Lightning-Damaged Richdel 476PR Controller: DIY Replacement Guide

Zone Runs with No Display; Lightning Strike Suspected

The controller is destroyed. Replace it yourself:

  1. Buy an Irritrol Rain Dial or Rain Bird ESP controller ($100–$150).
  2. Label each field wire as you remove it from the old controller (terminals 1‑6, C, MV/PS).
  3. Connect wires to the same terminals on the new controller.
  4. Reconnect 120 VAC power (black‑black, white‑white, green‑ground) with power OFF.

Labor for a pro is ~$75 if you prefer not to DIY.
