Rain Bird RC-1260BI Advance Motor Failure

Zone Wheel Won't Auto-Advance on RC-1260BI

The controller has two motors: time motor (keeps clock, times station duration) and advance motor (rotates zone wheel). If time keeps running but zones don't advance, the advance motor is bad.

Confirm & Replace

Remove front panel (4 screws).
Locate the small motor driving the zone wheel gear.
Source replacement (24 VAC synchronous motor) from irrigation supplier.
Swap and test.

Upgrade Alternative

Given the age, strongly consider a solid-state replacement (Rain Bird ESP-TM2, ESP-Me). No motors to fail, seasonal adjust, rain sensor, multiple programs.
