Rain Bird Timer Flashes FU5: Blown Fuse or Solenoid Short

"FU5" flashing = blown fuse (check back of panel) or short on zone 5 circuit.

Steps

Replace fuse with exact same type (e.g., 1.5A slow-blow).
If blows again → short on zone 5: check solenoid (ohms test) and wire.

Must resolve short before controller works.
