If your retic is not working it will be for one of these reasons below
Control box is not putting power out of the station terminals. If you turn your controller on and it looks like it is working yet there is no water coming out of the sprinklers. You can measure the voltage coming out using a multimeter if there is no voltage then your controller or transformer has failed and will need to be replaced.
If your controller has a plug on it you can do it yourself if it is hard wired to the power supply then is must be done by a registered electrician.
TLC are registered to install controllers and for this we charge from $365 to supply ,fit and set a 6 station controller
If you are getting 24 volts from the terminals then the controller is working and the issue will be one of the next 2 items
Master solenoid valve has failed
To test this you can turn your valve on via the manual switch then turn on your controller if you get water when the controller is on then you know there is an issue with the valve. While the controller is on you can measure the voltage at the master solenoid valve using your multimeter it should read 24 volts if it does then you need to replace your master solenoid valve if it reads below 24 volts then you have a break in your master solenoid wire. You will need to locate and repair the break in the wire or rewire back to the controller or if you have a station solenoid valve nearby you can use the wire to this with a adder station to make the valve work
broken common wire
the common wire goes to every valve in the retic system so if this is broken then one or more of your stations will not work
