Toro ECxtra Controller Zones 2,3,4,6 Stop Working – Troubleshooting Steps

Four zones fail in auto and manual; reprogramming in B doesn’t help.

Steps

1. Check for recent digging that cut control wires.
2. Measure voltage at controller terminals for dead zones.
3. Check ohms on zone wires for opens.
4. Inspect solenoids.
5. Swap a known‑good zone wire to a dead terminal to test controller output.
6. Swap a dead zone wire to a good terminal to test field wiring/solenoid.

Solenoids often fail after power surges.
