Rain Bird Controller Shows "pwr off"—Power Supply Troubleshooting

Outdoor Rain Bird shows "pwr off" for 2 days. No rain. Breakers OK. 8-zone system.

"pwr off" Meaning

No power reaching controller.

Systematic Checks

  1. All breakers ON (including sub-panels)
  2. Controller plugged into outlet? Check outlet with lamp
  3. GFCI outlet tripped? (Reset any GFCI in garage/exterior)
  4. Hardwired? Check transformer: 110V in → 24VAC out?
  5. If 24VAC at controller but "pwr off" → controller failed

Transformer Test

Multimeter on transformer output: should read 24VAC. If not, replace transformer ($15-25).
