The solenoid lends itself to repair just like any other component, and savings can be realized by doing so.

If you’re asking about the electronic pressure control solenoid, it’s on the driver side of the valve body. There are 4 sols on that side, it’s the one closest to the rear.

Place the metal blade of an insulated screwdriver across both metal contacts. This bypasses the solenoid and creates a direct connection between the starter motor and the ignition switch.

1. Place the vehicle in neutral or park with the emergency brake set.
2. Slide under the vehicle and remove the main starter wire and the two (or three) ignition wires on the back of the solenoid.

It can be an under or over-voltage, wrong valve capacity, impurities in the media, pressure drop, wrong material, or just bad installation. To diagnose a malfunctioning solenoid valve, here are the common faults or problems to look out for.

Often, the malfunction of a solenoid valve can be attributed to easy to fix issues, such as dirt in the valve (80% of the cases). Another common issue is a too low differential pressure for indirect operated solenoid valves.

Solenoid Valve fails to open. Check if valve is normally closed (power to open) Or Normally Open (Power to close) Use magnetic detector lift coil slightly to check if magnetic field is present.Do not remove coil if energised as IT WILL BURN OUT Check contacts Check wire connections and DIN connector. Check fuses.

Wear and tear to the wire or slug can also cause the solenoid to become stuck. A gentle tap on the casing is enough to dislodge the metal slug so that the solenoid can work properly. Reassemble your electronic device, following manufacturer’s instructions for the specific piece of equipment.

It is expected to last about a year. The lifespan of valves that have to work harder is 1-2 years. Users can prolong the valve’s lifespan through regular maintenance.

solenoid cleaning helps solenoid performance I usually take out the plunger and scrub it with alcohol on a rag. Then I put the alcohol soaked rag on the end of a screwdriver, stuff it into the solenoid base and twist.

The solenoid becomes too weak to close, so it receives a continuous high inrush current and burns out. In rare cases, a solenoid coil will burn out due to over voltage. Excessive force can be caused by overvoltage or by a reduced load on the solenoid and must be absorbed when the plunger hits the C-stack or field.

Solenoid valves may not open because of power failure, uneven pressure, wrong voltage, dirt under the diaphragm, corrosion, missing components, or a burnt coil. However, since there are so many causes, you must try to narrow down the problem in order to fix it.

How to Troubleshoot the Solenoid Valve on Rainbird Automatic Sprinklers

1. Locate the solenoid on the water valve.
2. Unscrew the plunger from the valve by turning the solenoid counterclockwise.
3. Remove any dirt or debris from inside the plunger well.
4. Remove the wires from the solenoid unit by pulling on the connectors.
