Hunter SRC Controller Stuck on "OFF" After Winterization

After winterization, a Hunter SRC controller displays "OFF" constantly regardless of programming attempts. The winterization service noted they "turned off the controller box."

Two Likely Causes

  • Dial position: Controller dial may be physically set to "OFF" position instead of "AUTO/RUN"
  • Power issue: No power reaching controller (tripped breaker, unplugged transformer, GFCI trip)

Troubleshooting Steps

  1. Verify dial is set to AUTO/RUN (not OFF)
  2. Check transformer outlet—test with lamp or voltage tester
  3. Reset any GFCI outlets in garage/outside
  4. Check breaker panel for tripped irrigation circuit
  5. If powered and in AUTO but still shows OFF → controller is defective

The winterization technician likely turned the dial to OFF or unplugged the transformer. Restoring power and setting dial to RUN typically resolves this.
