What to do if the Rain Bird Control Unit valve won't turn on?

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.
