Why won’t my irrigation valve open?

Test for 24 VAC at the solenoid when the station is on. If voltage is present, the solenoid or diaphragm may be bad; if not, chase wiring, common wire, or controller output. Also open the bleeder screw briefly to see if the valve can operate manually—if manual works but electric does not, focus on solenoid/wiring.
