Hunter SRC Plus Unreliable After 6 Years: Replace Controller

Hunter SRC Plus Intermittent Operation

After 6 years, the SRC Plus operates only with excessive button pressing—classic microprocessor or keypad membrane failure. The controller is not worth repairing.

Recommended Replacements

• Irritrol Rain Dial series (RD-600, RD-900, RD-1200) – bulletproof, easy programming.
• Rain Bird ESP series (ESP-TM2, ESP-Me, ESP-LXME) – feature-rich, excellent support.

Installation

Both use standard 24 VAC valve wiring. Label existing wires (1–5, C, MV/Pump), disconnect old, connect new. 30-minute job.

Avoid Hunter replacements if you've had repeated issues; the Rain Dial and ESP platforms have superior long-term reliability records.
