When every other sprinkler zone fires on schedule but one stays dead, the problem is isolated to that zone's valve, wiring, or solenoid — not the controller or water supply. A stuck diaphragm, severed low-voltage wire, burnt solenoid coil, or a debris-clogged valve are the usual culprits. A landscaper or irrigation technician traces the circuit from the controller to the valve box, tests solenoid resistance with a multimeter, inspects the diaphragm for tears or mineral buildup, and either repairs or replaces the faulty component to restore full coverage.
