Zone 6 Works Manually But Not from Controller: Electrical Fault

Single Zone Fails Only on Automatic: Wiring or Solenoid

8-zone system. Zone 6 added last year, worked till winter. Now all zones work except 6. Valve has on/off knob (manual bleed). Turns on manually. Controller doesn't activate it.

Manual Bleed ≠ Automatic Operation

The knob is a manual bleed—it opens the valve hydraulically, bypassing the solenoid.

Electrical Troubleshooting

Check wire connections at valve—replace with waterproof wire nuts.
Test for 24VAC at valve wires when zone 6 runs.
Test at controller zone 6 terminal.
If voltage at controller but not valve → wire break.
If no voltage at controller → controller fault.
If voltage at valve but no click → replace solenoid.

Most likely: bad wire connection at valve.
