the display indicating that the fuse has blown. The control box may still have electrical power, but the valves will not open or close. This means the sprinklers will not run and there is a risk that the soil will dry out and plants will suffer. If it blows while part of the landscape is being watered, that valve will remain open and the sprinklers will continue to run until shut off manually.

Why do kitchens have GFCI outlets?
The danger of shock increases when a person is in direct contact with the weak path to the ground. That’s why kitchens and bathrooms usually are equipped with GFCI ( ground fault circuit interrupter) outlets. The Fix: This is essentially the same as the fix for a short circuit.
Why is my circuit breaker cutting off?
If so, the circuit breakers are doing what they were meant to do: cutting off the flow of electricity because of some type of surge (fault) or other problem. The Fix: Before resetting the breaker, check for any indications of damage. If the breaker trips again, there could be a problem.
What causes a short circuit?
Cause 2: A Short Circuit. A short circuit is a type of electrical fault. Faults, in general, occur when an electrical current strays beyond its intended path (circuit) due to a lack of resistance (e.g., from insulation or a circuit breaker).

Why does my pump make a buzzing sound?
A usually quiet pump starts buzzing while in operation: When the pump starts buzzing, it means the relay is on the fritz, and it needs to be replaced. Since the relay is a magnetically activated switch, its contact points start to oxidize, making it ineffective at pulling together the high voltage contacts. The result is a buzzing sound. High moisture or high salt climates will accelerate this process resulting in shorter service life.
What happens if a valve is not installed?
If the valve is not installed at the highest point of the system, there may be backflow entering the valve after shut down. If backflow enters the valve, it will cause the disc to skip as it is pushed against the backflow. The result: water will come in through the inlet during start up.
How to fix a pump that pops up and down?
To fix this problem, move the indexing valve closer to the water source, so that the electric control valve or pump is closer to the indexing valve to pressurize the supply line.
Why does my water pump trip the breaker?
Andrea#N#I can't say with just the information in your text but common reasons for a water pump or any electric motor to trip a breaker is that the motor is drawing excessive electrical current; In turn that's often caused by a failing electrical motor.
Why does my breaker keep tripping?
If a breaker keeps tripping there is most likely an intermittent short in your wiring or an overcurrent caused by a failing pump motor.
What does it mean when a pump sounds like it's shorted?
Sounds like a shorted wire or an electrical failure or short in the pump itself. Double check that the wiring connections are correct.#N#WATCH OUT: there are hazards of death by electrocution - if you're not trained you could be killed.
How to check if a pump pressure switch is tripped?
Start at the pump switch: assure that power is on ; check the main panel for a tripped breaker or fuse; if power is on and no fuse is tripped then check the pump pressure switch itself: some pump pressure control switches include a pump protection circuit that shut the pump off if it is running too long or seems to be running dry (which can ruin the pump motor).
What causes a water pump to draw high current?
Most likely the water Pump or its control or wiring is shorted or motor is failing and drawing high current.
What is a pressure switch in a well?
