  If the valve on your Rain Bird Control Unit isn't turning on, there could be a few reasons. First, check for power between the controller and valves by using the 'Manual Start' button and a voltmeter. If there's no 24-30 volt reading, the issue is likely with the controller or wiring. Look for shorts or breaks in the wiring. Alternatively, the solenoid might be burned out or clogged. If the wiring is fine, try swapping the solenoid with one from a working valve to see if that fixes the problem. If it does, replace the solenoid.

  To troubleshoot a Rain Bird Control Unit valve that won't turn on, start by checking the power between the controller and valves. Use the 'Manual Start' button and a voltmeter to check for a 24-30 volt reading at the common and station terminals. If there's no reading, inspect the controller and wiring for shorts or breaks. Also, check the solenoid. If it doesn't 'click' when activated, it may be faulty. Try swapping it with a working solenoid to see if that resolves the issue.

  Your Rain Bird Control Unit valve might not turn on due to a lack of power between the controller and the valves, or because of a faulty solenoid. Check the power by using the 'Manual Start' button on the controller and a voltmeter to see if you're getting a 24-30 volt reading. Also, the solenoid should make a distinct 'click' when activated. If it doesn't, it may be burned out or clogged.
