Recurring Hunter XC Controller Failures: Wiring Short or Solenoid Issue?

Hunter XC Blank Display, GFI Reset Needed; Replacement Unit Also Failed

Repeated blank displays point to a field wiring short or a solenoid drawing excessive current, which trips the GFI and/or damages the controller.

Inspect all valve‑box wiring for damaged insulation, water‑filled wire nuts, or crossed wires.
Test each solenoid resistance (20–60 Ω). Replace any out‑of‑range.
Consider replacing the Hunter XC with a more robust Rain Bird ESP or Irritrol Rain Dial controller.
