Hardie Rain Dial Controller Runs in OFF Position: Panel Replacement

Hardie Rain Dial System Activates with Switch in OFF/STOP

A James Hardie Rain Dial controller (6, 9, or 12 station) runs irrigation even when function switch is set to OFF/STOP. The original irrigation store is closed.

Diagnosis: Worn Switch Contacts

The function switch contacts are worn, failing to break the circuit in OFF position. This is a mechanical failure in the front panel assembly.

Cost-Effective Repair: Panel Only Replacement

Hardie acquired by Irritrol; controller now sold as "Rain Dial"
Replace just the front panel (circuit board + display + switches)
Ribbon cable unplugs from case; panel snaps off plastic hinges
New panel plugs in; no rewiring needed
Cost: ~$40-50 less than full controller

Where to Purchase

Ewing Irrigation stores (California and nationwide)
Sprinkler World of Arizona: 602-954-9022 (ships panels)
Local irrigation supply houses

Full Controller Replacement Alternative

If panel unavailable or case/transformer also suspect, full Rain Dial controller replacement is straightforward. Label wires before disconnecting.
